Abstract
Background: MRI utility for patients 45 years old and older with hip or knee pain is not well established. Objective: We performed this systematic review to assess whether MRI-diagnosed hip or knee pathology in patients 45 years old and older correlates with symptomatology or benefits from arthroscopic surgery. Evidence Acquisition: A literature search (PubMed, Web of Science, Embase) was performed through October 3, 2022, to identify original research pertaining to the study question. Publication information, study design, cohort size, osteoarthritis severity, age (range, mean), measured outcomes, minimum follow-up length, and MRI field strength were extracted. Study methods were appraised with NIH Quality Assessment Tools. Evidence Synthesis: The search yielded 1125 potential studies, of which 31 met inclusion criteria (18 knee, 13 hip). Knee studies (10 prospective, eight retrospective) included 5907 patients (age range, 45-90 years). Bone marrow edemalike lesions, joint effusions, and synovitis on MRI were associated with symptoms. In patients with osteoarthritis, meniscal tears were less likely to be symptom generators and were less likely to respond to arthroscopic surgery with osteoarthritis progression. Hip studies (11 retrospective, two prospective) included 6385 patients (age range, 50-85 years). Patients with Tonnis grade 2 osteoarthritis and lower with and without femoroacetabular impingement showed improved outcomes after arthroscopy, suggesting a role for MRI in the diagnosis of labral tears, chondral lesions, and femoroacetabular impingement. Although this group benefited from arthroscopic surgery, outcomes were inferior to those in younger patients. Variability in study characteristics, follow-up, and outcome measures precluded a meta-analysis. Conclusion: In patients 45 years old and older, several knee structural lesions on MRI correlated with symptoms, representing potential imaging biomarkers. Meniscal tear identification on MRI likely has diminished clinical value as osteoarthritis progresses. For the hip, MRI can play a role in the diagnosis of labral tears, chondral lesions, and femoroacetabular impingement in patients without advanced osteoarthritis. Clinical Impact: Several structural lesions on knee MRI correlating with symptoms may represent imaging biomarkers used as treatment targets. Osteoarthritis, not age, may play the greatest role in determining utility of MRI for patients 45 years old and older with hip or knee pain.

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.

High survivorship and excellent 5-year outcomes in patients older than 40 years undergoing arthroscopy for femoroacetabular impingement. Knee Surg Sports Traumatol Arthrosc 2023; 31:2123-2130. [PMID: 36912924 DOI: 10.1007/s00167-023-07369-0] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/21/2022] [Accepted: 02/24/2023] [Indexed: 03/14/2023]
Abstract
PURPOSE To assess 5-year clinical outcome, in adults > 40 years of age, following hip arthroscopy for femoroacetabular impingement compared to a younger, matched, control group. METHODS All primary arthroscopies for FAI between 2009 and 2016 were considered (n = 1762). Hips presenting with Tönnis > 1, lateral centre edge angle < 25°, or prior hip surgery were excluded. Younger (< 40 years) and older hips (> 40 years) were matched for gender, Tönnis grade, capsular repair and radiological parameters. Survival (avoidance of total hip replacement {THR}) was compared between the groups. Patient reported outcome measures (PROMs) were also completed at baseline and 5 years to assess changes in functional capacity. Additionally, hip range of motion (ROM) was assessed at baseline and review. The minimal clinically important difference (MCID) was determined and compared between groups. RESULTS Ninety-seven older hips were matched to 97 younger controls (78% male in both groups). The average age of the older group at the time of surgery was 48.0 ± 5.7 years, compared to 26.7 ± 6.0. Six (6.2%) of the older hips and 1 (1%) of younger hips converted to THR (p = 0.043, effect size = 0.74, large). There were statistically significant improvements in all PROMs. At follow-up, there were no differences in PROMs between groups; significant improvements in hip ROM were also observed with no difference in ROM between groups at either time point. Similar achievement of MCIDs was observed in both groups. CONCLUSIONS Older patients experience a high survivorship rate at 5 years, although this may be lower than younger patients. Where THR is avoided, large clinically significant improvements in pain and function are observed. LEVEL OF EVIDENCE Level IV.

