Background: The use of hip arthroscopic surgery in the treatment of femoroacetabular impingement (FAI) is increasing, but it is universally known as a technically demanding procedure with a “steep” learning curve. There are limited data investigating the correlation between surgeon experience and patient-reported outcomes (PROs) as well as procedure and traction times. Purpose: To prospectively evaluate the relationship between surgeon experience and PROs after hip arthroscopic surgery for the treatment of FAI. Study Design: Cohort study; Level of evidence, 2. Methods: A total of 190 patients undergoing primary hip arthroscopic surgery for FAI were prospectively enrolled during a sports medicine fellowship–trained surgeon’s first 36 months of practice. A radiographic evaluation as well as PRO surveys including the 12-Item Short Form Health Survey (SF-12), the modified Harris Hip Score (mHHS), and the Hip disability and Osteoarthritis Outcome Score (HOOS) were administered preoperatively and at 2 years postoperatively. Logistic regression as well as analysis of variance was performed to evaluate for correlations between surgical experience and PROs, procedure time, and traction time. Results: Of the 190 patients, 168 (88%; mean age, 35.3 ± 9.6 years; mean body mass index, 25.07 ± 3.98) completed a 2-year follow-up and were included for analysis. The mean procedure time was 91.5 ± 23.9 minutes, and the mean traction time was 54.0 ± 17.7 minutes. Patients demonstrated significant improvements at 2 years after surgery for all PRO scores (mHHS, HOOS, and SF-12 physical component summary; P < .001), except the SF-12 mental component summary, which had no change ( P = .43). The procedure time significantly decreased after 70 cases, while the traction time continued to decrease until 110 cases ( R 2 = 0.99; P < .0001). There was no correlation between increasing case volume and 2-year PRO scores ( P > .2 for mHHS, HOOS, and SF-12). There was also no difference with increasing case volume and amount of improvement from preoperative to 2-year postoperative PRO scores for the SF-12 and HOOS. Case volume did not affect the complication rate, as this cohort experienced 4 minor cases of neurapraxia. Conclusion: Surgical efficiency in hip arthroscopic surgery for the treatment of FAI was maximized after 110 cases in this cohort. However, significant PRO improvements can be achieved early in a surgeon’s practice prior to maximizing surgical efficiency.

Background: There is a plethora of literature on outcomes after hip arthroscopic surgery in the adult population; however, outcomes in the adolescent population have not been as widely reported. Additionally, as adolescents represent a very active population, it is imperative to understand their athletic activity and return to sport after hip arthroscopic surgery. Purpose: To analyze patient-reported outcomes (PROs) after hip arthroscopic surgery in adolescents (aged 10-19 years) and present a return-to-sport analysis in the athletic adolescent subgroup. Study Design: Systematic review; Level of evidence, 4. Methods: The PubMed, Embase, and Cochrane databases were searched according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines to identify articles that reported PROs after hip arthroscopic surgery in adolescents. The standardized mean difference was calculated to compare the effect size of hip arthroscopic surgery on various PROs. For the athletic subgroup, a return-to-sport summary was also provided. Results: Ten studies, with 618 adolescent hips and a collective study period of December 2004 to February 2015, were included in this systematic review. Across all studies, the mean age was 15.8 years (range, 11.0-19.9 years), and female patients composed approximately 56.7% of the entire cohort. The mean follow-up was 34.5 months (range, 12-120 months). The modified Harris Hip Score (mHHS) was reported in 9 studies, and at latest follow-up, scores were excellent in 4 studies (range, 90-95) and good in the remaining 5 studies (range, 82.1-89.6). All adolescents also showed significant improvement on the Non-Arthritic Hip Score (NAHS), the Hip Outcome Score–Activities of Daily Living (HOS-ADL), the HOS–Sport-Specific Subscale (HOS-SSS), the physical component of the 12-Item Short Form Health Survey (SF-12P), a visual analog scale for pain (VAS), and both versions of the International Hip Outcome Tool (iHOT-12 and iHOT-33) at latest follow-up ( P < .05). Further, mean improvements reported in all studies surpassed reported values of the minimal clinically important difference and patient acceptable symptomatic state for the mHHS, HOS-ADL, HOS-SSS, and iHOT-33. Finally, the collective return-to-sport rate among athletic adolescents was 84.9%. Conclusion: In the setting of labral tears and femoroacetabular impingement, hip arthroscopic surgery can safely be performed in adolescents and leads to significant functional improvement. Furthermore, athletic adolescents return to sport at high levels after hip arthroscopic surgery.

