Patient-Reported Outcomes in Athletes Following Hip Arthroscopy for Femoroacetabular Impingement with Sub-analysis on Return to Sport and Competition Level: A Systematic Review

Abstract One in four patients presenting with femoroacetabular impingement (FAI) has bilateral symptoms, and despite excellent outcomes reported after arthroscopic treatment of FAI, there remains a paucity of data on the outcomes following bilateral hip arthroscopy. This systematic review aims to examine the outcomes following bilateral (either ‘simultaneous’ or ‘staged’) versus unilateral hip arthroscopy for FAI. A systematic review of multiple electronic databases was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and checklist. All studies comparing simultaneous, staged and/or unilateral hip arthroscopy for FAI were eligible for inclusion. Case series, case reports and reviews were excluded. All study, patient and hip-specific data were extracted and analyzed. The Newcastle–Ottawa Scale was used to assess study quality. A meta-analysis was not performed due to heterogeneity among outcome measures. A total of six studies, including 722 patients (42.8% male) and 933 hips were eligible for inclusion. The mean age across patients was 35.5. The average time between staged procedures was 7.7 months. Four of the six studies were retrospective cohort studies, while the remaining two were prospective in nature. The overall quality of the eligible studies was found to be good. No significant difference was noted among patient-reported outcomes (modified Harris hip score, hip outcome score and non-arthritic hip score), visual analog scale, return to sport, traction time and complications between those undergoing bilateral (simultaneous or staged) versus unilateral hip arthroscopy. Based on the current available evidence, bilateral hip arthroscopy (whether simultaneous or staged) exhibits similar efficacy and safety when compared with unilateral hip arthroscopy. However, further prospective study is required to confirm this finding.

Background: Femoroacetabular impingement (FAI) has become a more commonly recognized cause of limited hip range of motion and hip pain among young adults and athletes. Hip arthroscopy is recommended for the surgical treatment of this disorder, unless specific contraindications exist. Despite the increasing rate of published studies in this area, there remains no aggregate data for outcomes after this approach. Purpose: To evaluate risk factors and outcomes after arthroscopic management of FAI, including return to play, revision rate, surgical and nonsurgical complications, change in α-angle, intraoperative bone resection, and patient-reported outcomes. Study Design: Meta-analysis and systematic review. Methods: A review of the current literature was performed with the terms “femoroacetabular impingement,” “hip arthroscopy,” and numerous variations thereof in PubMed, EMBASE, BioMed Central, Cochrane, Science Direct, and Scopus, yielding 1723 abstracts. After screening by eligibility criteria, 31 articles were included. The incidence of bilateral FAI was determined by enrollment data, and pooled estimates were calculated for postoperative patient-reported outcome measures, α-angles, return to sport, postoperative complications, and reoperation risk. Results: A total of 1981 hips among 1911 patients were identified, with a mean ± SD age of 29.9 ± 1.9 years and 29.5 ± 14.0 months of follow-up. The incidence of bilateral FAI in these studies that required operative intervention was 3.6%. The pooled risk of reoperation after hip arthroscopy, including revision surgery or subsequent total hip arthroplasty, was 5.5% (95% CI, 3.6%-7.5%). The risk of clinical complications was 1.7% (95% CI, 0.9%-2.5%). In total, 87.7% of patients demonstrated return to sport after surgery (95% CI, 82.4%-92.9%, P < .001), and all patient-reported outcomes improved postoperatively, with the highest increase observed in the Hip Outcome Score sports scale (41.7 points; 95% CI, 34.1-49.4; P < .001). The α-angle decreased by an average of 23.6° (95% CI, 18.2°-29.0°; P < .001). We identified 11 factors associated with the success of hip arthroscopy in FAI and 16 factors associated with failure or negative outcomes. Conclusion: A high percentage of patients return to sport activities after hip arthroscopy for FAI, with a low rate of complications and reoperation. All patient-reported outcome measures, except for mental health, significantly improved after surgery.

