Abstract
BACKGROUND Previous studies evaluating the outcomes of hip arthroscopy for patients with global acetabular overcoverage and focal superolateral acetabular overcoverage suffer from short-term follow-up and inconsistent radiographic criteria when defining these subpopulations of patients with femoroacetabular impingement syndrome (FAIS). PURPOSE To evaluate the intermediate-term postoperative outcomes for patients with FAIS in the setting of global acetabular overcoverage, lateral acetabular overcoverage, and normal acetabular coverage. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Patients undergoing hip arthroscopy for FAIS were enrolled in a prospective cohort study, and those with a minimum follow-up of 5 years were included in this analysis. Patients were grouped based on type of acetabular coverage: global overcoverage (lateral center-edge angle [LCEA] ≥40°, with coxa profunda), lateral overcoverage (LCEA ≥40°, without coxa profunda), and no overcoverage (LCEA <40°). Functional outcomes (modified Harris Hip Score and Nonarthritic Hip Score) and failure of primary hip arthroscopy were compared between groups. RESULTS In total, 94 patients (mean age, 41.9 ± 14.2 years) were included with a mean follow-up duration of 6.1 ± 0.9 years. Of these patients, 40.4% had no acetabular overcoverage, 36.2% had lateral overcoverage, and 23.4% had global overcoverage. There was no difference between groups with respect to percentage of patients who underwent reoperation for either revision arthroscopy or conversion to total hip arthroplasty (28.9% for the normal acetabular coverage group, 29.4% for the lateral overcoverage group, and 31.8% for the global overcoverage group; P = .971). Among patients for whom primary hip arthroscopy did not fail, there was no difference in 5-year functional outcomes between groups. Postoperative LCEA >40° (β = -13.3; 95% CI, -24.1 to -2.6; P = .016), female sex (β = -14.5; 95% CI, -22.7 to -6.2; P = .001), and higher body mass index (β = -1.9; 95% CI, -2.8 to -1.0; P < .001) were associated with worse intermediate-term hip function in terms of modified Harris Hip Score. CONCLUSION There was no difference in functional outcomes or rate of reoperation at a minimum of 5 years postoperatively between those with global acetabular overcoverage, those with regional lateral overcoverage, and those with normal acetabular coverage. Provided that an appropriate acetabuloplasty is performed, there is no evidence to suggest that global acetabular overcoverage portends a worse prognosis than other FAIS subtypes.

Abstract
BACKGROUND Hip arthroscopic surgery for femoroacetabular impingement syndrome (FAIS) has proven to be an effective surgical intervention, with high rates of return to sport and work as well as favorable outcomes at short- and midterm follow-up. However, limited data exist on outcomes at long-term follow-up. PURPOSE To evaluate patient-reported outcomes (PROs) at a minimum 10-year follow-up after primary hip arthroscopic surgery including labral repair, femoral osteochondroplasty, acetabular osteochondroplasty, and capsular closure for FAIS. STUDY DESIGN Case series; Level of evidence, 4. METHODS Patients who underwent primary hip arthroscopic surgery for FAIS between June 2012 and January 2013 were identified. PROs were collected preoperatively and at a minimum of 10 years postoperatively, including the Hip Outcome Score-Activities of Daily Living (HOS-ADL), Hip Outcome Score-Sports Subscale (HOS-SS), modified Harris Hip Score (mHHS), International Hip Outcome Tool-12 (iHOT-12), and visual analog scale (VAS) for pain and satisfaction. Unique minimal clinically important difference (MCID) and patient acceptable symptom state (PASS) thresholds were calculated, and their rates of achievement were analyzed. An alpha level of <.05 was used to determine statistical significance. RESULTS A total of 94 patients (55 female; mean age, 34.3 ± 12.4 years) were analyzed with a mean follow-up of 10.1 ± 0.3 years (range, 10.0-10.7 years). Patients demonstrated significant 10-year improvement across all PRO measures (P < .001). MCID and PASS thresholds were calculated as follows: HOS-ADL (10.4 and 85.3, respectively), HOS-SS (14.6 and 60.2, respectively), mHHS (8.8 and 76.0, respectively), VAS pain (14.6 and 27.5, respectively), and iHOT-12 (PASS: 71.4). The majority of patients achieved the MCID and PASS for each PRO measure: HOS-ADL (73.4% and 70.9%, respectively), HOS-SS (78.5% and 77.2%, respectively), mHHS (81.0% and 70.9%, respectively), VAS pain (88.6% and 70.9%, respectively), and iHOT-12 (PASS: 73.4%). Overall, 9 patients (9.6%) underwent subsequent revision hip arthroscopic surgery at a mean 4.9 ± 3.7 years (range, 1.1-10.1 years) postoperatively, and 6 patients (6.4%) underwent conversion to total hip arthroplasty at a mean 4.1 ± 3.1 years (range, 0.9-9.3 years) postoperatively. CONCLUSION Patients who underwent primary hip arthroscopic surgery for FAIS utilizing contemporary methods of labral repair, acetabular and/or femoral osteochondroplasty, and capsular closure commonly experienced sustained clinical improvement and reported high levels of satisfaction at a minimum 10-year follow-up with low rates of reoperation.

Abstract
BACKGROUND Historically, symptomatic hip labral lesions were treated with arthroscopic debridement. Hip labral repair has become the standard treatment for labral pathology; however, to date, there are limited long-term studies regarding the outcomes of isolated labral debridement. PURPOSE To (1) evaluate the long-term patient-reported outcomes of isolated labral debridement, (2) report reoperation and arthroplasty rates, and (3) identify risk factors contributing to reoperation or poor clinical outcomes. STUDY DESIGN Case series; Level of evidence, 4. METHODS A retrospective review of a prospectively generated cohort of 59 hips in 57 patients from 1996 to 2010 who underwent hip arthroscopy with labral debridement was performed. Only patients with Tönnis grade <3 were included. Additionally, given the time period analyzed, resection of cam morphology was not performed, and the interportal capsulotomy was not repaired. The pre- and postoperative modified Harris Hip Score; Hip Outcome Score (HOS)-Activities of Daily Living and -Sports scores; and reoperation, conversion to total hip arthroplasty, and risk factors were analyzed. RESULTS In total, 48 hips in 47 patients (14 men, 33 women; mean age, 48.0 ± 12.9 years) met inclusion criteria and were followed for a mean of 17 ± 3 years (range, 13-27 years). The mean preoperative Tönnis grade was 1.3 ± 0.6 (range, 0-2), the mean chondral acetabular International Cartilage Regeneration & Joint Preservation Society (ICRS) grade was 1.7 ± 1.6 (range, 0-4), the mean chondral femoral ICRS grade was 0.9 ± 1.4, and the mean acetabular labral articular cartilage grade was 2.5 ± 1.2 (range, 0-4). At the final follow-up, mean the modified Harris Hip Score, HOS-Activities of Daily Living score, and HOS-Sports score were 82.2 ± 16.6, 81.9 ± 20.5, and 82.2 ± 20.5, respectively. Nineteen hips underwent subsequent reoperation at a mean of 5.5 ± 6.2 years (range, 0.5-21.2 years) postoperatively, including 16 hips (33% overall) being converted to total hip arthroplasty. Higher acetabular ICRS chondral grades at the time of surgery were observed in patients who went on to subsequent surgery compared with those who did not (2.3 ± 1.6 vs 1.1 ± 1.5; P = .02). In reoperation-free hips, Tönnis grade demonstrated a trend of increasing over time (1.4 preoperatively vs 1.7 at radiographic follow-up; P = .08). At the final follow-up, 19 hips (40%) had undergone reoperation, and 5 additional hips (10%) were rated as "abnormal" or "severely abnormal" in function, resulting in an overall clinical failure rate of 50%. CONCLUSION Isolated labral debridement was found to result in high rates of failure and reoperation, with a third of patients being converted to arthroplasty and half of patients meeting criteria for reoperation or clinical failure. Of note, for patients remaining reoperation-free, satisfactory outcome scores were observed.

Abstract
PURPOSE To determine outcomes after hip arthroscopy (HA) for femoroacetabular impingement (FAI) at a minimun 10-year follow up and identified risk factors for revision surgery. METHODS Retrospective study of a prospective database of patients undergoing HA between January 2010 and December 2011. Rim chondral injuries were evaluated using the acetabular labral articular disruptions system (ALAD). Clinical and radiological data was obtained. Cumulative survival was estimated by Kaplan-Meier and a multivariate Cox proportional hazards model. RESULTS Seventy-four patients were included in the study. Mean follow-up was 132 months. There was statistically significant improvement from preoperative PROs at latest follow-up. Seventeen patients (23.9%) underwent revision surgery. Odds ratio for revision surgery was 8.08 in a patient above 40 years old, 7.57 in a patient Tönnis greater than 1, and 4.25 in a patient ALAD 2-3. Cumulative survivorship rate at 10 years was 77.8%, with a 45.4% for patients with Tönnis grade greater than 1 in front of 85.2% for patients with Tönnis grade of 1 or less (p<.001). Risk factor for revision surgery was preoperative degree of osteoarthrosis (p=.02). CONCLUSION Cumulative survivorship rate at 10 years was 45.4% for patients with Tönnis grade greater than 1 in front of 85.2% for patients with Tönnis grade of 1 or less (p<.001). Age, chondral injuries, and degree of osteoarthrosis would increase the risk for revision surgery.

Abstract
There is a large debate revolving around the optimal surgical management of hip labral tears. Currently, the literature tends to gravitate toward labral repair as the mainstay of treatment, followed by labral reconstruction when repair is not feasible. Some studies assert that there is no difference between labral repair versus debridement, whereas others support repair. Other studies support labral reconstruction. In the end, it is the quality of the cartilage that may be most important. Intra-articular cartilage damage is more important than the labral treatment method when it comes to hip arthroscopy long-term outcomes.

Abstract
BACKGROUND Hip arthroscopy has become the mainstay surgical intervention for the treatment of femoroacetabular impingement syndrome (FAIS). However, postoperative outcomes and rates of secondary surgery are mixed in patients with differing levels of preoperative osteoarthritis (OA). Furthermore, there is a paucity of literature comparing patients with and without OA at long-term follow-up. PURPOSE To compare outcomes and rates of secondary surgery at minimum 10-year follow-up, including revision hip arthroscopy and conversion to total hip arthroplasty (THA), in patients with Tönnis grade 1 undergoing hip arthroscopy for FAIS compared with a propensity-matched control group of patients with Tönnis grade 0. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Patients who underwent primary hip arthroscopy for FAIS between January 2012 and February 2013 were identified. Patients with Tönnis grade 1 were propensity matched in a 1:2 ratio by age, sex, and body mass index (BMI) to patients with Tönnis grade 0. Patient-reported outcomes (PROs) were collected at varying timepoints including preoperatively and 1, 2, 5, and 10 years postoperatively and compared between the 2 cohorts. Rates of minimal clinically important difference (MCID) and Patient Acceptable Symptom State (PASS) achievement at 10 years were evaluated and compared between groups. Rates of secondary surgery including revision hip arthroscopy and conversion to total hip arthroplasty (THA) were evaluated. Gross survivorship between cohorts was evaluated using a Kaplan-Meier gross survivorship curve. A subanalysis was performed comparing patients with Tönnis grade 1 who converted to THA and those who did not. RESULTS A total of 31 patients with Tönnis grade 1 (age, 42.6 ± 9.0 years; BMI, 28.0 ± 6.3) were successfully matched to 62 patients with Tönnis grade 0 (age, 42.1 ± 8.5, P = .805; BMI, 26.1 ± 3.9, P = .117). Both the Tönnis grade 1 and Tönnis grade 0 groups demonstrated significant improvements regarding all PROs at minimum 10 years (P < .05 for all), except for the Hip Outcome Score Activities of Daily Living subscale (HOS-ADL) (P = .066) in the Tönnis grade 1 cohort. No significant difference (P > .05 for all) was noted between cohorts regarding any 10-year PRO. When the authors evaluated comparisons between preoperative and 1-, 2-, 5-, and 10-year PRO measures, significant differences were noted between cohorts regarding 2-year HOS-ADL (P = .021), Hip Outcome Score Sports-Specific subscale (P = .016), and modified Harris Hip Score (P = .026); otherwise, differences did not reach significance. High rates of 10-year MCID and PASS achievement were seen, with no significant differences between groups. Patients with Tönnis grade 1 had significantly higher rates of conversion to THA compared with patients who had Tönnis grade 0 (25.8% vs 4.8%; P = .006). Patients with Tönnis grade 1 had significantly lower gross survivorship compared with those who had Tönnis grade 0 (71.0% vs 85.5%, respectively; P = .04). CONCLUSION Hip arthroscopy confers comparable postoperative clinical improvements to patients who have FAIS with and without mild OA; however, the benefits among patients with mild OA may be less durable. Patients with Tönnis grade 1 had significantly higher conversion to THA and reduced gross survivorship compared with patients with no evidence of preoperative OA, suggesting that patients with evidence of OA may need to be cautioned on the higher rate of conversion surgery.

