Abstract
Aims Hip arthroscopy has gained prominence as a primary surgical intervention for symptomatic femoroacetabular impingement (FAI). This study aimed to identify radiological features, and their combinations, that predict the outcome of hip arthroscopy for FAI. Methods A prognostic cross-sectional cohort study was conducted involving patients from a single centre who underwent hip arthroscopy between January 2013 and April 2021. Radiological metrics measured on conventional radiographs and magnetic resonance arthrography were systematically assessed. The study analyzed the relationship between these metrics and complication rates, revision rates, and patient-reported outcomes. Results Out of 810 identified hip arthroscopies, 359 hips were included in the study. Radiological risk factors associated with unsatisfactory outcomes after cam resection included a dysplastic posterior wall, Tönnis grade 2 or higher, and over-correction of the α angle. The presence of acetabular retroversion and dysplasia were also significant predictors for worse surgical outcomes. Notably, over-correction of both cam and pincer deformities resulted in poorer outcomes than under-correction. Conclusion We recommend caution in performing hip arthroscopy in patients who have three positive acetabular retroversion signs. Acetabular dysplasia with a lateral centre-edge angle of less than 20° should not be treated with isolated hip arthroscopy. Acetabular rim-trimming should be avoided in patients with borderline dysplasia, and care should be taken to avoid over-correction of a cam deformity and/or pincer deformity.

Abstract
PURPOSE To provide an updated assessment of hip arthroscopy use by using an institutional database that is specific to the treatment of femoroacetabular impingement syndrome (FAIS). METHODS All patients undergoing hip arthroscopy for the treatment of FAIS were retrospectively identified between the years 2014 and 2022 via Current Procedural Terminology coding in a multi-institutional, single health system database. A longitudinal analysis was performed to identify trends in the use of arthroscopic techniques including capsular and labral treatment, osteoplasty, and traction set-up. RESULTS During the study, 789 arthroscopic hip procedures in 733 patients were analyzed (56 staged bilateral). Between 2016 and 2022, the number of hip arthroscopies performed each year increased by 1,490% (R2 = 0.87, P = .001). Capsular repair (R2 = 0.92, P < .001), labral repair (R2 = 0.75, P = .002), and femoroplasty (R2 = 0.70, P = .004) were performed in an increasing proportion of cases over our study period whereas labral debridement (R2 = -0.84, P < .001) became less used. Postless traction systems were employed in 84% (663/789) of hip arthroscopies overall, were used in at least 70% of hip arthroscopies each year, and did not undergo any significant changes in use (R2 = 0.02, P = .73). CONCLUSIONS Capsular repair, labral repair, and femoroplasty were increasingly performed for the arthroscopic treatment of FAIS whereas the use of labral debridement decreased significantly over our study period. Postless traction systems were used in the majority of cases each year. CLINICAL RELEVANCE As comparative literature continues to define the safety and efficacy of hip arthroscopy, understanding how novel techniques or procedures are incorporated in clinical practice is important.

Arch Orthop Trauma Surg 2023; 143:6617-6629.

Abstract
INTRODUCTION Patient-Reported Outcome Measurement Information System (PROMIS) was developed as a uniform and generalizable PROM system using item response theory and computer adaptive testing. We aimed to assess the utilization of PROMIS for clinically significant outcomes (CSOs) measurements and provide insights into its use in orthopaedic research. MATERIALS AND METHODS We reviewed PROMIS CSO reports for orthopaedic procedures via PubMed, Cochrane Library, Embase, CINAHL, and Web of Science from inception to 2022, excluding abstracts and missing measurements. Bias was assessed using the Newcastle-Ottawa Scale (NOS) and questionnaire compliance. PROMIS domains, CSO measures, and study populations were described. A meta-analysis compared distribution and anchor-based MCIDs in low-bias (NOS ≥ 7) studies. RESULTS Overall, 54 publications from 2016 to 2022 were reviewed. PROMIS CSO studies were observational with increasing publication rates. Evidence-level was II in 10/54, bias low in 51/54, and compliance ≥ 86% in 46/54. Most (28/54) analysed lower extremity procedures. PROMIS domains examined Pain Function (PF) in 44/54, Pain Interference (PI) in 36/54, and Depression (D) in 18/54. Minimal clinically important difference (MCID) was reported in 51/54 and calculated based on distribution in 39/51 and anchor in 29/51. Patient acceptable symptom state (PASS), substantial clinical benefit (SCB), and minimal detectable change (MDC) were reported in ≤ 10/54. MCIDs were not significantly greater than MDCs. Anchor-based MCIDs were greater than distribution based MCIDs (standardized mean difference = 0.44, p < 0.001). CONCLUSIONS PROMIS CSOs are increasingly utilized, especially for lower extremity procedures assessing the PF, PI, and D domains using distribution-based MCID. Using more conservative anchor-based MCIDs and reporting MDCs may strengthen results. Researchers should consider unique pearls and pitfalls when assessing PROMIS CSOs.