Rehabilitation Protocols

Abstract The purpose of this study was to analyze the effect of structured physical therapy protocols on patient-reported outcomes (PROs) following hip arthroscopy. A literature search was completed in October 2019 according to Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines to identify articles reporting specific rehabilitation protocols following hip arthroscopy that document PROs. Studies meeting all inclusion and exclusion were reviewed and data were extracted. Six studies were included in analysis. The mean age was 34.7% and 56.6% were males. Five studies described rehabilitation protocols in phases with specific goals and progression criteria. All studies included range of motion (ROM) and weight-bearing (WB) precautions. Return to sport (RTS)/activity varied between 7 and 32 weeks. The studies used variations of 21 different PROs. Significant improvements in baseline and post-operative PROs noted across studies. Rehabilitation protocols following hip arthroscopy typically consist of 4–5 phase programs with set goals and progression criteria. Several commonalities existed between studies on WB, ROM precautions and gait normalization. However, timing and recommendations for RTS/return to work varied between studies and were dependent on the concomitant procedures performed as well as type of patient population. Clinically significant improvement in PROs from baseline noted in majority of the studies reviewed that involved a structured rehabilitation program following arthroscopic management of femoroacetabular impingement. As there is heterogeneity in patient-specific characteristics across the included studies, no determination can be made as to which protocol is most effective and further high-quality comparative studies are needed. Clinical relevance: Adopting phase-based rehabilitation protocols following arthroscopic femoroacetabular impingement treatment help achieve improved outcomes that are predictable

Acetabular Overcoverage

Background: Patients with pincer-type femoroacetabular impingement are commonly treated with arthroscopic reduction of acetabular depth as measured by the lateral center-edge angle (LCEA). The optimal amount of rim reduction has not been established, although large resections may increase contact pressures through the hip. A recent publication demonstrated inferior surgical outcomes in patients with acetabular overcoverage as compared with normal acetabular coverage. Casual observation of our database suggested equivalent improvements, prompting a similar analysis. Purpose: To analyze patient-reported outcomes after hip arthroscopy for femoroacetabular impingement in patients with acetabular overcoverage who were matched with controls with normal coverage, as well as to analyze associations with reduction in LCEA. Study Design: Cohort study; Level of evidence, 3. Methods: Data were collected prospectively from patients with a minimum 2-year follow-up after receiving hip arthroscopy for femoroacetabular impingement by a single surgeon. Cases were reviewed to identify those with pincer-type morphology (LCEA >40°) and matched according to sex, age, chondral damage, and surgery date in a 1:1 ratio with controls with an LCEA of 25° to 40°. The surgical goal was to reduce the LCEA to the upper end of the normal range with minimal rim resection, usually 35° to 37°. Radiographic measurements of coverage, intraoperative findings, procedures, and patient-reported outcomes were recorded, including the 12-Item International Hip Outcome Tool, Non-arthritic Hip Score, Hip Disability and Osteoarthritis Outcome Score, visual analog scale for pain, rates of revision or reoperation, and conversion to total hip arthroplasty. Results: A total of 114 hips (93 patients) for the pincer group were matched 1:1 from 616 hips (541 patients) for the control group. The pincer group (mean ± SD age, 34.5 ± 12.2 years) did not differ in age, body mass index, or follow-up from controls. LCEA was reduced in both groups pre- to postoperatively: the pincer group from 44.0° ± 2.8° to 34.2° ± 3.5° and the controls from 32.9° ± 3.9° to 31.0° ± 3.0°. No differences in improvement were observed: iHOT-12 improved by 35.7 points in both groups ( P = .9 for analysis of variance interaction) and Nonarthritic Hip Score by 22.3 points ( P = .6). From all eligible surgical procedures, 2-year follow up rates were 2.5% and 2.6% for the pincer and control cohorts, respectively, and 1.2% and 0.3% for conversion to total hip arthroplasty. Conclusion: Arthroscopic management of acetabular overcoverage can achieve excellent results, equivalent to arthroscopy for other causes of symptomatic femoroacetabular impingement. A key finding was smaller rim resections producing a mean postoperative LCEA of 34.2° with a small standard deviation.