Over 50% of Studies Report Low-Back Pain Is Associated With Worse Outcomes After Hip Arthroscopy When Compared With a Control Group: A Systematic Review. Arthroscopy 2023; 39:2547-2567. [PMID: 37207922 DOI: 10.1016/j.arthro.2023.05.004] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/12/2022] [Revised: 05/03/2023] [Accepted: 05/04/2023] [Indexed: 05/21/2023]
Abstract
PURPOSE To review outcomes of patients with low-back pathology undergoing primary hip arthroscopy for the treatment of femoroacetabular impingement (FAI) syndrome. METHODS The PubMed, Cochrane Trials, and Scopus databases were queried in June 2022 to conduct this systematic review using the following terms: ("hip" OR "femoroacetabular impingement") AND ("arthroscopy" OR "arthroscopic") AND ("spine" OR "lumbar" OR "sacral" OR "hip-spine" OR "back") AND ("outcomes"). Articles were included if they reported on patient-reported outcomes (PROs) and/or clinical benefit of patients undergoing hip arthroscopy with concomitant low-back pathology. The review adhered to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) criteria. Case reports, opinion articles, review articles, and technique articles were excluded from this study. Forest plots were created to analyze preoperative and postoperative outcomes among patients with low-back pathology. RESULTS Fourteen studies were included in the review. There were 750 hips with low-back pathology and FAI (hip-spine syndrome) and 1,800 hips with only FAI (no hip-spine syndrome). All 14 studies reported PROs. In 4 studies in the group with hip-spine syndrome and 8 studies in the group with FAI without low-back pathology, the respective cohorts were reported to achieve the minimal clinically important difference in at least 1 PRO at a rate of 80%. Eight studies reported that patients with low-back pathology were associated with inferior outcomes or clinical benefit compared with patients without low-back pathology. CONCLUSIONS Patients undergoing primary hip arthroscopy with concomitant low-back pathology can expect favorable outcomes, but outcomes are superior in patients undergoing hip arthroscopy for FAI alone compared with FAI with concomitant low-back pathology. LEVEL OF EVIDENCE Level IV, systematic review of Level II to Level IV studies.

Ruzbarsky JJ, Comfort SM, Fukase N, Briggs KK, Vidal LB, Philippon MJ. Timing From Symptom Onset to Hip Arthroscopy Does Not Affect Patient-Reported Outcome Measures for the Treatment of Femoroacetabular Impingement in Adolescent Patients. Arthroscopy 2023; 39:2466-2473. [PMID: 37100216 DOI: 10.1016/j.arthro.2023.03.028] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/05/2022] [Revised: 03/30/2023] [Accepted: 03/31/2023] [Indexed: 04/28/2023]
Abstract
PURPOSE To evaluate symptom duration and its relationship to patient-reported outcomes (PROs) and survivorship after hip arthroscopy in adolescents. METHODS Patients ≤18 at time of primary hip arthroscopy for femoroacetabular impingement (FAI) between January 2011 and September 2018 were included. Exclusion criteria consisted of history of previous ipsilateral hip surgery, presence of osteoarthritis or dysplasia on preoperative radiographs, previous hip fracture, or history of slipped capital femoral epiphysis or Legg-Calve-Perthes disease. Minimum 2-year PROs (modified Harris Hip Score, Hip Outcome Score [HOS]-Activities of Daily Living, HOS-Sport Scale, Short Forms 12 [SF-12]), minimum clinically significant difference (MCID) and patient-acceptable symptom state (PASS) rates, and revision surgery rates were compared based on symptom duration. RESULTS Two-year minimal follow-up was obtained for 111 patients (134 hips) (80%), including 74 females and 37 males with a mean age of 16.4 ± 1.1 (range 13.0-18.0). The mean symptom duration was 17.2 ± 15.2 months (range 43 days to 6.0 years). Ten patients (11 hips), 6 females (7 hips) and 4 males, required revision surgery at an average of 2.3 ± 1.0 years (range 0.9-4.3 years). At a mean follow-up of 4.8 ± 2.2 years (range 2-10 years), there were statistically significant improvements in all PROs (P < .05 for all). Symptom duration showed no significant correlation to post-operative scores (correlation coefficient range -0.162 to -0.078, P > .05 for all). Symptom duration ≤12 months versus >12 months or as a continuous variable was not a predictor for requiring revision surgery or achieving MCID/PASS (95% confidence interval crosses 1 for all). CONCLUSIONS In an adolescent cohort of symptomatic FAI patients who underwent hip arthroscopy, there is no difference in PRO measures when analyzing symptom duration by arbitrary time intervals or as a continuous variable. LEVEL OF EVIDENCE Level IV, case series.

Workers' Compensation Patients Undergoing Hip Arthroscopy for Femoroacetabular Impingement Syndrome Experience Worse Mid-Term Outcomes but Similar Return-to-Work: A Propensity-Matched Analysis at 5-Year Follow-Up. Arthroscopy 2023; 39:2293-2299.e1. [PMID: 37100215 DOI: 10.1016/j.arthro.2023.03.023] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/07/2022] [Revised: 01/30/2023] [Accepted: 03/21/2023] [Indexed: 04/28/2023]
Abstract
PURPOSE To investigate mid-term patient-reported outcomes (PROs) and return-to-work for workers' compensation (WC) patients undergoing primary hip arthroscopy (HA) for femoroacetabular impingement syndrome (FAIS) versus propensity-matched, non-WC controls and to determine whether achievement rates of minimal clinically important difference (MCID) and patient-acceptable symptom state (PASS) differ between these populations. METHODS A retrospective cohort study was conducted on WC patients who underwent primary HA for FAIS from 2012 to 2017. WC and non-WC patients were propensity matched on a 1:4 basis by sex, age, and body mass index (BMI). PROs were compared preoperatively and at 5 years postoperatively, employing the Hip Outcome Score Activities of Daily Living (HOS-ADL) and Sports-Specific (HOS-SS) subscales, modified Harris Hip Score (mHHS), 12-item international Hip Outcome Tool (iHOT-12), and visual analog scales (VAS) for pain and satisfaction. MCID and PASS were calculated using published thresholds for these measures. Preoperative and postoperative radiographs and the presence and timing of return to unrestricted work were evaluated. RESULTS Forty-three WC patients were successfully matched to 172 non-WC controls and followed for 64.2 ± 7.7 months. WC patients demonstrated lower preoperative scores for all measures (P ≤ .031) and worse HOS-ADL, HOS-SS, and VAS pain scores at 5-year follow-up (P ≤ .021). There were no differences in MCID achievement rates or magnitude of change between preoperative and 5-year postoperative PROs (P ≥ .093); however, WC patients achieved PASS at lower rates for HOS-ADL and HOS-SS (P ≤ .009). 76.7% of WC and 84.3% of non-WC patients returned to work without restrictions (P = .302) at 7.4 ± 4.4 versus 5.0 ± 3.8 months, respectively (P < .001). CONCLUSIONS WC patients undergoing HA for FAIS report worse preoperative pain and function than non-WC patients and experience worse pain, function, and PASS achievement at 5-year follow-up. However, they demonstrate similar MCID achievement and magnitude improvement between preoperative and 5-year postoperative PROs, and return to work without restrictions at a similar rate to non-WC patients, although they may take longer to do so. LEVEL OF EVIDENCE Level III, retrospective cohort study.

Abstract
BACKGROUND Femoroacetabular impingement (FAI) is a common cause of hip pain, especially in young patients. When left untreated, it has been demonstrated to be a risk factor for the onset or progression of osteoarthritis (OA) and has been identified as one of the main contributors leading to the need for total hip arthroplasty (THA) at a young age. While the short-term therapeutic potential of hip arthroscopy is widely recognized, little is known regarding its potential mid- to long-term preventive effect on the progression of hip OA. PURPOSE To (1) report clinical outcomes of arthroscopically treated FAI syndrome with a minimum 5-year follow-up and compare the results to a cohort with FAI treated nonsurgically and (2) determine the influence of hip arthroscopy on the onset and progression of hip OA in patients diagnosed with FAI. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Patients who had hip pain and were diagnosed with FAI were included. Exclusion criteria were (1) previous or concomitant hip surgery, (2) <5 years of follow-up, and (3) insufficient radiographs. Patients treated with hip arthroscopy were compared with a cohort of patients with FAI who were treated nonsurgically. Kaplan-Meier estimates of failure (defined as conversion to THA) were performed. Bivariate analysis and Cox regression were used to identify factors associated with inferior clinical and radiographic outcomes. RESULTS A total of 957 patients (650 female, 307 male; 1114 hips) (mean age, 28.03 ± 8.9 years [range, 6.5-41.0 years]) with FAI were included. A total of 132 hips underwent hip arthroscopy and 982 hips were nonoperatively treated. The mean follow-up was 12.5 ± 4.7 years (range, 5.0-23.4 years). At the final follow-up, the rate of OA progression was 26.5% in the operative group and 35.2% in the nonoperative cohort (P < .01). Conversion to THA was performed in 6.8% of the surgical patients and 10.5% of the initially nonsurgical patients (P = .19). Additionally, there was no significant difference in the risk of failure between the operatively and nonoperatively treated patients. Male sex, increased age at initial diagnosis, presence of cam morphology, and increased initial Tönnis grade were risk factors for failure (male sex: hazard ratio [HR], 2.3; P < .01; per year of increased age: HR, 1.1; P < .01; presence of cam: HR, 3.5; P < .01; per Tönnis grade: HR, 4.0; P < .01). CONCLUSION At a mean follow-up of nearly 13 years, 7% of patients of the surgical group experienced progression to THA, compared with 11% of the nonoperative control group. While most of the operative group showed little to no OA at final follow-up, moderate OA (Tönnis grade 2) was present in 12% of the cohort compared with 22% of nonsurgical patients. Increased age at diagnosis, male sex, presence of a cam morphology, and presence of initial arthritic joint changes were found to be risk factors for failure. The results of this study demonstrated evidence for a preventive effect of hip arthroscopy on the development and progression of OA in young patients with FAI at mid- to long-term follow-up.

Abstract
PURPOSE To assess the 2-year outcomes of arthroscopic treatment with periportal capsulotomy closure for femoroacetabular impingement syndrome (FAIS) in patients with generalized ligamentous laxity (GLL). METHODS A retrospective analysis was performed from a prospectively collected database of FAIS patients undergoing hip arthroscopy. FAIS patients with GLL were identified as having Beighton score ≥4. FAIS patients with GLL were treated with arthroscopic labral repair, osteochondroplasty, via periportal capsulotomy with subsequent capsular closure. These patients were matched by age, sex, and body mass index (BMI) with a cohort of FAIS patients without GLL who underwent the same procedure via periportal capsulotomy without capsular closure. Preoperatively, and 2 years postoperatively, patients completed patient-reported outcomes (PRO) scores, including the Hip Disability and Osteoarthritis Outcome Score (HOOS), 12-item Short-Form survey (SF-12) and the visual analog scale (VAS). RESULTS Forty patients (5 male, 35 female) with FAIS and GLL were included (age: 29.7 ± 9.0; BMI: 23.3 ± 4.1). FAIS patients with GLL demonstrated similar significant PRO score improvements compared to a matched cohort of FAIS patients without GLL at 2 years after surgery (VAS Pain: (-)2.5 ± 3.0, (-)2.7 ± 2.7; SF-12 PCS: 17.7 ± 14.2, 16.7 ± 15.0; HOOS-Symptoms: 26.3 ± 24.0, 20.6 ± 18.1; HOOS-Pain: 29.8 ± 20.4, 24.4 ± 9.0; HOOS-ADL: 24.9 ± 18.4, 22.0 ± 19.9; HOOS-Sports: 43.6 ± 26.1, 33.1 ± 29.8; and HOOS-QOL: 44.2 ± 27.6, 41.7 ± 27.1, respectively). Both cohorts achieved minimal clinically important differences (MCID) for each HOOS subscore at equivalent high rates (70-88%). CONCLUSIONS Patients with GLL in the setting of FAIS can be effectively treated with arthroscopy via periportal capsulotomy and capsular closure. These patients demonstrate significant improvements in PRO scores at 2 years, similar to normal laxity FAIS patients undergoing arthroscopic treatment via periportal capsulotomy without capsular closure. LEVEL OF EVIDENCE Level III, retrospective comparative therapeutic trial.