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: 6] [Impact Index Per Article: 6.0] [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.

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: 10] [Impact Index Per Article: 10.0] [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.

Hip Arthroscopy Improves Outcomes With Moderate Conversion to Total Hip Arthroplasty Rates in Patients Aged 50 Years or Older: A Systematic Review. Arthroscopy 2022; 39:1539-1551.e1. [PMID: 36055478 DOI: 10.1016/j.arthro.2022.08.019] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/22/2022] [Revised: 06/10/2022] [Accepted: 08/05/2022] [Indexed: 02/02/2023]
Abstract
PURPOSE The purpose of this systematic review was to assess the indications, outcomes, and complications of hip arthroscopy in individuals 50 years of age or older over the past 5 years. METHODS The electronic databases PUBMED, MEDLINE, and EMBASE were searched on March 3, 2022, for studies assessing the use of primary hip arthroscopy for patients aged 50 years or older from the past 5 years. The Methodological Index for Non-randomized Studies (MINORS) was used to assess study quality. Data are presented descriptively. RESULTS Overall, 17 studies were included, consisting of 6,696 patients (37.5%) with a mean age of 61.4 ± 5.0 years and a median follow-up of 24 months (range: 1.4-70.1). Indications for hip arthroscopy in patients aged 50 years or older were unspecified/undefined (93.8%), mixed pathology (i.e., combined femoroacetabular impingement [FAI], labral tear, osteoarthritis, etc.) (2.7%), and FAI (2.6%). Eleven studies demonstrated significant improvement in functional outcome scores from baseline to final follow-up. Of the 6 studies that compared outcomes across multiple age groups, 3 demonstrated significantly worse functional outcomes, and 2 demonstrated significantly higher rates of conversion to THA for older patients compared to younger patients. Lastly, the overall complication rates ranged from 0 to 38.3%. The rate of conversion to THA ranged from 0 to 34.6%, occurring between 6 and 60 months postoperatively. CONCLUSIONS Hip arthroscopy for patients aged 50 years or older yields significant improvements in patient-reported outcomes postoperatively compared to baseline, with a moderate rate of conversion to THA (range: 0 to 34.6%). Clinicians should consider patient history (e.g., imaging, comorbidities, etc.) and values when electing for hip arthroscopy in the older population.

Inconclusive and Contradictory Evidence for Outcomes After Hip Arthroscopy in Patients With Femoroacetabular Impingement and Osteoarthritis of Tönnis Grade 2 or Greater: A Systematic Review. Arthroscopy 2022; 38:2307-2318.e1. [PMID: 35093497 DOI: 10.1016/j.arthro.2022.01.024] [Citation(s) in RCA: 14] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/15/2021] [Revised: 01/09/2022] [Accepted: 01/16/2022] [Indexed: 02/02/2023]
Abstract
PURPOSE To investigate whether hip arthroscopy (HA) is effective in patients with femoroacetabular impingement and concomitant hip osteoarthritis (OA) of Tönnis grade 2 or greater. METHODS This review was registered in the International Prospective Register for Systematic Reviews and Meta-analysis (PROSPERO, CRD42020210936). It followed the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) guidelines and included multiple databases: MEDLINE, Embase, Web of Science Core Collection, and Cochrane Library. All studies in English or German from database inception to December 1, 2020, that investigated outcomes of HA in patients with OA of Tönnis grade 2 or greater were considered eligible. The risk of bias was assessed using the MINORS (Methodological Index for Non-randomized Studies) tool. Data heterogeneity was explored using the I2 test in a random-effects model. RESULTS Eleven studies met the eligibility criteria. The MINORS (Methodological Index for Non-randomized Studies) score averaged 68% (range, 46%-81%). A total of 616 hips, consisting of 247 hips of interest (Tönnis grade 2 or greater) and 369 controls, were included. The weighted estimated follow-up averaged 29.1 months (range, 12-84 months). Data on patient-reported outcome measures (PROMs) could be extracted for 6 of 11 studies, and date on conversion to total hip arthroplasty were available for 8 of 11. Four studies reported an overall improvement in PROMs after HA, and 2 highlighted a failure of improvement in PROMs. Failure of HA with conversion to total hip arthroplasty was observed at a rate of 0% to 9% in 4 studies, as opposed to proportions as high as 35% to 70% in the other 4 studies. There was a high level of heterogeneity, with a calculated I2 value of 89%. CONCLUSIONS There is currently contradictory and insufficient evidence regarding the efficacy of HA for hips with femoroacetabular impingement and concomitant OA of Tönnis grade 2 or greater. This is in the context of data with low levels of evidence, mainly consisting of retrospective case series (Level IV) with a high risk of bias and high heterogeneity (I2 of approximately 90%). LEVEL OF EVIDENCE Level IV, systematic review of Level III and IV studies.