Background: Hip arthroscopic surgery is a rapidly growing procedure, but it may be associated with a steep learning curve. Few studies have used patient-reported outcome (PRO) surveys to investigate the relationship between surgeon experience and patient outcomes after the arthroscopic treatment of femoroacetabular impingement (FAI). Hypothesis: Patients undergoing hip arthroscopic surgery for the treatment of FAI in the early stages of a surgeon’s career will have significantly worse outcomes and longer procedure times compared with patients treated after the surgeon has gained experience. Study Design: Cohort study; Level of evidence, 2. Methods: Patients undergoing hip arthroscopic surgery for FAI and labral injuries were prospectively enrolled during a sports medicine fellowship–trained surgeon’s first 15 months of practice. Patients were stratified into an early group, consisting of the first 30 consecutive cases performed by the surgeon, and a late group, consisting of the second 30 consecutive cases. Radiographic and physical examinations were performed preoperatively and postoperatively. PRO surveys, including the 12-item Short Form Health Survey (SF-12), the modified Harris Hip Score (mHHS), and the Hip disability and Osteoarthritis Outcome Score (HOOS), were administered preoperatively and at a minimum of 1 year postoperatively. Results: There was no difference between the early and late groups for patient age (37.2 ± 11.5 vs 35.3 ± 10.8 years, respectively; P = .489), body mass index (25.6 ± 4.0 vs 25.1 ± 4.5 kg/m2, respectively; P = .615), or sex ( P = .465). There was a significantly increased procedure time (119.3 ± 21.0 vs 99.0 ± 28.6 minutes, respectively; P = .002) and traction time (72.7 ± 21.4 vs 59.0 ± 16.7 minutes, respectively; P = .007) in the early group compared with the late group. Mean postoperative PRO scores significantly improved in both groups compared with preoperative values for all surveys except for the SF-12 mental component summary. No differences were found in PRO score improvements or complication rates between the early and late groups. Conclusion: The total procedure time and traction time decrease after a surgeon’s first 30 hip arthroscopic surgery cases for FAI and labral tears, but patient outcomes can similarly improve regardless of surgeon experience in the early part of his or her career.

Background: Hip arthroscopic surgery in patients with borderline dysplasia continues to be controversial. In addition, it has been suggested that ligamentum teres (LT) tears may lead to inferior short-term patient-reported outcomes (PROs) when compared with a match-controlled group. Purposes: (1) To report minimum 5-year PROs in patients with borderline dysplasia and LT tears who underwent hip arthroscopic surgery and (2) to compare these PROs to those of a matched-pair control group of patients with borderline dysplastic hips without LT tears. Study Design: Cohort study; Level of evidence, 3. Methods: Data were prospectively collected for patients who underwent hip arthroscopic surgery between September 2008 and August 2013. Patients were included if they had a preoperative diagnosis of borderline dysplasia (lateral center-edge angle [LCEA], 18°-25°) and had preoperative and minimum 5-year postoperative modified Harris Hip Score (mHHS), Nonarthritic Hip Score (NAHS), and visual analog scale (VAS) for pain scores. Exclusion criteria were osteoarthritis of Tönnis grade >1, previous hip conditions, any previous ipsilateral hip surgery, or workers’ compensation status. There were 2 borderline dysplastic groups created. An LT tear group was matched 1:1 to a control group (no LT tear) with similar age, sex, body mass index (BMI), and laterality via propensity score matching. Significance