Abstract
BACKGROUND Femoral torsion measurements and outcomes are variable throughout the literature and have focused on short-term follow-up. However, there is a paucity of literature investigating clinically meaningful outcomes at midterm follow-up after hip arthroscopy for femoroacetabular impingement syndrome (FAIS). PURPOSE To quantify femoral version using computed tomography imaging in patients with FAIS and to explore the relationship between version abnormalities and 5-year outcomes after hip arthroscopy. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Patients who underwent primary hip arthroscopy for FAIS between January 2012 and November 2017 were identified. Patients were included if they had 5-year follow-up with completion of ≥1 patient-reported outcome (PRO) scores and excluded if they had Tönnis grade >1, revision hip surgery, a concomitant hip procedure, a developmental disorder, or a lateral center-edge angle <20°. Torsion groups were defined as severe retrotorsion (<0°), moderate retrotorsion (0.1°-5°), normal torsion (5.1°-20°), moderate antetorsion (20.1°-25°), and severe antetorsion (>25.1°) based on computed tomography measurements. Patient characteristics were analyzed among the torsion cohorts, as were preoperative and 5-year PROs: Hip Outcome Score-Activities of Daily Living, Hip Outcome Score-Sports Subscale, modified Harris Hip Score, international Hip Outcome Tool, visual analog scale for pain, and visual analog scale for satisfaction. Achievement rates of cohort-specific thresholds for the minimal clinically important difference and Patient Acceptable Symptom State were calculated and compared among cohorts. RESULTS A total of 362 patients (244 female, 118 male; mean ± SD age, 33.1 ± 11.5 years; body mass index, 26.9 ± 17.8) met inclusion/exclusion criteria and were analyzed at a final mean follow-up of 64.3 ± 9.4 months (range, 53.5-115.5 months). Mean femoral torsion was 12.8°± 9.2°. The number of patients within each group was 20 for severe retrotorsion (torsion, -6.3°± 4.9°), 45 for moderate retrotorsion (2.7°± 1.3°), 219 for normal torsion (12.2°± 4.1°), 39 for moderate antetorsion (21.9°± 1.3°), and 39 for severe antetorsion (29.0°± 4.2°). No significant differences in age, body mass index, sex, smoking status, workers' compensation, psychiatric history, back pain, or physical activity were found among the torsional groups. All groups demonstrated significant improvements at 5 years postoperatively (P < .01 for all). All torsion subgroups demonstrated similar pre- to postoperative changes in PROs (P≥ .515) and PRO values at 5-year follow-up (P≥ .098). There were no significant differences in the achievement of the minimal clinically important difference (P≥ .422) or Patient Acceptable Symptom State (P≥ .161) for any of the PROs among the torsion groups. CONCLUSION The orientation and severity of femoral torsion at the time of hip arthroscopy for FAIS in this study's cohort did not affect the propensity for clinically meaningful outcome improvement at midterm follow-up.

Abstract
Common hip internal derangements include femoroacetabular impingement (FAI), developmental dysplasia of hip (DDH) dysplasia, and avascular necrosis (AVN) of the femoral head. These are initially screened by radiographs. For preoperative planning of hip preservation, 3-dimensional (3D) CT is commonly performed to assess bony anatomy and its alterations. Magnetic resonance imaging (MRI) is used to evaluate labrum, hyaline cartilage, tendons, synovium, and loose bodies, and provides vital information for surgical decision-making. However, conventional 2D MRI techniques are limited by lack of isotropic multiplanar reconstructions and partial volume artifacts. With advancements in hardware and software, novel isotropic 3D MR Proton Density images are acquired with acceptable acquisition times leading to improved visualization of soft tissue and osseous structures for various hip conditions. Three-Dimensional MRI allows multiplanar non-gap reconstructions along the structures of interest. It results in detection of small, otherwise inconspicuous labral tears without the need for MR arthrogram, which can be subsequently measured. In addition, radial reconstructions of the femoral head can be performed from original 3D volume MR imaging and CT imaging without the need for individual different plane acquisitions. Three-Dimensional MRI thus impacts surgical decision-making for the important common hip derangement conditions. For example, femoral head hyaline cartilage loss may make hip preservation difficult or impossible. In this review, we discuss the advantages and technical details of 3D CT and MRI and their significant role in aiding hip preservation surgery for common hip conditions. The conditions discussed in this article include FAI, DDH, AVN, synovial disorders, cartilaginous tumors, and hip fractures.

Abstract
Aims Hip arthroscopy (HA) has become the treatment of choice for femoroacetabular impingement (FAI). However, less favourable outcomes following arthroscopic surgery are expected in patients with severe chondral lesions. The aim of this study was to assess the outcomes of HA in patients with FAI and associated chondral lesions, classified according to the Outerbridge system. Methods A systematic search was performed on four databases. Studies which involved HA as the primary management of FAI and reported on chondral lesions as classified according to the Outerbridge classification were included. The study was registered on PROSPERO. Demographic data, patient-reported outcome measures (PROMs), complications, and rates of conversion to total hip arthroplasty (THA) were collected. Results A total of 24 studies were included with a total of 3,198 patients (3,233 hips). Patients had significantly less improvement in PROMs if they had Outerbridge grade III and IV lesions (p = 0.012). Compared with microfracture, autologous matrix-induced chondrogenesis (AMIC) resulted in significantly reduced rates of conversion to THA (p = 0.042) and of revision arthroscopy (p = 0.038). Chondral repair procedures in these patients also did not significantly reduce the rates of conversion to THA (p = 0.931), or of revision arthroscopy (p = 0.218). However, compared with microfracture, AMIC significantly reduced the rates of conversion to THA (p = 0.001) and of revision arthroscopy (p = 0.011) in these patients. Those with Outerbridge grade III and IV lesions also had significantly increased rates of conversion to THA (p = 0.029) and of revision arthroscopy (p = 0.023) if they had associated lesions of the acetabulum and femoral head. Those who underwent labral debridement had a significantly increased rate of conversion to THA compared with those who underwent labral repair (p = 0.015). Conclusion There is universal improvement in PROMs following HA in patients with FAI and associated chondral lesions. However, those with Outerbridge grade III and IV lesions had significantly less improvement in PROMs and a significantly increased rate of conversion to THA than those with Outerbridge grade I and II. This suggests that the outcome of HA in patients with FAI and severe articular cartilage damage may not be favourable.

Abstract
BACKGROUND Hip arthroscopy is an effective treatment tool for athletes with femoroacetabular impingement (FAI) syndrome. However, long-term data are scarce. PURPOSE To assess survivorship, minimum 10-year patient-reported outcome measures (PROMs), and sports participation after primary hip arthroscopy for FAI syndrome in athletes and to perform a propensity-matched comparison between patients undergoing labral debridement and labral repair. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Athletes who underwent hip arthroscopy for FAI syndrome between February 2008 and December 2010 were eligible. Exclusion criteria were other ipsilateral hip condition, Tönnis grade ≥2, or no baseline PROMs. Survivorship was defined as no conversion to total hip arthroplasty. The Patient Acceptable Symptom State (PASS), minimal clinically important difference (MCID), maximum outcome improvement (MOI) satisfaction threshold, and sports participation were reported. A propensity-matched comparison between labral debridement and labral repair was performed. Two additional propensity-matched subanalyses were performed for capsular management and cartilage damage. RESULTS In total, 189 hips (177 patients) were included. The mean ± SD follow-up was 127.2 ± 6.0 months. Survivorship was 85.7%. Significant improvement in all PROMs was reported (P < .001). A total of 46 athletes with labral repair were propensity matched to 46 athletes with labral debridement. This subanalysis demonstrated significant and comparable improvement in all PROMs at minimum 10-year follow-up (P < .001). For the labral repair group, the PASS achievement rates were 88.9% for the modified Harris Hip Score (mHHS) and 80% for the Hip Outcome Score-Sport Specific Subscale (HOS-SSS); the MCID achievement rates were 80.6% for the mHHS and 84% for HOS-SSS; and for the MOI satisfaction threshold, rates were 77.8%, 80.6%, and 55.6% for the mHHS, Nonarthritic Hip Score, and visual analog scale, respectively. For the labral debridement group, the PASS achievement rates were 85.3% for the mHHS and 70.4% for the HOS-SSS; the MCID achievement rates were 81.8% for the mHHS and 74.1% for HOS-SSS; and for the MOI satisfaction threshold, rates were 72.7%, 81.8%, and 66.7% for the mHHS, Nonarthritic Hip Score, and visual analog scale. Total hip arthroplasty conversions occurred significantly sooner with labral debridement than labral repair (P = .048). Age was identified as a significant predictor of achieving the PASS. CONCLUSION Primary hip arthroscopy for FAI syndrome in athletes results in 85.7% survivorship and sustained PROM improvement at a minimum 10-year follow-up. A significant time delay to total hip arthroplasty conversion at 10-year follow-up was reported with labral repair over debridement, although this should be interpreted with caution, as the total number of conversions was small.

Abstract
BACKGROUND Limited literature exists regarding how postoperative physical therapy (PT) may affect outcomes in patients with femoroacetabular impingement syndrome (FAIS) undergoing hip arthroscopy. Additionally, it is unknown how PT measures relate to traditional orthopaedic patient-reported outcomes (PROs). PURPOSE To evaluate how the duration of PT may correlate with outcomes in patients with FAIS using both the Lower Extremity Functional Scale (LEFS) and standard orthopaedic PRO measures. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Patients from a single institution who underwent primary hip arthroscopy for FAIS between 2013 and 2016 were identified. Patients with a minimum 2-year follow-up and fully documented PT notes were included and stratified into 3 cohorts based on timing of PT discharge: 0 to 3 months, 3 to 6 months, and 6 to 12 months. Predictive regression models were developed to analyze the rate of improvement (ROI) in LEFS score as it relates to (1) postoperative day (POD) and (2) postoperative PT session number. Two-year PROs were collected, correlated with LEFS scores, and compared among cohorts. RESULTS A total of 95 patients were included (mean ± SD age, 34.6 ± 11.7 years; range, 14-55 years). Mean LEFS scores increased significantly from the initial score at 6 weeks, 3 months, and the time of PT discharge (P < .01 for all). The predicted ROI in LEFS score was 3.39% per PT session for sessions 0 to 13, 1.43% for sessions 14 to 27, and 0.37% for sessions 28 to 40. Patients who underwent 3 to 6 months of PT had significantly better Hip Outcome Score (HOS) relative to the 0- to 3-month cohort and significantly better visual analog scale (VAS) scores for satisfaction relative to the 6- to 12-month cohort. The predicted ROI in LEFS score was 0.96% per day from POD 0 to 45, 0.22% from POD 46 to 139, and 0.03% after POD 139. Moderate correlations were seen between LEFS score at the time of discharge and all 2-year PROs as follows: HOS Activities of Daily Living subscale (r = 0.488), HOS Sports-Specific subscale (r = 0.500), modified Harris Hip Score (r = 0.465), 12-item International Hip Outcome Tool (r = 0.494), VAS pain score (r = -0.346), and VAS satisfaction score (r = 0.459). CONCLUSION Patients undergoing hip arthroscopy for FAIS derived substantial benefit from each PT visit during their first 13 PT sessions and then a smaller, yet still meaningful benefit from sessions 13 through 27. After session 40, or approximately 4.5 to 5 months, patients no longer benefited from additional PT sessions. Based on PRO scores, patients discharged from PT between 3 and 6 months had the best 2-year outcomes. LEFS score had moderate correlation with orthopaedic PRO scores.

Low Rates of 5-Year Secondary Surgery and Postoperative Complications After Primary Hip Arthroscopy in More Than 30,000 Patients. Arthroscopy 2023; 39:1639-1648. [PMID: 37286283 DOI: 10.1016/j.arthro.2023.01.100] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/06/2022] [Revised: 12/12/2022] [Accepted: 01/24/2023] [Indexed: 06/09/2023]
Abstract
PURPOSE To evaluate 90-day complications, 5-year secondary surgery rates, and risk factors for secondary surgery following primary hip arthroscopy performed for femoroacetabular impingement and/or labral tears using a large national dataset. METHODS A retrospective analysis was conducted using the PearlDiver Mariner151 database. Patients with International Classification of Diseases, Tenth Revision, diagnosis codes for femoroacetabular impingement and/or labral tear undergoing primary hip arthroscopy with femoroplasty, acetabuloplasty, and/or labral repair between 2015 and 2021 were identified. Those with concomitant International Classification of Diseases, Tenth Revision, codes for infection, neoplasm, or fracture were excluded, as were patients with a history of previous hip arthroscopy or total hip arthroplasty, or age ≥70 years. Rates of complications within 90 days of surgery were assessed. Five-year rates of secondary surgery-revision hip arthroscopy or conversion to total hip arthroplasty-were determined by Kaplan-Meier analysis, and risk factors for secondary surgery were identified by multivariate logistic regression. RESULTS A total of 31,623 patients underwent primary hip arthroscopy from October 2015 to April 2021, with annual volumes ranging from 5,340 to 6,343 surgeries per year. Femoroplasty was the most frequent surgical procedure (performed in 81.1% of surgical encounters), followed by labral repair (72.6%) and acetabuloplasty (33.0%). Ninety-day postoperative complication rates were low, with 1.28% of patients experiencing any complication. The 5-year secondary surgery rate was 4.9% (N = 915 patients). Multivariate logistic regression identified age <20 years (odds ratio [OR] 1.50; P < .001), female sex (OR 1.33; P < .001), class I obesity (body mass index 30-34.9: OR 1.30; P = .04), and class II/III obesity (body mass index ≥35.0: OR 1.29; P = .02) as independent predictors of secondary surgery. CONCLUSIONS In this study of primary hip arthroscopy, 90-day adverse events were low at 1.28%, and the 5-year secondary surgery rate was 4.9%. Age younger than 20 years, female sex, and obesity were risk factors for secondary surgery, suggesting the need for increased surveillance in these patient groups. LEVEL OF EVIDENCE Level IV, case series.