Does hip preservation surgery prevent arthroplasty? Quantifying the rate of conversion to arthroplasty following hip preservation surgery. J Hip Preserv Surg 2020; 7:168-182. [PMID: 33163202 PMCID: PMC7605779 DOI: 10.1093/jhps/hnaa022] [Citation(s) in RCA: 26] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/22/2019] [Revised: 03/12/2020] [Accepted: 04/18/2020] [Indexed: 12/15/2022] Open
Abstract
Hip arthroscopic surgery for femoroacetabular impingement and periacetabular osteotomy (PAO) for dysplasia is the most commonly used contemporary treatment for these conditions and has been shown to provide pain relief and restore function. What is less understood and perhaps of more interest to health economists, is the role of these procedures in preserving the hip joint and avoiding hip arthroplasty. The aim of this systematic review was to determine whether hip joint preservation surgery, indeed, preserves the hip joint by looking at conversion rates to total hip arthroplasty (THA). Two separate searches were undertaken, using PRISMA guidelines and utilizing PubMed and Open Athens search engines, identifying manuscripts that looked at conversion to THA following either hip arthroscopy (HA) or PAO. When considering HA, we found 64 eligible papers. Out of these studies, there were 59 430 hips with 5627 undergoing conversion to THA (9.47% [95% CI 9.23–9.71%]) with a mean conversion time of 24.42 months. Regarding PAO, there were 46 eligible papers including 4862 patients who underwent PAO with subsequent conversion to THA in 404 patients (8.31% [95% CI 7.54–9.12%]). with a mean conversion time of 70.11 months. Certain features were associated with increased conversion rates, including increasing age, worsening arthritis and joint space <2 mm. This study demonstrates that the mean conversion rates to be <10% for HA and PAO, during the mean follow-up periods of included manuscripts. Joint preserving surgery appears to defer or at least delay the need for THA.

Abstract
Objective To investigate the outcomes of hip arthroscopy for femoroacetabular impingement (FAI) in patients over the age of 50 years. Method This is a therapeutic case series study. A total of 27 FAI patients over the age of 50 years who met inclusion and exclusion criteria and were being followed up for at least 2 years in the orthopaedics department at our hospital between January 2015 and October 2017 were recruited for a prospective analysis on the outcomes of hip arthroscopy. All patients underwent unilateral surgery. Of the patients included, there were 15 men and 12 women, who were aged 50–74 years old (57 ± 6.4 years). The outcomes were assessed using the visual analog scale (VAS), the modified Harris hip score (mHHS), and the International Hip Outcome Tool (iHOT‐12). Results A total of 27 patients were followed up for at least 2 years. The postoperative center‐edge angle, the alpha angle, and the offset decreased significantly compared with preoperative measurements (P < 0.01). The mHHS before surgery and at 1 year and 2 years after surgery was 62.19 ± 7.47, 86.70 ± 5.80, and 87.89 ± 5.08, respectively; iHOT‐12 scores were 30.44 ± 4.22, 73.56 ± 3.89, and 73.77 ± 3.72, respectively; VAS scores were 6.07 ± 0.78, 1.93 ± 0.73, and 1.59 ± 0.64, respectively. As compared with the condition before surgery, there was a significant improvement in the mHHS, iHOT‐12, and VAS scores at 1 year and 2 years after surgery (P < 0.01). The mHHS score at 2‐year follow up after surgery was higher than that at 1 year after surgery, and the difference observed was statistically significant (P = 0.04). One patient with severe acetabular and femoral cartilage damage underwent total hip replacement 11 months after surgery. Conclusion Hip arthroscopy considerably improved hip symptoms and function in Chinese FAI patients aged 50 years or older who did not have severe radiographic osteoarthritis. The conversion to THA and complications were low. Strict surgical indications and appropriate surgical strategies lay the foundation for satisfactory postoperative results in elderly patients with FAI.