was set at P < .05. Results: A total of 24 patients with an LT tear (24 hips) were matched to 24 patients without an LT tear (24 hips). There was no significant difference in age, sex, BMI, or laterality between groups. The mean age was 36.2 ± 17.2 and 34.9 ± 15.9 years for the control and LT tear groups, respectively ( P = .783). There were 17 (70.8%) and 16 (66.7%) female patients in the control and LT tear groups, respectively, and the mean preoperative LCEA was 23.3° and 22.2° in the control and LT tear groups, respectively. No differences were observed between groups in baseline PROs, intraoperative findings, or surgical procedures. LT debridement was performed in 17 (70.8%) patients in the LT tear group compared with 0 (0.0%) in the control group. Also, 5-year postoperative PROs were comparable in both groups, with the control group exhibiting superior Veterans RAND 12-Item Health Survey (VR-12) mental ( P = .041) and Short Form–12 (SF-12) mental ( P = .042) scores. Finally, hips with an intact LT were significantly more likely ( P = .022) to achieve the patient acceptable symptomatic state (PASS) for the mHHS (100.0% and 75.0%, respectively). No significant differences were present between the groups for the minimal clinically important difference (MCID) of the mHHS ( P = .140), MCID of the Hip Outcome Score–Sport-Specific Subscale (HOS-SSS) ( P = .550), or PASS of the HOS-SSS ( P = .390). Conclusion: After hip arthroscopic surgery, patients with borderline dysplasia and LT tears demonstrated favorable PROs at a minimum 5-year follow-up. Outcomes were similar to a matched-pair control group without LT tears, with the group with intact LTs showing higher VR-12 mental and SF-12 mental scores. Furthermore, patients with borderline dysplasia and intact LTs were significantly more likely to achieve the PASS for the mHHS.

Background: It remains controversial whether hip arthroscopic surgery should be applied to patients with a borderline developmental dysplastic hip (BDDH). Purpose: To review the outcomes of hip arthroscopic surgery for a BDDH and which factors influence these outcomes. Study Design: Systematic review. Methods: PubMed, Embase, and the Cochrane Library were searched through March 2018 for studies reporting the outcomes of primary hip arthroscopic surgery in patients with a BDDH. Inclusion in the review was based on the definition of a BDDH, patient-reported outcomes, and duration of follow-up. The primary outcome was the modified Harris Hip Score (mHHS). The failure rate, visual analog scale, satisfaction score, and patient-reported outcomes such as the Hip disability and Osteoarthritis Outcome Score were defined as secondary outcomes. Results: Nine studies with 425 patients who underwent hip arthroscopic surgery were included in this review. The mean follow-up times ranged from 25.4 to 28.8 months across the studies. A significant improvement was obtained in the mHHS, with a mean score of 61.8 preoperatively to 82.8 postoperatively; all other patient-reported outcomes also improved significantly, except the 12-Item Short Form Health Survey mental component summary. The overall failure rate was 14.1%, and the mean reoperation rate was 8.5%. The rate of conversion to total hip arthroplasty ranged from 4.4% to 26.0%, and the rate of conversion to periacetabular osteotomy was 4.0%. Combined defects such as cartilage damage, hip osteoarthritis, ligamentum teres tears, and femoroacetabular impingement could influence the outcomes after arthroscopic surgery in BDDHs. Conclusion: Hip arthroscopic surgery was demonstrated to be a promising approach for BDDHs, but the outcomes could be influenced by multiple risk factors. A higher level of evidence is still needed to support current findings.