Editorial Commentary: Hip Arthroscopy in Patients With Early Degeneration Who Receive Intra-Articular Bone Marrow Aspirate Concentrate Can Achieve Outcomes Similar to Nonarthritic Patients. Arthroscopy 2023; 39:1438-1439. [PMID: 37147073 DOI: 10.1016/j.arthro.2023.01.017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/15/2023] [Accepted: 01/16/2023] [Indexed: 05/07/2023]
Abstract
The management of patients with early joint degeneration is challenging. In this setting, biologic interventions, from platelet-rich plasma to bone marrow aspirate concentrate (BMAC) to hyaluronic acid, may be beneficial. Recent research, with 2-year follow-up, shows that patients with early degenerative changes (Tönnis grade 1 or 2) who received intra-articular injection of BMAC after hip arthroscopy procedure had improvements in outcomes similar to nonarthritic patients (Tönnis 0) with symptomatic labral tears who underwent arthroscopy and did not receive BMAC. Although confirmatory investigation using patients with early degenerative changes as a control is required, it is possible that with BMAC, patients with early degenerative changes of their hip could achieve functional outcomes similar to patients with nonarthritic hips.

Abstract
PURPOSE To assess 5-year outcomes and survival rate of hip arthroscopy (HA) for femoroacetabular impingement syndrome (FAIS) and to determine achievement rates of clinically significant outcomes. METHODS Three databases were searched around the following terms: hip arthroscopy, FAIS, and 5-year follow-up. Articles available in English, presenting original data, and reporting minimum 5-year follow-up after primary HA using either patient reported outcomes (PROs) or conversion to total hip arthroplasty (THA) and/or revision surgery were included. Quality assessment was completed using MINORS assessment, and relative agreement was calculated using Cohen's kappa. RESULTS Fifteen articles were included. MINORS assessment ranged from 11-22, with excellent (k=0.842) inter-rater reliability between reviewers. 2080 patients were included at a follow-up range of 60.0-84 months. Labral repair was the most commonly performed procedure (range: 8.0%-100%). All studies included PROs and all reported statistically significant improvement (p<0.05) at the 5-year timepoint. The most frequent PRO reported was modified Harris Hip Score (mHHS) (n=8). Nine studies reported on clinically significant outcome achievement, with mHHS being the most common (n=8). The rate of achieving minimal clinically important difference (MCID) ranged from 64-100%, patient-acceptable symptomatic state (PASS) ranged from 45-87.4%, and substantial clinical benefit (SCB) ranged from 35.3-66%. Conversion to THA and revision surgery varied across studies, with ranges of 0.0%-17.9% (duration: 28.8-87.1 months) and 1.3%-26.7% (duration: 14.8-83.7 months), respectively. The most common definition of failure was conversion to THA or revision (n=7). Increased age (n=5) and greater joint degeneration (n=4) were the most common predictors of clinical failure. CONCLUSIONS Patients undergoing primary hip arthroscopy for FAIS demonstrate significant improvement at 5-year follow-up, with maintained rates of achievement of MCID, PASS, and SCB. Survival rate of HA at 5-years is overall high, with ranges of 0.0-17.9% and 1.3-26.7% % conversion to THA or revision surgery, respectively. Across studies, increased age and greater joint degeneration were the most common cited predictors of clinical failure.

Abstract
PURPOSE The purpose of this study was to perform a systematic review of studies reporting on minimum 5-year outcomes of patients undergoing primary hip arthroscopy (HA) for femoroacetabular impingement syndrome (FAIS) to determine whether capsular management influences patient-reported outcomes (PROs), rates of clinically significant outcome, and rates of revision surgery or conversion to total hip arthroplasty (THA). METHODS PubMed, Scopus, and Google Scholar were searched around the terms hip arthroscopy, FAIS, five-year follow-up, and capsule management. Articles available in English, presenting original data, and reporting minimum 5-year follow-up after HA using either PROs or conversion to THA and/or revision surgery were included. Quality assessment was completed using MINORS assessment. Articles were stratified into unrepaired and repaired capsule cohorts (excluding periportal capsulotomy techniques). RESULTS Eight articles were included. MINORS assessment ranged from 11-22, with excellent (k=0.842) inter-rater reliability. Populations without capsular repair were identified in four studies including a total of 387 patients, at an age of 33.1-38.0 years and follow-up range of 60.0-77 months. Populations with capsular repair were identified in five studies including a total of 835 patients, at an age range of 33.6-43.1 years and follow-up range of 60.0-78.0 months. All studies included PROs and all reported significant improvement (p<0.05) at the 5-year timepoint, with modified Harris Hip Score (mHHS) being the most frequent (n=6). No differences were noted between groups regarding any of the measured PROs. Average rates of achieving MCID and PASS for mHHS were similar between patients without capsular repair (MCID 71.1%, PASS 73.7%, n=1) and with capsular repair (MCID 66.0%-90.6%, PASS 55.3%-87.4%, n=4). Conversion to THA occurred in 12.8-18.5% and 0.0-29.0% for patients with an unrepaired and repaired capsule, respectively. Revision HA occurred in 15.4-25.5% and 3.1-15.4% in unrepaired and repaired capsular patients, respectively. CONCLUSIONS Patients undergoing hip arthroscopy for FAI had significant improvement in PRO scores at minimum 5-year follow-up, and scores did not differ between patients that underwent capsular repair and those that did not. Similar rates of markers of clinical benefit and THA conversion were achieved by both groups; however, lower rates of revision hip arthroscopy were demonstrated in the capsular repair cohort.

Abstract
BACKGROUND Staged bilateral hip arthroscopy is an option for athletes who have symptomatic bilateral femoroacetabular impingement; however, the optimal timing of the second procedure is unknown. PURPOSE To evaluate minimum 2-year outcomes for patients undergoing accelerated bilateral arthroscopy against those undergoing (1) delayed bilateral and (2) unilateral arthroscopy. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS A retrospective review was performed of prospectively collected data from patients undergoing bilateral primary hip arthroscopy for femoroacetabular impingement between 2009 and 2022. Inclusion criteria entailed competitive athletes with concurrent bilateral symptoms at initial presentation. Exclusion criteria (either hip) were Tönnis grade >1, dysplasia (lateral center-edge angle <25°), Perthes disease, protrusio acetabuli, and avascular necrosis. Two groups were established based on the duration between procedures: within 7 days (accelerated group) and within 4 to 12 weeks (delayed group). Patients from the accelerated group were matched in a 1:2 ratio with patients undergoing unilateral surgery based on age ±2 years, sex, and athletic status. Minimum 2-year postoperative patient-reported outcomes (PROs) (including modified Harris Hip Score, University of California Los Angeles activity scale, 36-Item Short Form Health Survey, and Western Ontario and McMaster Universities Osteoarthritis Index), rates of achieving the minimal clinically important difference, rates of continuing to play main sport, and satisfaction were compared between groups. RESULTS A total of 131 athletes (262 hips) with bilateral femoroacetabular impingement were included: 91 in the accelerated group and 40 in the delayed group. Duration between surgeries was 0.99 ± 0.02 and 6.35 ± 2.18 weeks, respectively. All accelerated athletes were each successfully matched to 2 athletes with unilateral procedures (N = 182). All 3 groups demonstrated significant improvement from baseline across all PROs (P < .001 for all). Acquired change in PROs was similar and not significantly different between groups (P > .05). Satisfaction with relief from pain was achieved by 85.9% of patients in the accelerated group compared with 83.1% in the delayed group (P = .053) and 87.3% in the unilateral group (P = .933). The minimal clinically important difference for the modified Harris Hip Score was achieved by 84.9% of patients in the accelerated group compared with 91.5% in the delayed group (P = .212) and 87.6% in the unilateral group (P = .456). At 2 years postoperatively, the continue-to-play rate was 73.6% for the accelerated group compared with 77.1% for the delayed group (P = .577) and 73.0% for the unilateral group (P = .903). There were no increased complications associated with the accelerated group. CONCLUSION Accelerated bilateral hip arthroscopy 1 week apart was a safe and effective treatment option for athletes with bilateral symptoms. Improvement in PROs and continue-to-play rates were comparable with those after a delayed duration between procedures and with those case-control matched athletes undergoing unilateral arthroscopy.

Abstract
BACKGROUND The arthroscopic management of borderline hip dysplasia (BHD) is controversial, and long-term follow-up data are scarce. The purpose of this study was to report prospectively collected survivorship and patient-reported outcome measures (PROMs) at a minimum 10-year follow-up following primary hip arthroscopy with capsular plication and labral preservation in patients with BHD. METHODS Data were prospectively collected on all patients who underwent primary hip arthroscopy between September 2008 and September 2011. Patients with BHD (defined by a lateral center-edge angle [LCEA] between 18° and 25°) were included. Preoperative and minimum 10-year follow-up scores for the modified Harris hip score (mHHS), Nonarthritic Hip Score (NAHS), Hip Outcome Score-Sports Specific Subscale (HOS-SSS), and visual analog scale (VAS) for pain were collected. Exclusion criteria were prior ipsilateral hip surgery, Workers' Compensation status, Tönnis grade of >1, previous hip conditions, or LCEA of <18°. Survivorship was defined as no conversion to total hip arthroplasty (THA). The risk factors for THA conversion were analyzed. The achievement rate for the minimal clinically important difference (MCID) was reported. A propensity-matched comparison with a control group without BHD was performed. RESULTS Forty-five (80%) of 56 eligible hips were included in this study: 38 hips (84%) of female patients and 7 hips (16%) of male patients. The mean patient age was 31.0 ± 12.9 years, and the mean patient body mass index (BMI) was 24.5 ± 5.4 kg/m2. The 10-year survivorship was 82.2%, and there was significant improvement in all PROMs and VAS pain from baseline to the minimum 10-year follow-up (p < 0.001). The odds of undergoing conversion to THA were 4.4 times higher for patients with a BMI of ≥23 kg/m2 and 7.1 times higher for patients who were ≥42 years of age. The MCID was achieved at high rates for the mHHS (79%), NAHS (79%), HOS-SSS (70%), and VAS pain (76%). The minimum 10-year survivorship, PROMs, and MCID achievement rates for the BHD group were comparable with those for the control group. CONCLUSIONS Patients with BHD who underwent primary hip arthroscopy with capsular plication and labral preservation demonstrated an overall survivorship of 82.2% and significant improvement in all PROMs and achieved the MCID at high rates at a minimum 10-year follow-up.

Abstract
BACKGROUND A limited joint space (<2 mm) is associated with poorer outcomes and conversion to total hip arthroplasty (THA) after hip arthroscopic surgery. As indications for hip arthroscopic surgery expand, it is important to reevaluate established risk factors among large patient populations. PURPOSE To reevaluate the relationship between the radiographic joint space and outcomes after hip arthroscopic surgery and to assess the validity of a joint space of 2 mm as the accepted cutoff for successful hip arthroscopic surgery. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Patients aged 18 to 50 years who underwent hip arthroscopic surgery for femoroacetabular impingement between January 2008 and December 2016 and had a minimum 2-year follow-up were included. Patients with previous ipsilateral hip surgery, a history of hip fractures, dysplasia (lateral center-edge angle <20°), or osteoarthritis (Tonnis grade >2) were excluded. The joint space was categorized as diminished (≤2 mm), borderline (>2 to ≤3 mm), or preserved (>3 mm). Minimum 2-year patient-reported outcomes (modified Harris Hip Score [mHHS], Hip Outcome Score-Activities of Daily Living [HOS-ADL], Hip Outcome Score-Sports-Specific Subscale [HOS-SSS]), revision rates, and rates of conversion to THA were compared between groups. RESULTS A total of 699 patients (782 hips) with a mean age of 33.8 ± 10.1 years met 2-year inclusion criteria. The mean follow-up time was 4.2 ± 2.1 years. Overall, 51 hips (6.5%) had a diminished joint space, 297 (38.0%) had a borderline joint space, and 434 (55.5%) had a preserved joint space. Patients with a diminished joint space had larger femoral and acetabular defects compared with those with larger joint spaces. All groups had improved patient-reported outcome scores compared with baseline (P < .001 for all), and there were no differences between the groups in the percentage of patients who reached the minimal clinically important difference or patient acceptable symptom state. There were also no differences between the groups in revision rates (P = .95). A greater number of hips with a diminished joint space converted to THA (n = 8 [15.7%]) compared with those with a borderline (n = 9 [3.0%]) or preserved (n = 9 [2.1%]) joint space (P < .001). Considering joint space as a continuous variable, adjusted logistic regression showed that for every millimeter decrease in the joint space, the odds of conversion to THA increased by a factor of 2.5 (odds ratio, 2.5 [95% CI, 1.6-3.8]). CONCLUSION This study demonstrated that patients with a diminished joint space were at a higher risk of conversion to THA. Although 2 mm should not serve as a strict cutoff, patients should be counseled based on their preoperative radiographic findings accordingly.