Postoperative alpha angle seems to be important for the achievement of clinical significance at a minimum 5-year follow-up after primary hip arthroscopy. J Hip Preserv Surg 2023; 10:123-128. [PMID: 37900884 PMCID: PMC10604047 DOI: 10.1093/jhps/hnad010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/24/2022] [Revised: 02/20/2023] [Accepted: 04/08/2023] [Indexed: 10/31/2023] Open
Abstract
The purpose of the present study was to clarify whether there is an association of postoperative alpha value with functional scores or progression of osteoarthritis at X-rays at the midterm after arthroscopic treatment of femoroacetabular impingement (FAI) syndrome with femoral osteoplasty, labral repair or debridement and rim trimming. A retrospective review of prospectively gathered data from 2013 to 2017 was performed. All patients who underwent first-time unilateral hip arthroscopy for FAI resection with 5-year follow-up were included. Patient-reported outcomes included the modified Harris Hip Score (mHHS) and Visual Analog Scale for Pain (Pain VAS). The progression of osteoarthritis (Tönnis grade) and radiological parameters (alpha angle, lateral center-edge angle [LCEA] and head-neck offset) were evaluated. A receiver operating characteristic (ROC) analysis was used to evaluate the correlation between significant variables and achievement of patient-acceptable symptomatic state (PASS) and degree of osteoarthritis. We identified 52 patients with a minimum 5-year follow-up (average, 6.7 years). The average patient age was 33.9 ± 11.5 years. There were 19 (36.5%) female patients. The mHHS improved from 60.1 ± 13.4 before surgery to 86.8 ± 14 after surgery (P < 0.001). The Pain VAS decreased from 6.21 before surgery to 2 after surgery (P < 0.001). Overall, 69% achieved the PASS for mHHS. The ROC curve for postoperative alpha angle demonstrated acceptable discrimination between patients achieving a fifth-year PASS value and those who did not have an area under the curve of 0.72. Patients having a postoperative alpha angle of ≤48.3° achieved the fifth-year PASS value at a significantly higher rate than patients having a postoperative alpha angle of >48.3° (P = 0.002). The postoperative alpha angle is a predictor of the achievement of the fifth-year PASS value for the mHHS. A threshold of ≤48.3° had a sensitivity of 0.75 and a specificity of 0.69 to predict positivity. Level of evidence IV.

Patient-Reported Outcomes Measurement Information System Is Not as Responsive as Legacy Scores in Detecting Patient Outcomes in Hip Preservation: A Systematic Review. Arthroscopy 2023; 39:838-850. [PMID: 35817373 DOI: 10.1016/j.arthro.2022.06.029] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/14/2022] [Revised: 06/18/2022] [Accepted: 06/23/2022] [Indexed: 02/07/2023]
Abstract
PURPOSE To evaluate publication trends of Patient-Reported Outcomes Measurement Information System (PROMIS) in hip preservation literature, assess the usage of PROMIS as an outcome measure, and evaluate correlations of all available published PROMIS domains with legacy patient-reported outcomes (PROs). METHODS The PubMed, Scopus, Cochrane Central Register of Controlled Trials, and Google Scholar databases were queried for articles evaluating PROMIS scores among hip preservation populations. Inclusion criteria consisted of studies with Level IV evidence or above (per the Sackett et al. levels of evidence), such as case series and cohort studies, reporting on perioperative use of hip PROMIS scores. Exclusion criteria consisted of arthroplasty and trauma studies. Patient demographics, PROMIS usage, and PROMIS Pearson or Spearman correlation coefficients to historic PROs were recorded for each study. RESULTS Fifteen articles published between 2017 and 2021 were included in the analysis, with the majority (75%) published between 2020 and 2021. Studies assessing postoperative outcomes had follow-up periods ranging from 6 months to 5 years. The most common PROMIS domain reported was Physical Function (PF), and there was varying usage of other domains including Pain Intensity, Anxiety, and Depression. PROMIS validity was most often assessed in comparison to the modified Harris Hip Score (mHHS) by calculating the Pearson coefficient, which assumes normal data distribution, or Spearman coefficient, which is rank-based and does not require normal data distribution. Studies comparing PROMIS-PF with mHHS reported Pearson coefficients ranging from 0.49 to 0.72 and Spearman coefficients ranging from 0.67 to 0.71. CONCLUSIONS There has been a chronologic increase in PROMIS usage in hip preservation literature. PROMIS demonstrates moderate-to-strong correlations with legacy PROs, but there is substantial heterogeneity in follow-up periods, PROMIS domains used, and statistical methodology. The current data show that PROMIS is not as responsive as historically used, validated PROs in quantitatively assessing function and pain in hip preservation patients. CLINICAL RELEVANCE Surgeons using PROMIS solely should be aware that the score may not be as responsive as legacy PROs in closely assessing improvements or deterioration in patient performance after hip preservation surgery. Rather than being used alone, PROMIS may be useful as a replacement for a group of legacy PROs. Thus, when used alongside select legacy PROs, overall questionnaire burden can be reduced while maintaining a high level of accuracy in assessing health status.