Modified Harris Hip Score

Objectives: To determine the rate of return to sport (RTS) in high-level athletes undergoing bilateral hip arthroscopy and report minimum 1-year patient-reported outcomes (PROs) for this cohort. We hypothesized that RTS rates, as well as sport-specific PROs, will be lower than the rates and scores previously reported in the literature for unilateral hip arthroscopy. Methods: Data were prospectively collected on all patients undergoing hip arthroscopy at our institution from November 2011 to July 2018. Patients were included if they underwent bilateral hip arthroscopy and were either a high school, collegiate, or professional athlete prior to their first surgery. RTS was defined as a patient’s return to competitive participation in their respective sport. Additional PROs, including modified Harris Hip Score (mHHS), nonarthritic hip score (NAHS), and Hip Outcome Score-Sports Specific Subscale (HOS-SSS), as well as complication rates and future surgeries were documented and compared for all patients. Results: A total of 87 patients met inclusion criteria, for which follow-up was available for 82 (94.3%). At latest follow-up, 44 (53.7%) patients returned to sport. Of patients returning, 56% did so at the same level or higher. The most common reasons for not returning to sport were due to graduation/lifestyle change (47.4%) and hip symptoms (44.7%). Patients returning to sport had significantly higher PROs at latest follow-up relative to those who did not return, including for mHHS (93.7 vs. 87.5), NAHS (94.4 vs. 88.2), HOS-SSS (90.9 vs. 78.2) (P < 0.05). Rates of achieving PASS and MCID for mHHS were not significantly different. However, for HOS-SSS, patients who returned had significantly higher rates of achieving the MCID and PASS. Conclusion: Rates of RTS after bilateral hip arthroscopy are lower than those after unilateral hip arthroscopy. When comparing patients that returned to sports and those who did not return, we show that although both groups show a significant improvement in PROs following surgery, those that returned to sport achieved significantly higher scores in all outcome measures. In addition, patients returning to sports showed a significantly higher rate of attaining MCID and PASS scores for the HOS-SSS, possibly attesting to the validity of this score and its thresholds.

Background: Threshold values for patient-reported outcome measures, such as the minimum clinically important difference (MCID) and patient acceptable symptomatic state (PASS), are important for relating postoperative outcomes to meaningful functional improvement. Purpose: To determine the PASS and MCID after hip arthroscopy for femoroacetabular impingement using the Patient-Reported Outcomes Measurement Information System (PROMIS) questionnaire. Study Design: Cohort study (diagnosis); Level of evidence, 3. Methods: A consecutive series of patients undergoing primary hip arthroscopy for femoroacetabular impingement were administered preoperative and minimum 1-year postoperative PROMIS surveys focusing on physical function (PF) and pain interference (PI). External anchor questions for the MCID and PASS were given with the postoperative PROMIS survey. Receiver operator curves were constructed to determine the threshold values for the MCID and PASS. Curves were generated for the study population as well as separate cohorts segregated by median baseline PF or PI scores and preoperative athletic participation. A multivariate post hoc analysis was then constructed to evaluate factors associated with achieving the PASS or MCID. Results: There were 113 patients (35% male; mean ± SD age, 32.8 ± 12.5 years; body mass index, 25.8 ± 4.8 kg/m2), with 60 (53%) reporting preoperative athletic participation. Survey time averaged 77.5 ± 49.2 seconds. Anchor-based MCID values were 5.1 and 10.9 for the PF and PI domains, respectively. PASS thresholds were 51.8 and 51.9 for the PF and PI, respectively. PASS values were not affected by baseline scores, but athletic patients had a higher PASS threshold than did those not participating in a sport (53.1 vs 44.7). MCID values were affected by preoperative baseline scores but were largely independent of sports participation. A post hoc analysis found that 94 (83%) patients attained the MCID PF while 66 (58%) attained the PASS PF. A multivariate nominal logistic regression found that younger patients ( P = .01) and athletic patients ( P = .003) were more likely to attain the PASS. Conclusion: The PROMIS survey is an efficient metric to evaluate preoperative disability and postoperative function after primary hip arthroscopy for femoroacetabular impingement. The MCID and PASS provide surgeons with threshold values to help determine PROMIS scores that are clinically meaningful to patients, and they can assist with therapeutic decision making as well as expectation setting.