Abstract
Background There is a paucity of literature reporting outcomes after revision hip arthroscopic surgery in obese patients. Purpose To report the minimum 5-year survivorship, patient-reported outcomes (PROs), clinical benefit, and risk factors for conversion to total hip arthroplasty (THA) in obese patients after revision hip arthroscopic surgery. Study Design Case series; Level of evidence, 4. Methods Data were prospectively collected and retrospectively reviewed for patients who underwent revision hip arthroscopic surgery by a single surgeon between April 2010 and August 2016. Inclusion criteria were a body mass index ≥30 and baseline and minimum 5-year postoperative values for the modified Harris Hip Score (mHHS), Nonarthritic Hip Score (NAHS), Hip Outcome Score-Sport-Specific Subscale (HOS-SSS), and visual analog scale (VAS) for pain. Exclusion criteria were Tönnis grade >1 and hip dysplasia. Survivorship was defined as no conversion to THA. Clinical benefit was measured using the minimal clinically important difference (MCID). Survivors and nonsurvivors underwent further bivariate and regression analyses to determine the predictors of conversion to THA. Results Included were 24 hips in 24 patients. The mean patient age was 39.3 ± 12.7 years, and the mean follow-up was 83.9 ± 26.5 months. The survivorship rate was 75.0%, and patients demonstrated a significant improvement in all PROs (P < .01). At 5-year follow-up, the MCID for the mHHS, NAHS, HOS-SSS, and VAS was achieved by 70.6%, 94.1%, 92.9%, and 64.7%, respectively, of the patients. Older age, higher grade ligamentum teres tears, and acetabuloplasty were significant on bivariate analysis for conversion to THA, and increased age was identified as a significant variable for conversion to THA on regression analysis (odds ratio, 1.297 [95% CI, 1.045-1.609]; P = .018), with a 29.7% greater risk for every additional year of age at the time of revision. Conclusion In this study, 25.0% of obese patients who underwent revision hip arthroscopic surgery required conversion to THA. The study patients who did not need conversion to THA had a significant improvement in all PROs, with >90% achieving MCID for one or more outcome measures. Older age was identified as a significant predictor of conversion to THA.

Abstract
BACKGROUND Femoroacetabular impingement (FAI) is often a chronic problem, which can lead to a decrease in mental well-being. PURPOSE/HYPOTHESIS The purpose of this study was to determine patient mental health improvement after hip arthroscopy and if this improvement correlated with improved outcomes. It was hypothesized that patients with low mental health (LMH) status would improve after hip arthroscopy for FAI and that their patient-reported outcomes (PROs) would significantly improve after surgery. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Patients who underwent hip arthroscopy with labral repair between 2008 and 2015 were included. The minimum follow-up was 2 years. PROs included the modified Harris Hip Score (mHHS), Hip Outcome Score-Activities of Daily Living (HOS-ADL), HOS-Sports (HOS-Sports), and 12-Item Short Form Health Survey (SF-12). The minimal clinically important difference and Patient Acceptable Symptom State (PASS) were determined for HOS-ADL, HOS-Sports, and the mHHS based on previously published studies. Patients who scored <46.5 on the SF-12 Mental Component Summary (MCS) were in the LMH group, and those who scored ≥46.5 were in the high mental health (HMH) group. RESULTS In total, 120 (21%) of the 566 patients were in the LMH group and 446 (79%) patients were in the HMH group preoperatively. There was no difference in age or sex between groups. Patients in the LMH group had lower mHHS, HOS-ADL, and HOS-Sports at the mean 4-year follow-up and were less likely to reach PASS for the scores. Postoperatively, 84% (478/566) of the entire group was in the HMH group. A total of 88 (73%) of the LMH group improved to HMH. A multiple linear regression model for change in MCS identified independent predictors of changes in preoperative MCS to be LMH group preoperatively, change in HOS-Sports, and change in mHHS (r2 = 0.4; P < .001). CONCLUSION HMH was achieved in 84% of the patients after hip arthroscopy for FAI. Improvement in MCS was correlated with function and activity, as indicated by a significant correlation with HOS-ADL and HOS-Sports. A small percentage of patients did see a decline in their MCS score. This study showed that patients with LMH scores before hip arthroscopy for FAI can improve to normal/high mental health, and this correlated with higher PROs.

Abstract
BACKGROUND Femoroacetabular impingement (FAI) in patients with dysplasia presents a unique challenge to surgeons. Short-term outcomes are conflicting, while longer term follow-up data are only emerging. PURPOSE To quantify midterm (minimum 5-year follow-up) outcomes after the arthroscopic correction of FAI in the presence of lateral rim dysplasia compared with a matched control group with FAI with normal acetabular coverage. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Prospective outcome data, collected in a consecutive series of patients undergoing arthroscopic FAI correction with lateral rim dysplasia (lateral center-edge angle [LCEA] of 13°-25°), were reviewed (N = 75 cases). An age- and sex-matched control group of 120 cases was also formed (LCEA >25°). Survivorship was defined as the avoidance of total hip replacement and assessed using a Kaplan-Meier curve with the log-rank test. Survival rates and patient-reported outcome measure (PROM) scores (modified Harris Hip Score [mHHS], University of California, Los Angeles [UCLA], 36-Item Short Form Health Survey [SF-36], and Western Ontario and McMaster Universities Osteoarthritis Index [WOMAC] preoperatively and at 5 years postoperatively) were compared between the groups. The proportion of patients across groups achieving the minimal clinically important difference (MCID) was compared for each PROM. The dysplasia group was also analyzed independently to identify any factors that may indicate a less favorable outcome using regression analysis. The group was divided into 2 subgroups: borderline dysplasia (LCEA of 20°-25°) and severe dysplasia (LCEA <20°). RESULTS The survival rate in the dysplasia group was 97%. There was no statistical difference with respect to survival rates or any PROM scores (P > .05 for all) between the groups. There were similar rates of achieving the MCID between the groups for the mHHS, UCLA, and WOMAC. The FAI control group had a higher rate of achieving the MCID for the SF-36 (P = .012; effect size = 0.274 [small]). Subgroup analysis indicated a lower survival rate (78% vs 100%, respectively; P < .001) in female cases in the dysplasia group (n = 9) compared with male cases in the dysplasia group (n = 66). The UCLA score in female cases in the dysplasia group at 5 years was statistically lower compared with that in male cases in the dysplasia group (6 vs 10, respectively; P = .003; effect size = 0.378 [medium]), but no other outcome revealed any differences between the sexes. There were also no variables identified on regression analysis that accurately predicted a poorer outcome in the dysplasia group. When stratified by severity, there was no difference in survivorship or outcomes between those with severe dysplasia (LCEA <20°; n = 11) and those with borderline dysplasia (LCEA of 20°-25°; n = 64). CONCLUSION An arthroscopic intervention was a successful treatment option for FAI in the presence of lateral rim dysplasia at midterm follow-up. Irrespective of the severity of dysplasia, patients can expect similar improvements to those in patients with normal femoral head coverage.

Abstract
PURPOSE To provide an updated review of recent literature on postoperative outcomes following hip arthroscopy for femoroacetabular impingement syndrome (FAIS), focusing on larger-population studies with a minimum 2-year follow-up published within the last 5 years. METHODS A literature search of the PubMed, Ovid Medline, Web of Science, and Cochrane databases was performed in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Articles were screened for clinical studies published from 2017 to 2022 with greater than 100 patients and minimum 2-year follow-up. Exclusion criteria included failure to report postoperative patient-reported outcomes (PROs), no preoperative radiographic measurements, and surgery for pathology other than FAIS. Data collection included study characteristics, patient demographics, radiographic findings, intraoperative findings, procedures performed, postoperative PROs, and subsequent surgeries. RESULTS Nine studies met inclusion criteria. Mean or median patient ages ranged from 32.3 to 41 years, with 4 studies reporting on greater than 50% female patients. Mean preoperative lateral center edge angles and alpha angles ranged from 30.2° to 37° and from 56.2° to 71°, respectively. Labral repairs (range 69.7%-100%) were performed more commonly than debridements (range 0%-26.3%). All studies demonstrated improved PROs at most recent follow-up. Seven studies reported mean or median modified Harris Hip Scores, with preoperative and postoperative values that ranged from 53.1 to 80 and from 67.4 to 100, respectively. Revision hip arthroscopies and conversions to hip arthroplasty ranged from 0.8% to 11.6% and from 0% to 34%, respectively. CONCLUSIONS All included studies found improvements in PROs after hip arthroscopy for FAIS at a minimum of 2-year follow-up. Conversion to total hip arthroplasty is most common in older patients at minimum 10-year follow-up. LEVEL OF EVIDENCE Level IV, systematic review of Level I through IV studies.

Abstract
PURPOSE To evaluate minimum 5-year outcomes and survivorship after primary hip arthroscopy in athletes. METHODS A systematic review of current literature was performed with the following key words: "hip arthroscopy," "long-term," "outcomes," "ten-year," "survivorship," "10-year," "5-year," "five-year," "midterm," "athlete," "sport," and "femoroacetabular impingement" in PubMed, Cochrane Trials, and Scopus in April 2022 using the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. Study and demographic variables such as title, author, publication date, study design, demographic, number of hips, follow-up time, study period, indications for hip arthroscopy, patient-reported outcome scores, and rates of secondary surgeries and conversion to total hip arthroplasty. Radiographic, intraoperative surgical treatment, and clinical benefit was documented as well. RESULTS Ten studies that captured data on 691 hips were included in this study. Eight studies reported mean and standard deviation for the modified Harris Hip Score. Significant improvements were reported in all studies with postoperative scores ranging from 83.3 to 94.4 (standardized mean difference [SMD] 1.65; 95% confidence interval [CI] 1.39-1.91, P < .00001). Eight studies reported significant improvement in Hip Outcome Score - Sports Specific Scale with postoperative scores ranging from 59.2 to 94.6 (SMD 1.66; 95% CI 1.33-1.98, P < .00001). Seven studies reported significant improvement in Nonarthritic Hip Score with postoperative scores ranging from 79.6 to 95.3 (SMD 1.41; 95% CI 1.16-1.65, P < .00001). Seven studies also reported significant improvement in VAS with postoperative scores ranging from 0.7 to 3.1 (SMD -1.57; 95% CI -1.88, -1.26, P < .00001). Nine of 10 studies reported achieving at least 1 psychometric threshold at a rate of least 75%. Rates of secondary arthroscopy and conversion to total hip arthroplasty varied from 0% to 15.2% and 0% to 33.3%. CONCLUSIONS Athletes who underwent primary hip arthroscopy demonstrated favorable outcomes and high rates of clinical benefit at 5-year follow-up. In addition, they demonstrated high rates of survivorship and achieving psychometric thresholds. LEVEL OF EVIDENCE Level IV, systematic review of Level III and IV studies.