Functional Outcomes of Arthroscopic Treatment in Femoroacetabular Impingement in Patients over 60 Years Old Compared with Patients Aged 40 Years or Younger. Rev Bras Ortop 2020; 55:715-721. [PMID: 33364649 PMCID: PMC7748922 DOI: 10.1055/s-0040-1708515] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2018] [Accepted: 12/20/2019] [Indexed: 11/18/2022] Open
Abstract
Objective
To evaluate the functional outcomes of patients diagnosed with femoroacetabular impingement (FAI) older than 60 years, compared with those of patients of age 40 years or younger.
Methods
This was a retrospective review of patients with FAI who underwent hip arthroscopy between 2010 and 2015. The patients were adults aged over 60 years with Tönnis ≤ 1 matched in a 1:1 ratio with adults aged 40 years or younger, according to the type of deformity (cam, pincer, or mixed), sex, and the date when the surgery was performed.
Results
Thirty-four patients were included in each group. The mean age was 30.6 ± 6.9 years and 65.6 ± 4.6 years in the control and case groups, respectively. There were no significant differences between the groups at 1-year follow-up (
p
> 0.05). In the group with older patients (case group), we observed a change in the total Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score from 46.3 to 22.0 in the 1
st
postoperative year, while the control cases improved in the WOMAC score from 38.1 to 7.2 in relation to the preoperative stage.
Conclusion
In the group of patients ≤ 40 years old, a considerable change was observed in the WOMAC score without a statistical significance compared with the > 60 years group. This observation suggests that hip arthroscopy is beneficial when there is an appropriate selection of patients with FAI, regardless the age of the patient.

Abstract
BACKGROUND There has been a recent increase in the use of biologics in hip arthroscopy to assist in the management of femoroacetabular impingement (FAI). PURPOSE To analyze the current use of biologics for the treatment of FAI and its associated lesions. STUDY DESIGN Systematic review; Level of evidence, 4. METHODS A search of the PubMed, Medline, and EMBASE databases was performed in March 2019 with use of the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. The criterion for inclusion was observational, published research articles studying the therapeutic use of biologics as an adjuvant therapy during arthroscopic surgery for FAI; treatments included bone marrow aspirate concentrate, mesenchymal stem cells (MSCs), platelet-rich plasma (PRP), hyaluronic acid, growth factors, and autologous chondrocyte implantation (ACI) or autologous matrix-induced chondrogenesis (AMIC). RESULTS There were 9 studies that met the inclusion criteria, and a total of 674 patients were included across all studies. FAI was studied in all articles. Further, 7 studies (78%) also analyzed chondral injuries, and 3 studies also analyzed labral tears (33%). ACI or AMIC was used in 56% of studies and showed superior functional outcomes at short- and midterm follow-up versus debridement or microfracture. PRP did not improve the outcome of labral repairs at short-term follow-up. CONCLUSION The current literature regarding biologic adjuncts in hip arthroscopy is varied in quality, with only one level 1 study. The use of ACI/AMIC for medium-sized chondral lesions showed promising results in individual studies; however, these were of lower quality. To enable comparisons among future studies, investigators must ensure accuracy in the reporting of biologic preparations and formulations used and homogeneity in the type and severity of lesion treated.