Background: In patients with femoroacetabular impingement, preoperative diagnostic injections are commonly used to establish a diagnosis of intra-articular pathology. In some cases, intra-articular steroid injections are also used for therapeutic purposes. Purpose/Hypothesis: The purpose of this study was to determine if a positive response to intra-articular steroid injection was predictive of superior outcomes after hip arthroscopy to determine if the response to intra-articular steroid injection was predictive of outcomes after hip arthroscopy. It was hypothesized that a positive response to a preoperative hip injection would be predictive of improved short- to midterm outcomes after hip arthroscopy. Study Design: Cohort study; Level of evidence, 3. Methods: This was a retrospective study of 208 patients who elected to have ultrasound-guided intra-articular steroid injection before they underwent hip arthroscopy between January 2016 and December 2016. Patients were divided into 2 groups: those who showed improvement in pain after the injection (steroid responder group) and those who showed no response (nonresponder group). The authors compared the preoperative and 2-year postoperative patient-reported outcomes (modified Harris Hip Score [mHHS] and Hip Outcome Score–Activities of Daily Living [HOS-ADL]) and radiographic findings between groups. Clinical endpoints, including rates of revision and conversion to total hip arthroplasty, were also reviewed. Results: There were 88 patients in the nonresponder group and 120 patients in the responder group, with no significant between-group differences in preoperative descriptive variables. The responder group had significantly higher 2-year mHHS and HOS-ADL, pre- to postoperative change in mHHS and HOS-ADL, percentage of patients achieving the patient acceptable symptomatic state (PASS) on the mHHS, and percentage of patients reaching the minimum clinically important difference and the PASS on the HOS-ADL. There was no difference in Tönnis grade, acetabular labrum articular disruption grade, revision rate, or conversion to total hip arthroplasty between the 2 groups. Conclusion: The response to preoperative intra-articular injection did aid in predicting 2-year patient-reported outcomes of hip arthroscopy for femoroacetabular impingement. Overall, the result of a preoperative intra-articular injection can be a helpful clinical tool for surgical decision-making and counseling patients on expected outcomes after hip arthroscopy.

Background: Previous studies have demonstrated hip arthroscopy to be an effective treatment for femoroacetabular impingement (FAI) in individuals 18 years of age and older. Long-term outcome data in the adolescent population, however, are limited. Purpose: To report 10-year outcomes after hip arthroscopy in adolescents with symptomatic FAI. Study Design: Case series; Level of evidence, 4. Methods: Prospectively collected data were analyzed on adolescent patients younger than 18 years of age who had hip arthroscopy between March 2005 and 2009 with a minimum 10-year follow-up. Patients were included if they were diagnosed with symptomatic FAI and an associated labral tear that was treated with repair. Patients were excluded if they had previous hip procedures, acetabular dysplasia (lateral center-edge angle, <20°), avascular necrosis, previous hip fracture or dislocation, or Legg-Calve-Perthes disease, or refused to participate. The primary patient-reported outcome measure was the Hip Outcome Score (HOS) Activities of Daily Living (ADL) subscale. In addition, the HOS—Sport, modified Harris Hip Score (mHHS), 12-Item Short Form Health Survey (SF-12), and patient satisfaction were collected. Failure was defined as patients having to undergo revision arthroscopy. Results: There were 60 patients (70 hips) who met inclusion criteria and had a 10-year follow-up. The mean age of the cohort was 16 ± 1.2 years, with 21 male and 49 female hips. Seven hips (10%) required revision hip arthroscopy. All revisions occurred in female patients and were associated with global laxity as well as longer duration of symptoms before time of surgery. At a mean follow-up of 12 years (range, 10-14 years), patients who did not undergo revision surgery had significant improvements from preoperatively to postoperatively in HOS-ADL (from 64 to 92; P < .01), HOS–Sport (from 40 to 86; P < .01), mHHS (from 56 to 88; P < .01), and SF-12 Physical Component Summary (from 41 to 54; P < .01). The median patient satisfaction was 10 out of 10 (very satisfied). Conclusion: Hip arthroscopy for FAI with labral repair resulted in excellent patient-reported outcomes and satisfaction at a minimum of 10 years of follow-up. There was a 10% rate of revision surgery, which was associated with global laxity and longer duration of symptoms before surgery, which should be considered in patient selection.