Abstract
PURPOSE (1) To evaluate minimum 10-year PROs (patient-reported outcomes) and survivorship after primary hip arthroscopy and (2) to identify predictors of failure for secondary arthroscopy and conversion to total hip arthroplasty (THA). METHODS A systematic review of the literature was conducted with the following key words: "hip arthroscopy," "long-term," "outcomes," "ten-year," "survivorship," "10-year," "15-year," "fifteen-year," 20-year," "twenty-year," and "femoroacetabular impingement" in PubMed and Embase in March 2022 using the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. Level I to Level IV evidence was included and reported on minimum 10-year outcomes or greater after primary hip arthroscopy. Long-term studies were defined as minimum 10-year follow-up in accordance with established standards in the literature. Case reports, review articles, technique articles, and opinion articles were excluded. Articles not in English were excluded. Title, author, publication date, study design, demographic, number of hips, follow-up time, study period, indications for hip arthroscopy, PROs, predictors of failure for THA, and rates of secondary surgeries were recorded. Survivorship was defined as a nonconversion to THA. P < .05 was defined as statistical significance. RESULTS Twelve studies met the inclusion criteria. In total, 4 studies were Level III, and 8 studies were Level IV. A total of 1,344 hips were included, and follow-up ranged from 10 to 20 years. Femoroacetabular impingement syndrome was the most common indication for hip arthroscopy. Ten of the 12 studies reported on PROs, and 8 studies reported significant improvement after hip arthroscopy at long-term follow-up. The remaining 2 studies reported favorable outcomes that satisfied clinical benefit thresholds at minimum 10-year follow-up. Five studies reported clinical benefit where each patient cohort achieved 80% minimal clinically important difference and 75% patient acceptable symptomatic state for at least one PRO. Rates of secondary arthroscopy ranged from 4.5% to 24%, and rates of conversion to THA varied from 0% to 44.1%. Older age and chondral damage were the most commonly cited predictors for conversion to THA. CONCLUSIONS At long-term follow-up, patients who underwent primary hip arthroscopy demonstrated favorable outcomes and variable rates of secondary surgeries. Patients undergoing hip arthroscopy within the last 20 years with Tönnis grade <1 and labral repair experienced greater than 90% survivorship. Chondral damage and older age were the most cited predictors for conversion to THA. LEVEL OF EVIDENCE Level IV, systematic review of Level III and Level IV studies.

Hip Arthroscopy in the Presence of Advanced Osteoarthritis Results in 57% Survivorship, With 78% Survivor Satisfaction, at 10 Years. A Matched-Control Study. Arthroscopy 2023; 39:256-268. [PMID: 35995331 DOI: 10.1016/j.arthro.2022.07.022] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/14/2021] [Revised: 07/27/2022] [Accepted: 07/28/2022] [Indexed: 02/02/2023]
Abstract
PURPOSE To (1) determine the 10-year survivorship (avoidance of total hip arthroplasty, THA) for patients with advanced osteoarthritis (OA) undergoing hip arthroscopy for femoroacetabular impingement, and (2) compare survivorship and patient-reported outcomes (PROs) with a matched-control group without OA. METHODS Advanced OA hips (Tönnis ≥2) were matched in a 1:1 ratio (age ± 5 years, sex) to hips with preoperative Tönnis grade ≤1. Exclusion criteria was dysplasia, age <18 years, previous hip conditions/surgeries, and bilaterally operated patients with OA on one side only. Survival was estimated by Kaplan-Meier analysis for levels of sex, age groups and Tönnis. Cox proportional hazards model estimated hazard ratios (HR) of undergoing THA conversion. Where THA was avoided, outcomes and proportion of cases achieving patient acceptable symptomatic state was determined RESULTS: 53 OA hips were matched with 53 control hips. Survival distributions were significantly different for: (1) Group: OA 57.1%, control 87.0% (P = .001); (2) Tönnis grade: Tönnis 0, 89.2%; Tönnis 1, 77.8%; Tönnis 2, 67.6%; Tönnis 3, 25.0% (P < .001); and (3) age: (OA: 75.0% vs 44.8%, control: 100%, vs 75.0%, for <35 and >35 years respectively) (P = .002). Conversion to THA was greater for increasing Tönnis: HR 1.9 (P = .450), 3.5 (P = .032), and 11.0 (P < .001) for Tönnis 1, 2, and 3 respectively, relative to no OA (Tönnis 0) and >35 years: HR 4.3 (95% confidence interval 1.6-11.3, P = .003). Patient acceptable symptomatic state achievement was similar for both groups (78% OA vs 91% control, P = .167). modified Harris Hip Score and Short Form-36 significantly improved within both groups from baseline to 10 years CONCLUSIONS: Arthroscopic correction of femoroacetabular impingement, in the presence of advanced OA results in 57% survivorship at 10 years (68% Tönnis 2, 25% Tönnis 3). Where THA was avoided, 78% considered their 10-year post-HA state to be satisfactory, with patient-reported outcomes similar to a matched non-OA cohort. Tönnis 2 in particular should be considered for arthroscopic hip preservation to avoid the need to prematurely replace the hip joint. LEVEL OF EVIDENCE IV, case series.

Abstract
Background The most common surgical approaches in hip arthroscopy are interportal and T-capsulotomy. However, these methods may introduce capsular instability. Puncture capsulotomy preserves capsuloligamentous integrity by avoiding iatrogenic transection of the iliofemoral capsular ligament. Purpose To present minimum 2-year functional outcomes for patients who underwent arthroscopic treatment for acetabular labral tears and concomitant femoroacetabular impingement using the puncture capsulotomy technique. Study Design Case series; Level of evidence, 4. Methods The authors conducted a retrospective review of prospectively collected data on patients who underwent arthroscopic acetabular labral tear treatment between December 2013 and May 2019. Included were patients aged ≥18 years who underwent hip arthroscopy by a single surgeon and completed a minimum of 2 years of patient-reported outcome measure (PROM) surveys. Intraoperatively, patients underwent hip arthroscopy via puncture capsulotomy to treat labral tears and any concomitant femoroacetabular impingement. Clinical outcome data consisted of PROMs. Results A total of 163 hips were included; the mean patient follow-up was 30.4 months (range, 24-60 months; 95% CI, 28.5-32.3 months). Patients had a mean age of 37.9 years (range, 36.1-39.6 years), with a mean body mass index of 25.9 (range, 25.2-26.5). There were significant improvements in mean [95% CI] baseline to final follow-up scores for the 33-Item International Hip Outcome Tool (iHOT-33) (39.6 [36.8-42.4] vs 76.1 [72.7-79.6]), Hip Outcome Score-Activities of Daily Living (70.0 [67.0-73.0] vs 89.3 [87.3-91.3]), modified Harris Hip Score (60.1 [57.9-62.4] vs 84.9 [82.5-87.2]), and Hip Outcome Score-Sports Specific Subscale (41.8 [37.9-45.6] vs 75.7 [71.7-79.7]) (P < .001 for all). Additionally, the mean [95% CI] visual analog scale pain scores were noted to significantly improve throughout the duration of the postoperative period (from 6.3 [5.9-6.7] to 2.2 [1.8-2.6]; P < .001). There were no incidences of infection, avascular necrosis of the femoral head, dislocation/instability, or femoral neck fracture. At the 2-year follow-up, 81.0%, 62.0%, and 58.9% of hips achieved previously published clinically meaningful iHOT-33 thresholds for minimally clinically important difference, Patient Acceptable Symptom Score, and substantial clinical benefit, respectively. Conclusion Puncture capsulotomy demonstrated significantly improved functional and clinically meaningful outcomes at a minimum 2-year follow-up, along with a minimal complication rate.

Hip arthroscopy for femoroacetabular impingement is associated with significant improvement in early patient reported outcomes: analysis of 4963 cases from the UK non-arthroplasty registry (NAHR) dataset. Knee Surg Sports Traumatol Arthrosc 2023; 31:58-69. [PMID: 35833961 PMCID: PMC9859857 DOI: 10.1007/s00167-022-07042-y] [Citation(s) in RCA: 16] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/21/2021] [Accepted: 06/09/2022] [Indexed: 01/25/2023]
Abstract
PURPOSE Results from recent randomised controlled trials demonstrate the superiority of surgery over physiotherapy in patients with femoroacetabular impingement (FAI) of the hip in early follow-up. However, there is paucity of evidence regarding which factors influence outcomes of FAI surgery, particularly notable is the lack of information on the effect of impingement subtype (cam or pincer or mixed) on patient reported outcomes measures (PROMs). This study aims to evaluate the early outcomes of hip arthroscopy for FAI, and their determinants. METHODS This is a retrospective analysis of prospectively collected data from the UK Non-Arthroplasty Hip Registry (NAHR) of patients undergoing arthroscopic intervention for FAI between 2012 and 2019. The null hypothesis was that there is no difference in PROMs, based on morphological subtype of FAI treated or patient characteristics, at each follow-up timepoint. The outcome measures used for the study were the iHOT-12 score and the EQ5D Index and VAS 6- and 12-month follow-up. RESULTS A cohort of 4963 patients who underwent arthroscopic treatment of FAI were identified on the NAHR database. For all FAI pathology groups, there was significant improvement from pre-operative PROMs when compared to those at 6 and 12 months. Overall, two-thirds of patients achieved the minimum clinically important difference (MCID), and almost half achieved substantial clinical benefit (SCB) for iHOT-12 by 12 months. Pre-operatively, and at 12-month follow-up, iHOT-12 scores were significantly poorer in the pincer group compared to the cam and mixed pathology groups (p < 0.01). Multivariable analysis revealed PROMS improvement in the setting of a higher-grade cartilage lesion. CONCLUSION This registry study demonstrates that hip arthroscopy is an effective surgical treatment for patients with symptomatic FAI and results in a statistically significant improvement in PROMs which are maintained through 12 months follow-up.

Abstract
PURPOSE To define the clinical effect of intra-articular injection of iliac crest-derived bone marrow aspirate concentrate (BMAC) at the time of hip arthroscopy in patients with symptomatic labral tears and early radiographic degenerative changes. METHODS A retrospective review of a prospectively collected hip registry database was performed. Patients with symptomatic labral tears and Tönnis grade 1 or 2 degenerative changes who underwent labrum-preserving hip arthroscopy with BMAC injection were included and were matched with patients who underwent hip arthroscopy without BMAC injection. Patient-reported outcomes (PROs) collected preoperatively and up to 2 years postoperatively included the modified Harris Hip Score, Hip Outcome Score-Activities of Daily Living, Hip Outcome Score-Sport, and International Hip Outcome Tool 33 score. Clinical relevance was measured with the minimal clinically important difference, patient acceptable symptom state, and substantial clinical benefit for each outcome score. RESULTS A total of 35 patients underwent labrum-preserving hip arthroscopy with BMAC injection and were matched with 35 control patients. There were no differences in demographic characteristics between the groups (P > .05). The BMAC group consisted of 22 patients (62.9%) with Tönnis grade 1 changes and 13 (37.1%) with Tönnis grade 2 changes, whereas all 35 control patients had Tönnis grade 0 hips. All PROs were significantly improved in both groups at 2 years, with no difference in improvement. The rate of failure requiring conversion to total hip arthroplasty was 14.3% (mean, 1.6 years postoperatively) in the BMAC group and 5.7% (mean, 7 years postoperatively) in the control group (P = .09). The difference in the frequency of patients achieving the minimal clinically important difference, patient acceptable symptom state, and substantial clinical benefit was not statistically significant between cohorts. CONCLUSIONS In a challenging group of patients with symptomatic labral tears and early radiographic degenerative changes, hip arthroscopy with BMAC injection results in statistically and clinically significant improvement in PROs comparable to a group of patients with nonarthritic hips undergoing hip arthroscopy at short-term follow-up. LEVEL OF EVIDENCE Level III, retrospective comparative therapeutic trial.

J Arthroplasty 2022; 38:998-1003. [PMID: 36535446 DOI: 10.1016/j.arth.2022.12.028] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/04/2021] [Revised: 12/01/2022] [Accepted: 12/12/2022] [Indexed: 12/23/2022] Open
Abstract
BACKGROUND Conversion hip arthroplasty is defined as a patient who has had prior open or arthroscopic hip surgery with or without retained hardware that is removed and replaced with arthroplasty components. Currently, it is classified under the same diagnosis-related group as primary total hip arthroplasty (THA); however, it frequently requires a higher cost of care. METHODS A retrospective study of 228 conversion THA procedures in an orthopaedic specialty hospital was performed. Propensity score matching was used to compare the study group to a cohort of 510 primary THA patients by age, body mass index, sex, and American Society of Anesthesiologists score. These matched groups were compared based on total costs, implants used, operative times, length of stay (LOS), readmissions, and complications. RESULTS Conversion THA incurred 25% more mean total costs compared to primary THA (P < .05), longer lengths of surgery (154 versus 122 minutes), and hospital LOS (2.1 versus 1.56 days). A subgroup analysis showed a 57% increased cost for cephalomedullary nail conversion, 34% increased cost for sliding hip screw, 33% for acetabular open reduction and internal fixation conversion, and 10% increased costs in closed reduction and percutaneous pinning conversions (all P < .05). There were 5 intraoperative complications in the conversion group versus none in the primary THA group (P < .01), with no statistically significant difference in readmissions. CONCLUSION Conversion THA is significantly more costly than primary THA and has longer surgical times and greater LOS. Specifically, conversion THA with retained implants had the greatest impact on cost.