PURPOSE The purposes of this review were (1) to collate and synthesize research studies reporting any outcome measure on both open and arthroscopic surgical treatment of femoroacetabular impingement (FAI) syndrome and (2) to report the prevalence and consistency of outcomes across the included studies. METHODS A computer-assisted literature search of the MEDLINE, CINAHL (Cumulative Index to Nursing and Allied Health Literature), and Embase databases was conducted using keywords related to FAI syndrome and both open and arthroscopic surgical outcomes, resulting in 2,614 studies, with 163 studies involving 14,824 subjects meeting the inclusion criteria. Two authors independently reviewed study inclusion and data extraction with independent verification. The prevalence of reported outcomes was calculated and verified by separate authors. RESULTS Between 2004 and 2016, there has been a 2,600% increase in the publication of surgical outcome studies. Patients had a mean duration of symptoms of 27.7 ± 21.5 months before surgery. Arthroscopy was the surgical treatment used in 71% of studies. The mean final follow-up period after surgery was 32.2 ± 17.3 months. Follow-up time frames were reported in 78% of studies. Ten different patient-reported outcome measures were reported. The alpha angle was reported to be measured 42% less frequently as a surgical outcome than as a surgical indication. Surgical complications were addressed in only 53% of studies and failures in 69%. Labral pathology (91% of studies reporting) and chondral pathology (61%) were the primary coexisting pathologies reported. Clinical signs, as defined by the Warwick Agreement on FAI syndrome, were reported in fewer than 25% of studies. CONCLUSIONS Most FAI syndrome patients have longstanding pain and potential coexisting pathology. Patient-reported outcome measures and diagnostic imaging are the most frequently reported outcomes. Measures of hip strength and range of motion are under-reported. It is unclear whether the inconsistency in reporting is because of lack of measurement or lack of reporting of specific outcomes in these studies. Current surgical outcomes are limited to mid-term surgical follow-up time frames and inconsistent outcome reporting. LEVEL OF EVIDENCE Level IV, systematic review of Level I through IV studies.

Osteoarthritis of the hip and knee in former male professional soccer players. Br Med Bull 2018; 125:121-130. [PMID: 29385409 DOI: 10.1093/bmb/ldy001] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/19/2017] [Accepted: 01/01/2018] [Indexed: 12/20/2022]
Abstract
BACKGROUND Professional soccer (PS) players are at great risk of osteoarthritis (OA) of the knee and hip. SOURCES OF DATA Following the PRISMA guidelines, the key words 'osteoarthritis' and 'soccer' or 'football' were matched with 'players' or 'former' or 'retired' and with 'hip' or 'knee' on December 24, 2017 in the following databases: PubMed, Cochrane, Google scholar, Embase and Ovid. Only comparative studies reporting the prevalence rate of OA of both hip and knee joint in former PS athletes (fPSa) and age and sex matched controls were considered. AREAS OF AGREEMENT In fPSa, the prevalence rate of OA of both hip and knee is significantly higher compared to age and sex matched controls. AREAS OF CONTROVERSY The pathological pathways responsible for the development of OA of the hip and knee in PS athletes (PSa) are still not clearly understood. GROWING POINTS The prevalence rate of clinical OA of the hip was 8.6% in fPSa and 5.6% in controls (odd ratio (OR) = 1.5; 95% CI: 1.06-2.31). The radiographic rate of OA was 21.2% in fPSa and 9.8% in controls (OR = 2.4; 95% CI: 1.66-3.69). A total of 14.6 and 53.7% of fPSa presented clinical and radiographic signs of OA of the knee, respectively, vs 12.9% (OR = 1.16; 95% CI: 0.86-1.55) and 31.9% (OR = 2.47; 95% CI: 2.03-3.00) of controls. Sonographic evidence of OA of the knee was found in 52% of fPSa and 33% of controls (OR = 2.2; 95% CI: 1.24-3.89). AREAS TIMELY FOR DEVELOPING RESEARCH Preventive training programmes should be developed to reduce the number of fPSa presenting early OA.