Background: No previous systematic review has focused on the athletes who fail to return to sport after hip arthroscopy for femoroacetabular impingement syndrome (FAIS). Purpose: To review the literature on the athletes who fail to return to sport after hip arthroscopy for FAIS to determine the rate of nonreturning athletes and explore the reasons for their inability to return to sport after arthroscopic FAI surgery. Study Design: Systematic review and meta-analysis. Methods: Three electronic databases were searched for eligible articles. Two reviewers independently screened the titles, abstracts, and full-text articles using prespecified criteria. Eligible articles were those that clearly stated the rate of athletes who did not return to sport after hip arthroscopy for FAIS. Data collected were the rate of patients who did not return to sport, the level of competition (high level, recreational, or mixed), the type of sport, comments on patients who did not return to sport, the rate of subsequent hip surgeries (total hip replacement or revision hip arthroscopy) in nonreturning athletes, and the reported reason for not returning to sport. A random-effects model was used for meta-analysis. Results: Twenty studies were eligible for inclusion, and 1093 athletes were analyzed. The weighted rate of athletes who did not return to sport after hip arthroscopy for FAIS was 12.1% (95% CI, 7.7-17.4). Only 2 studies (2/20;10%) reported the age of the athletes who did not return, while sex was reported in 3 studies (3/20;15%). The estimated proportion of athletes who did not return to sport because of hip-related issues was significantly greater than the percentage of athletes who did not return for reasons unrelated to their hip (74.3% vs 22.3%; P < .0001). Persistent hip pain was the most commonly reported factor (52/110 patients; 47.2%) associated with failure to return to sport. Whether the nonreturning athletes underwent any subsequent hip procedure after hip arthroscopy for FAIS was reported in only 4 out of 20 studies (20%). There was evidence of publication bias and study heterogeneity. Conclusion: The estimated rate of athletes who did not return to sport after hip arthroscopy for FAIS was 12%, with the majority of athletes being unable to return because of persistent hip pain. There is a severe lack of evidence on the athlete characteristics and clinical course of the nonreturning athletes, and the rate of subsequent hip procedures is unknown. The outcomes and reasons for athletes not returning to sport should be reported in detail to improve patient care.

Modified Harris Hip Score

Background: Although the negative effects of smoking have been documented for other types of arthroscopic procedures, there is limited information regarding its influence on hip arthroscopy outcomes. Purpose: To examine the effect of smoking on the following outcomes after hip arthroscopy: patient-reported outcomes (PROs), the degree of improvement in PROs relative to baseline, complication rates, and rates of revision arthroscopy and/or conversion to total hip arthroplasty (THA). Study Design: Systematic review. Methods: The PubMed, Embase, and Cochrane Library databases were queried for studies published between January 1, 1985, and January 14, 2020, comparing the outcomes of hip arthroscopy between smokers and nonsmokers. Case reports, basic science studies, and studies investigating pediatric patients or lacking a description of outcomes were excluded. Included outcome tools were the modified Harris Hip Score, the visual analog scale (VAS) for pain and satisfaction, and the Hip Outcome Score (HOS)–Sports Specific and HOS–Activities of Daily Living. Preoperative characteristics and operative indications were also recorded. Results: Postoperative combined means (± SD) were better in nonsmokers versus smokers for the modified Harris Hip Score (75.67 ± 20.88 vs 82.32 ± 15.5; P = .001), the VAS pain (3.13 ± 2.79 vs 2.13 ± 2.21; P < .001), and the HOS–Sports Specific (62.54 ± 25.38 vs 71.7 ± 23.3; P < .001). There was no difference between groups in VAS satisfaction ( P = .23) or HOS–Activities of Daily Living ( P = .13). The extent of PRO score improvement relative to baseline values was similar in smokers and nonsmokers in all PRO measures ( P > .05 for all). Smokers demonstrated higher rates of postoperative thromboembolic ( P = .0177) and infectious ( P = .006) complications. There was no difference between rates of revision arthroscopy ( P = .47) and THA conversion ( P = .31). Conclusion: Smoking adversely affects certain postoperative PROs and is associated with higher postoperative complication rates. Further studies are required investigating the degree of PRO improvement and long-term arthroscopy revision and THA conversion rates.