Abstract
PURPOSE To report minimum 10-year follow-up survivorship, defined as non-conversion to total hip arthroplasty (THA), and patient-reported outcome scores (PROS) after primary hip arthroscopy with acetabular microfracture in the setting of femoroacetabular impingement syndrome (FAIS) and acetabular chondral lesions, respectively. METHODS Data were prospectively collected and retrospectively analyzed on all patients who underwent a primary hip arthroscopy and received an acetabular microfracture between June 2009 and January 2011. Patients with a minimum 10-year follow-up for the modified Harris Hip Score (mHHS), Nonarthritic Hip Score (NAHS), and the visual analog scale (VAS) for pain were included. If available, the minimum 10-year follow-up for the Hip Outcome Score-Sport-Specific Subscale was reported. The demographics, intraoperative findings, surgical procedures, PROS, rate of achieving the minimal clinical important difference (MCID), and secondary surgeries were analyzed and reported. RESULTS Twenty-two hips (20 patients) were included in the study, and the mean follow-up time was 124.5 ± 2.2 months. There were 17 hips (77.3%) from males and 5 hips (22.7%) from females. The average patient age at the time of surgery was 42.3 years ± 9.6. All patients on average experienced statistically significant improvement (P < .05) between preoperative and minimum 10-year follow-up scores for all PROs. In total, 77.3% of the patients did not require conversion to THA. Additionally, 83.3% of the patients achieved the MCID for the mHHS, NAHS, and VAS for pain. CONCLUSION At a minimum 10-year follow-up, survivorship of 77.3% was reported for patients who underwent primary hip arthroscopy with acetabular microfracture for the treatment of FAIS and focal/full-thickness acetabular cartilage lesions. Further, in the patients that did not require THA conversion, significant improvement in all PROS was demonstrated. LEVEL OF EVIDENCE IV, case-series study.

Abstract
Labral calcification may be part of the natural history of untreated femoroacetabular impingement syndrome (FAIS) in certain patients, making it a potential target for intervention with the goal of preserving the hip joint. The purpose of this study was to investigate if calcified labra create the appearance of lateral joint space narrowing and report minimum 2-year patient-reported outcome measures (PROMs) after treating patients with arthroscopic acetabuloplasty and labral reconstruction. Prospectively collected data on patients who underwent primary hip arthroscopy for FAIS and labral tearing from February 2015 to April 2021 were reviewed. Patients treated with primary labral reconstruction for an intraoperatively confirmed diagnosis of labral calcification were included. A sub-analysis was performed for patients with a minimum of 2-year follow-up. Preoperative and postoperative PROMs for the modified Harris hip score, nonarthritic hip score, the International Hip Outcome Tool-12 and visual analog scale for pain were recorded. Forty-six hips (46 patients) were included, with 19 hips in the sub-analysis. There was a significant increase in apparent lateral joint space width (JSW) measured on supine anteroposterior (AP) pelvis radiographs with no significant changes in medial and central JSW and significant decreases in the lateral and anterior center-edge angles and alpha angle. Patients experienced significant increases in PROMs and high rates of achieving psychometric thresholds. Patients presenting with FAIS and calcified labra may have apparent lateral joint space narrowing on pre-operative supine AP pelvis radiographs. These patients have low rates of full-thickness femoral head and acetabular cartilage pathology, this apparent narrowing can be corrected and excellent outcomes and survivorship can be achieved, with primary labral reconstruction.

Abstract
PURPOSE To measure and compare the torque to failure and stiffness of the capsular repair construct consisting of four-suture simple stitches to a two-figure of eight stitches repair construct in external rotation following an interportal capsulotomy. METHODS Six pairs of fresh-frozen cadaveric hemipelves were divided into two capsular repair groups. All hips underwent a 40-mm interportal capsulotomy from the 12 o'clock position to the 3 o'clock position. Capsular closure was performed using either the two stitches in a figure of eight or with four simple stitches. Afterward, each hemipelvis was securely fixed to the frame of a mechanical testing system with the hip in 10° of extension and externally rotated to failure. Significance was set at P < .05. RESULTS The average failure torque was 86.2 ± 18.9 N·m and 81.5 ± 8.9 N·m (P = .57) for the two stitches in a figure of eight and the four simple stitches, respectively. Failure stiffness was also not statistically different between groups and both capsular closure techniques failed at similar degrees of rotation (P = .65). CONCLUSION Hip capsular repair using either the four simple stitch or two-figure of eight configurations following interportal capsulotomy demonstrated comparable failure torques and similar stiffness in a cadaveric model. CLINICAL RELEVANCE Adequate and comprehensive capsular management in hip arthroscopy is critical. Capsular repair following capsulotomy in femoroacetabular impingement surgery has been associated with higher patient-reported outcomes when compared to capsulotomy without repair. Therefore, determining which capsular closure construct provides the higher failure torque is important.

Abstract
BACKGROUND Although femoral osteoplasty is common practice in treating cam-type femoroacetabular impingement (FAI), long-term data are lacking that support the ability of this procedure to optimize outcomes and alter natural history. PURPOSE To compare long-term clinical outcomes and survivorship of treatment for symptomatic FAI via arthroscopic correction of labral or chondral pathology with and without femoral osteoplasty. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS A retrospective cohort study was performed across 2 consecutive cohorts of patients with isolated cam-type FAI who underwent hip arthroscopic treatment of labral or chondral pathology without femoral osteoplasty (HS group) or with femoral osteoplasty (HS-OST group). These unique cohorts were established at a distinct transition time in our practice before and after adoption of femoral osteoplasty for treatment of FAI. Clinical outcomes were measured using the modified Harris Hip Score (mHHS). Kaplan-Meier analysis was used to assess for total hip arthroplasty (THA)-free and reoperation-free survivorship. RESULTS The final HS group included 17 hips followed for 19.7 ± 1.2 years, and the final HS-OST group included 23 hips followed for 16.0 ± 0.6 years. No significant patient or morphological differences were found between groups. Compared with the HS group, the HS-OST group had significantly higher final mHHS (82.7 vs 64.7 for HS-OST vs HS, respectively; P = .002) and mHHS improvement (18.4 vs 6.1; P = .02). The HS-OST group also had significantly greater 15-year THA-free survivorship versus the HS group (78% vs 41%, respectively; P = .02) and reoperation-free survivorship (78% vs 29%; P = .003). CONCLUSION This study demonstrated superior long-term clinical outcomes and survivorship with combined arthroscopy and femoral osteoplasty compared with hip arthroscopy alone. These long-term data strongly support the practice of femoral osteoplasty in patients with cam FAI morphologies and suggest that this treatment alters the natural history of FAI at long-term follow-up.

Abstract
Aims The primary aim of this study was to determine the ten-year outcome following surgical treatment for femoroacetabular impingement (FAI). We assessed whether the evolution of practice from open to arthroscopic techniques influenced outcomes and tested whether any patient, radiological, or surgical factors were associated with outcome. Methods Prospectively collected data of a consecutive single-surgeon cohort, operated for FAI between January 2005 and January 2015, were retrospectively studied. The cohort comprised 393 hips (365 patients; 71% male (n = 278)), with a mean age of 34.5 years (SD 10.0). Over the study period, techniques evolved from open surgical dislocation (n = 94) to a combined arthroscopy-Hueter technique (HA + Hueter; n = 61) to a pure arthroscopic technique (HA; n = 238). Outcome measures of interest included modes of failures, complications, reoperation, and patient-reported outcome measures (PROMs). Demographic, radiological, and surgical factors were tested for possible association with outcome. Results At a mean follow-up of 7.5 years (SD 2.5), there were 43 failures in 38 hips (9.7%), with 35 hips (8.9%) having one failure mode, one hip (0.25%) having two failure modes, and two hips (0.5%) having three failure modes. The five- and ten-year hip joint preservation rates were 94.1% (SD 1.2%; 95% confidence interval (CI) 91.8 to 96.4) and 90.4% (SD 1.7%; 95% CI 87.1 to 93.7), respectively. Inferior survivorship was detected in the surgical dislocation group. Age at surgery, Tönnis grade, cartilage damage, and absence of rim-trimming were associated with improved preservation rates. Only Tönnis grade was an independent predictor of hip preservation. All PROMs improved postoperatively. Factors associated with improvement in PROMs included higher lateral centre-edge and α angles, and lower retroversion index and BMI. Conclusion FAI surgery provides lasting improvement in function and a joint preservation rate of 90.4% at ten years. The evolution of practice was not associated with inferior outcome. Since degree of arthritis is the primary predictor of outcome, improved awareness and screening may lead to prompt intervention and better outcomes.

Ultrasound Demonstrates Potential in Identify Proximal Femoral Morphology Before and After Cam Resection: A Cadaveric Study. Arthroscopy 2022; 39:751-757.e2. [PMID: 37194110 DOI: 10.1016/j.arthro.2022.10.015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/02/2021] [Revised: 09/25/2022] [Accepted: 10/10/2022] [Indexed: 11/09/2022]
Abstract
PURPOSE (1) To compare alpha angles measured on fluoroscopy with those measured on ultrasound pre- and postosteoplasty and (2) to determine whether ultrasound can adequately assess cam deformity correction. METHODS Twelve full-body specimens (20 hips) were analyzed. Images using fluoroscopy and ultrasound were captured of the operative hip with the hip in 6 consistent positions: 3 views in hip extension (neutral [N], 30° internal rotation [IR], and 30° external rotation [ER]) and 3 views in hip flexion of 50° (neutral [F-N], 40° external rotation [F-ER40], and 60° external rotation [F-ER60]). A curved-array ultrasound transducer probe was used with the transducer placed in line with the femoral neck to evaluate the proximal femoral morphology. An open femoral osteoplasty using an anterior approach was performed. Fluoroscopy and ultrasound were again used to capture images with the hip in the same 6 positions. Bland-Altman plots were used to determine whether fluoroscopic and ultrasound alpha angles agreed at each position. Independent t-tests were used to compare the alpha angles between the 2 modalities at each position, and paired t-tests were used to compare preoperative and postoperative alpha angles at each position. RESULTS No significant differences between the alpha angle on fluoroscopy and ultrasound at all 6 positions were appreciated preosteoplasty. The mean preoperative alpha angle on ultrasound in each position was as follows: N (55.4° ± 5.9° vs 43.0° ± 2.1°), IR (55.1° ± 5.3° vs 43.9° ± 5.5°), ER (58.6° ± 5.6° vs 42.8° ± 3.0°), F-N (53.9° ± 5.5° vs 41.6° ± 3.3°), F-ER40 (55.5° ± 4.6° vs 41.5° ± 2.7°), and F-ER60 (57.9° ± 6.5° vs 41.2° ± 4.2°). The mean preoperative and postoperative alpha angle on fluoroscopy in each position were as follows: N (56.0 ± 12.8° vs 43.1 ± 2.1°), IR (54.1 ± 13.4° vs 41.9 ± 2.9°), ER (61.2 ± 11.0° vs 44.2 ± 1.9°), F-N (57.9 ± 10.6° vs 44.0 ± 2.3°), F-ER40 (59 ± 8.2° vs 42 ± 2.2°), and F-ER60 (55 ± 7.6° vs 41.1 ± 2.6°). Postosteoplasty, there was no significant difference between the mean alpha angle on fluoroscopy versus ultrasound in any position except F-N (44.0 ± 2.3 vs 41.6 ± 3.3, P = .015). Bland-Altman plots showed a high level of agreement between alpha angle values on fluoroscopy and ultrasound at all positions pre- and postosteoplasty. There was a significant reduction in alpha angle measured on ultrasound and fluoroscopy at each position following osteoplasty. There were no significant differences in the delta of the pre- and postosteoplasty alpha angle measurements between fluoroscopy and ultrasound. CONCLUSIONS Ultrasound is a useful tool for assessing a cam deformity in patients with femoroacetabular impingement syndrome and for determining adequate resection of a cam deformity intraoperatively. CLINICAL RELEVANCE Due to the inherent limitations and risks of the fluoroscopy, it is worth evaluating other nonionizing imaging modalities. Ultrasound has potential to be an accessible, cost-effective, and safe imaging modality that lacks radiation and is commonly used for intra-articular hip injections and dynamic examination of the hip.