Hip Arthroscopy for Femoroacetabular Impingement Syndrome Shows Good Outcomes and Low Revision Rates, With Young Age and Low Postoperative Pain Score Predicting Excellent 5-Year Outcomes. Arthroscopy 2023; 39:285-292. [PMID: 35367300 DOI: 10.1016/j.arthro.2022.03.024] [Citation(s) in RCA: 8] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/04/2021] [Revised: 01/16/2022] [Accepted: 03/18/2022] [Indexed: 02/02/2023]
Abstract
PURPOSE To evaluate the clinical outcomes of hip arthroscopy for femoroacetabular impingement syndrome (FAIS) and their predictors at a minimum 5 years' follow-up. METHODS We retrospectively analyzed patients with FAIS after first-time unilateral hip arthroscopy between January 2010 and July 2016. Patient-reported outcomes (PROs) included the validated modified Harries Hip Score (mHHS) and Visual Analog Scale for Pain (Pain VAS). We included patients with Tönnis grade 0 or 1 and reported PROs, and excluded patients with previous hip diseases or bilateral symptoms. Bivariate and multivariate analyses were used for data analysis. RESULTS We included 159 patients with a mean follow-up of 6.4 years, aged 36.18 ± 8.61 years, 41.5% female, and a mean body mass index of 23.61 ± 3.45. The mean postoperative mHHS was 88.82 ± 11.60, and the mean Pain VAS was 1.93 ± 1.89, significantly better than before surgery (P < .001). Postoperative alpha angle (P = .003) and lateral center edge angle (P < .001) were significantly decreased. Most patients (83.7%) achieved clinically important improvement based on patient-acceptable symptom state and minimal clinically important difference (MCID). The overall revision surgery rate was 2.5%. There were no conversions to total hip arthroplasty. Bivariate analysis indicated that age (P < .001), preoperative mHHS (P = .002), and postoperative Pain VAS (P <.001) correlated with postoperative mHHS at a minimum 5 years' follow-up. Multivariate regression analysis of MCID showed that age (P <.001), preoperative PROs (P < .01 for both), and postoperative Pain VAS (P < .001) were significant outcome predictors. CONCLUSION Patients with FAIS after first-time unilateral hip arthroscopy showed significant improvement in PROs at mid-term follow-up, with a low revision surgery rate. Young patients and those with low postoperative Pain VAS showed excellent outcomes at a minimum 5 years' follow-up. LEVEL OF EVIDENCE Level IV, retrospective case series.

Abstract
Femoro-acetabular impingement (FAI) syndrome is one of the most studied conditions in sports medicine. Surgical or conservative approaches can be proposed for treating FAI, although the best standard of care is not established yet. Our aim is to provide a comprehensive review of the best treatment for FAI syndrome evaluating differences in outcomes between surgical and non-operative management. A literature search was carried out on the PubMed, EMBASE, Scopus, and PEDro databases, using the following keywords: "femoroacetabular impingement", "FAI", in association with "surgery", "arthroscopy", "surgical" and "conservative", "physiotherapy", "physical therapy", "rehabilitation", "exercise". Only Level I RCTs were included. Four articles were selected for this systematic review. Our analysis showed different therapeutic protocols, follow-up periods, and outcomes; however, three out of the four studies included favored surgery. Our study demonstrates beneficial effects for both arthroscopic treatment and a proper regimen of physical therapy, nevertheless a surgical approach seemed to offer superior short-term results when compared to conservative care only. Further trials with larger sample sizes and longer follow-ups are needed to assess the definitive approach to the FAI condition.

Abstract
Our knowledge of appropriate arthroscopic management of femoroacetabular impingement (FAI) continues to evolve. However, few studies exist evaluating mid- to long-term surgical outcomes to guide optimal treatment. The recent focus has been on the importance of cam femoroplasty in addition to labral treatment; however, studies have shown that correction of the alpha angle to normal does not correlate with patient outcomes. Furthermore, in cases of mixed impingement, an optimal degree of acetabuloplasty as measured by the lateral center-edge angle has not been determined. Few studies have evaluated isolated pincer decompression with omission of cam treatment. In select patients with small or negligible cam lesions who do not have acetabular dysplasia, a small, isolated acetabular rim resection of 1 to 3 mm may provide adequate FAI decompression as well as reduce surgical time and complications. Nonetheless, individualized FAI treatment is necessary that includes a comprehensive 180° femoroplasty in patients with sizable cam lesions to prevent future labral and chondral damage. An intraoperative dynamic examination is important to determine sufficient resolution of FAI. Predictive modeling may play an increasingly important role to ensure appropriate bony resection and to optimize long-term patient outcomes.