Abstract
BACKGROUND While labral repair has been widely adopted as the first line treatment for labral injury during hip arthroscopy, there is no widespread consensus on the procedural technique, including the number of anchors that should be used to avoid recurrent instability and revision surgery. PURPOSE To determine if anchor density can predict patient-reported outcomes after arthroscopic labral repair in the hip. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Patients aged 18 to 50 years who underwent primary hip arthroscopic surgery with labral repair between January 2011 and December 2016 were identified from a prospectively collected database. Exclusion criteria consisted of previous ipsilateral surgery, osteoarthritis (Tönnis grade >1), and severe cartilage defects (Outerbridge grade III/IV) or concomitant labral reconstruction, capsular reconstruction, or microfracture. Minimum 2-year patient-reported outcomes (modified Harris Hip Score [mHHS], Hip Outcome Score [HOS]-Activities of Daily Living [ADL], HOS-Sport Specific Subscale [SSS], 12-Item Short Form Health Survey [SF-12]), rates of achieving the minimal clinically important difference (MCID) and patient acceptable symptom state (PASS) for each score, revision surgery rate, and rate of conversion to total hip arthroplasty (THA) were compared based on anchor density (number of anchors per millimeter of labral tear). RESULTS A total of 634 hips (575 patients) with a mean age of 30.4 ± 9.5 years (range, 18.0-49.9 years) met inclusion criteria. The mean labral tear size was 31 ± 11 mm (range, 2-70 mm) with a median number of anchors used for labral repair of 3 (range, 1-7) and mean anchor density of 0.11 ± 0.08 anchors (range, 0.03-1.33) per millimeter of labral tear. Hips with a minimum 2-year follow-up (451/634 [71.1%]) had significant improvements on the mHHS, HOS-ADL, HOS-SSS, and SF-12 Physical Component Summary (P < .001 for all). There was no significant correlation detected between anchor density or number of anchors used and postoperative scores (correlation coefficient range, -0.05 to 0.17; P > .05 for all). The rate of revision surgery was 6.4% (28 patients), with 8 hips found to have labral tears and/or deficiency on revision. Additionally, 6 hips (1.3%) had to undergo THA at a mean of 3.6 ± 2.1 years (range, 2.0-5.5 years). CONCLUSION Anchor density did not have a correlation with postoperative outcomes, achieving the MCID or PASS, revision hip arthroscopic surgery, complications, or conversion to THA.

Abstract
To determine whether the presence of spine pathology affects clinical outcomes after hip arthroscopy for femoroacetabular impingement syndrome (FAIS) in the setting of hip-spine syndrome (HSS) METHODS: A systematic review of PubMed and Cochrane was conducted. Primary research articles evaluating patient-reported outcomes (PRO) after hip arthroscopy for FAIS in the presence of concomitant spine pathology were considered RESULTS: Literature review identified 12 studies meeting criteria. In 2109 FAIS patients undergoing hip arthroscopy, 591 had concomitant spine pathology. Baseline PROs in the hip-spine (modified Harris Hip Score [mHHS]: 39.8-65.29 vs 56.9-78.8, 8 studies; non-arthritic hip score [NAHS]: 42.2-51.5 vs 68.2-75.2, 4 studies; hip outcome score-activities of daily living [HOS-ADL]: 45.9-71.1 vs 49.3-89.51, 9 studies; hip outcome score-Sport (HOS-Sport): 22.8-49.6 vs 50.6-73.1, 3 studies; international hip outcome tool-33 [iHOT-12]: 38.0 vs 66.0, 1 study; visual analog scale [VAS] Pain: 6.43-6.56 vs 1.18-3.60, 3 studies; VAS Satisfaction: 7.18-7.46 range at follow-up, 2 studies) and control (mHHS: 39.3-64.9 vs 70.2-92.6, 6 studies; NAHS: 42.8-54.2 vs 74.0-87.1, 4 studies; HOS-ADL: 59.0-76.4 vs 75.4-97.1, 4 studies; HOS-Sport: 38.1-55.1 vs 60.9-93.9, 3 studies; iHOT-12: 43.4 vs 89.8, 1 study; VAS Pain: 6.18-6.22 vs 1.82-3.44, 2 studies; VAS Satisfaction: 7.74-8.22 range at follow up, 2 studies). Minimal clinically important difference threshold rates achieved in the hip-spine (44.1-86.7, 4 studies) cohorts were significantly lower than control (79.4-88.2%; 4 studies) cohorts in 3 studies. Patient-acceptable symptomatic state threshold rates achieved in the hip-spine (42-63.5, 3 studies) cohorts were significantly lower than control (58.8-81.0, 3 studies) in 1 study. There was no statistical difference in complication and reoperation rates between cohorts CONCLUSION: FAIS patients with concomitant HSS have improved but inferior outcomes after hip arthroscopy compared to patients without HSS LEVEL OF EVIDENCE: IV, systematic review.

Automated quantification of cartilage quality for hip treatment decision support. Int J Comput Assist Radiol Surg 2022; 17:2011-2021.

Abstract
Purpose Preservation surgery can halt the progress of joint degradation, preserving the life of the hip; however, outcome depends on the existing cartilage quality. Biochemical analysis of the hip cartilage utilizing MRI sequences such as delayed gadolinium-enhanced MRI of cartilage (dGEMRIC), in addition to morphological analysis, can be used to detect early signs of cartilage degradation. However, a complete, accurate 3D analysis of the cartilage regions and layers is currently not possible due to a lack of diagnostic tools. Methods A system for the efficient automatic parametrization of the 3D hip cartilage was developed. 2D U-nets were trained on manually annotated dual-flip angle (DFA) dGEMRIC for femoral head localization and cartilage segmentation. A fully automated cartilage sectioning pipeline for analysis of central and peripheral regions, femoral-acetabular layers, and a variable number of section slices, was developed along with functionality for the automatic calculation of dGEMRIC index, thickness, surface area, and volume. Results The trained networks locate the femoral head and segment the cartilage with a Dice similarity coefficient of 88 ± 3 and 83 ± 4% on DFA and magnetization-prepared 2 rapid gradient-echo (MP2RAGE) dGEMRIC, respectively. A completely automatic cartilage analysis was performed in 18s, and no significant difference for average dGEMRIC index, volume, surface area, and thickness calculated on manual and automatic segmentation was observed. Conclusion An application for the 3D analysis of hip cartilage was developed for the automated detection of subtle morphological and biochemical signs of cartilage degradation in prognostic studies and clinical diagnosis. The segmentation network achieved a 4-time increase in processing speed without loss of segmentation accuracy on both normal and deformed anatomy, enabling accurate parametrization. Retraining of the networks with the promising MP2RAGE protocol would enable analysis without the need for B1 inhomogeneity correction in the future.

Platelet-Rich Plasma Is Not Associated With Improved Outcomes Following Hip Femoroacetabular Impingement Surgery: Very Low-Quality Evidence Suggests Hyaluronic Acid and Cell-Based Therapies May Be Beneficial—A Systematic Review of Biological Treatments. Arthrosc Sports Med Rehabil 2022; 4:e1557-e1573.

Abstract
Purpose To examine the efficacy of biologic agents in the treatment of cartilage defects associated with femoroacetabular impingement (FAI). Methods PubMed, Ovid MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, and the Cochrane Database of Systematic Reviews were reviewed by 2 independent reviewers for eligible studies. We included randomized and nonrandomized control trials as well as uncontrolled case series and retrospective studies. Studies were excluded if they included injections of corticosteroids, papers that described technique only, review papers, and those not in the English language. Demographics, treatment type, outcome of treatment, and complications were extracted, whereas risk of bias and study quality were assessed independently using the risk of bias tool (ROB2) and effective public health practice project tool. A narrative synthesis was performed, and standardized mean differences were reported. Certainty of evidence was assessed using the GRADE approach. Results Eighteen studies consisting of 1,024 patients met the inclusion criteria. Three studies involved the use of platelet-rich plasma (PRP) as an adjuvant to surgery and were included in the meta-analysis. Three studies administered hyaluronic acid (HA) as a primary treatment. Twelve involved various cell-based methods of chondrocyte stimulation for cartilage defects associated with FAI, but heterogeneity did not allow for pooling. Low-quality evidence indicates PRP is not associated with improved outcomes following surgery (mean difference –1.42, 95% confidence interval –3.95 to 1.11, P = .27). Very-low-quality evidence suggests HA (standardized mean difference 1.15, 95% confidence interval 0.64-1.66, P < .001, Z = 4.39) and cell-based therapies may improve function and pain in patients with FAI. Conclusions Low-quality evidence indicates PRP is not associated with improved outcomes following hip FAI surgery, and very-low-quality evidence suggests HA and cell-based therapies may improve outcomes. Level of Evidence systematic review of Level I-V studies.

Younger Age, Capsular Repair, and Larger Preoperative Alpha Angles Are Associated With Earlier Achievement of Clinically Meaningful Improvement After Hip Arthroscopy for Femoroacetabular Impingement Syndrome. Arthroscopy 2022; 38:2195-2203. [PMID: 34920008 DOI: 10.1016/j.arthro.2021.12.007] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/19/2021] [Revised: 11/30/2021] [Accepted: 12/01/2021] [Indexed: 02/02/2023]
Abstract
PURPOSE The purpose of the study was to analyze demographic, radiographic, and intraoperative factors that influence the time to achieve the minimal clinically important difference (MCID) and maximum outcome improvement satisfaction threshold (MOIT) after primary hip arthroscopy for femoroacetabular impingement syndrome (FAIS) and labral tear. METHODS Included patients had undergone hip arthroscopy with labral repair or reconstruction for FAIS with labral tear between February 2008 and October 2018. Patients were excluded if they had a prior ipsilateral hip surgery, prior hip conditions, a Tonnis grade > 1, or were unwilling to participate. Multiple demographic, radiographic, and intraoperative variables were collected. The modified Harris Hip Score (mHHS) and Non-Arthritic Hip Score (NAHS) were collected before surgery and at 3 months, 1 year, and 2 years after surgery. The MCID and MOIT for the mHHS and NAHS were either calculated or determined through previously published values. A time-to-event analysis was performed to determine variables predictive of early or delayed achievement of MCID or MOIT. Early achievement was defined as achieving MCID or MOIT at the 3-month timepoint. RESULTS Six hundred thirty-two hips (632 patients) were included. Of those that achieved MCID and MOIT, 428 (73.0%) and 414 (73.0%) patients achieved MCID and 253 (47.9%) and 264 (52.5%) patients achieved MOIT by 3 months after surgery for mHHS and NAHS, respectively. Younger age, capsular repair, and increasing alpha angle were associated with earlier achievement for either MCID or MOIT. Increasing age, worker's compensation claims, and higher baseline patient-reported outcome measure scores were associated with delayed achievement for either MCID or MOIT. CONCLUSIONS Most of the patients who achieved MCID and MOIT for mHHS and NAHS did so by 3 months after surgery. Younger age, capsular repair, and increasing alpha angle were associated with earlier achievement of MCID and MOIT after hip arthroscopy. LEVEL OF EVIDENCE Level IV, case series.

Orthop J Sports Med 2022; 10:23259671221109012. [PMID: 35837442 PMCID: PMC9274418 DOI: 10.1177/23259671221109012] [Citation(s) in RCA: 30] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/21/2022] [Accepted: 05/26/2022] [Indexed: 11/17/2022] Open
Abstract
Background: Arthroscopic treatment for labral tears includes debridement and repair.
Long-term studies have failed to demonstrate a difference between these
treatments in terms of conversion to total hip arthroplasty (THA). Purpose: To investigate 2 different labral treatments, debridement and repair, using
an adjusted analysis to evaluate long-term conversion to THA. Study Design: Cohort study; Level of evidence, 3. Methods: This was a retrospective cohort study of patients who underwent hip
arthroscopy by a single surgeon between April 2007 and October 2014.
Postoperative follow-up information included conversion to THA, patient
satisfaction, and patient-reported outcome measures (modified Harris Hip
Score; Hip Outcome Score, Activities of Daily Living and Sports Specific
subscales; International Hip Outcome Tool; Nonarthritic Hip Score; and Lower
Extremity Functional Scale). Results: Of the 204 hips included in the study, 99 (48.5%) underwent labral repair,
and 105 (51.5%) underwent debridement. In total, 28 (13.7%) of the 204
patients underwent conversion to THA within 10 years after hip arthroscopy
(labral repair: 5 [5.0%] vs labral debridement: 23 [21.9%]). Labral repair
was associated with a significantly lower risk of conversion to THA compared
with debridement (hazard ratio [HR] = 0.24; 95% CI, 0.07-0.74;
P = .014). Additional factors associated with risk of
conversion to THA included older age at the time of arthroscopy (HR = 1.06
per year; 95% CI, 1.02-1.11; P = .002) and Tönnis grade (HR
= 2.39; CI, 1.14-5.41; P = .026). Abrasion chondroplasty,
acetabuloplasty, body mass index, Outerbridge grade, and radiographic
femoroacetabular impingement were not found to be significantly associated
with risk of THA. No significant difference in patient satisfaction was
found between treatment groups, and for patients who did not convert to THA,
there was no difference in mean patient-reported outcome scores at final
follow-up. Conclusion: Patients who underwent labral repair were less likely to convert to THA
compared with patients who underwent labral debridement, despite adjustment
for differences in baseline patient characteristics and preexisting
pathology. Additional factors associated with a lower rate of hip survival
were older age and osteoarthritis at the time of hip arthroscopy.