Objectives: Although patients have been found to have significant improvements after hip arthroscopy for femoroacetabular impingement (FAI), prior studies suggest women have worse outcomes compared to men. These previous studies lack comparisons of patient reported outcome (PRO) scores based on gender with respect to clinical significance measurements, including the minimal clinically important difference (MCID) and patient acceptable symptom state (PASS). Therefore, the purpose of this study is to evaluate outcomes following hip arthroscopy for FAI based on patient gender by prospectively assessing changes in PRO scores, MCID, and PASS. Methods: Women and men undergoing hip arthroscopy for FAI were prospectively enrolled and preoperative radiographic and intra-operative findings were collected. The cohort was stratified based on self-identified patient gender so the term gender as well as the terms women and men were used to describe the patients as opposed to sex and the terms female and male. Patients completed the following PRO surveys before surgery and 2-years postoperatively: modified Harris Hip Score (mHHS), Hip disability and Osteoarthritis Outcome Score (HOOS), and the 12-Item Short Form Health survey (SF-12). Mean scores and the percentage of patients reaching MCID and PASS were analyzed. An a priori power calculation was performed which determined 42 hips in each group were needed to adequately power the study to 95%. Results: A total of 131 hips, from 72 women and 59 men were included. The mean ± SD age for women and men was 34.2 ± 9.5 vs 35.8 ± 10.3 years, respectively; P= .347 and body mass index (BMI) of 24.9 ± 4.4 vs 25.5 ± 3.3 kg/m2, respectively; P= .379. Women had smaller preoperative alpha angles (59.1 vs 63.7, respectively; P< 0.001) and lower acetabular cartilage injury grade (6.9% vs 22.0% with grade 4 injury, respectively; P= 0.013). Both women and men achieved equivalent significant improvements in PRO scores after surgery (PRO scores increased 18.4 to 45.1 points for mHHS and HOOS). Women and men reached PASS for mHHS at similar rates (76.4% and 77.2%, respectively; P=0.915). MCID was also achieved at similar rates between women and men for all scores (ranged 61.4% to 88.9%) except HOOS-ADL in which a higher percentage of women reached MCID compared to men (79.2% vs 62.7%, respectively; P= .037). Additional stratification by age group using the median cohort age of 34 showed no significant differences in PRO improvement based on age group for each gender. Conclusions: Women can achieve clinically meaningful improvements in patient reported outcomes scores after hip arthroscopy for FAI. Compared to men, women demonstrated equivalent high rates of achieving MCID and PASS at 2 years following surgery. [Table: see text]

Background: Labral tears are the most common abnormalities in patients undergoing hip arthroscopic surgery. Appropriate management is crucial, as it has been shown that better overall outcomes can be achieved with labral restoration. Purpose: To report the patient-reported outcomes (PROs) at minimum 2-year follow-up of patients who underwent hip arthroscopic surgery for labral tear repair using the knotless controlled-tension anatomic technique in the setting of femoroacetabular impingement syndrome (FAIS). Study Design: Case series; Level of evidence, 4. Methods: Data were prospectively collected for patients who underwent hip arthroscopic surgery for FAIS for labral tear repair using the knotless controlled-tension anatomic technique. Patients were excluded if they had prior hip conditions, prior ipsilateral surgery, Tönnis grade >1, a lateral center-edge angle (LCEA) <25°, or workers’ compensation claims. Preoperative and postoperative scores at minimum 2-year follow-up were recorded for the modified Harris Hip Score (mHHS), Nonarthritic Hip Score (NAHS), Hip Outcome Score–Sport-Specific Subscale (HOS-SSS), International Hip Outcome Tool (iHOT-12), and visual analog scale (VAS) for pain. The proportion of patients who achieved the minimal clinically important difference (MCID) or patient acceptable symptomatic state (PASS) for the mHHS, HOS-SSS, and iHOT-12 were also reported. Results: A total of 309 hips were included. The mean patient age was 36.2 years (range, 12.8-75.9 years). The mean preoperative LCEA and alpha angle were 31.9° and 57.1°, respectively. A significant improvement on the mHHS (62.6 ± 15.7 preoperatively vs 86.9 ± 16.2 at 2-year follow-up), NAHS (63.1 ± 16.7 vs 86.1 ± 16.7), and HOS-SSS (39.8 ± 22.0 vs 74.2 ± 27.3) was found ( P < .001 for all). A significant decrease was shown for VAS scores ( P < .001). Also, 78.6% and 82.2% of patients achieved the MCID and PASS for the mHHS, respectively; 60.8% and 69.9% of patients met the MCID and PASS for the HOS-SSS, respectively; and the MCID for the iHOT-12 was met by 77.3% of patients. Conclusion: In the setting of FAIS and labral tears, patients who underwent hip arthroscopic surgery for labral tear repair using the knotless controlled-tension anatomic technique demonstrated significant improvement in several validated PRO measures, the VAS pain score, and patient satisfaction at a minimum 2 years of follow-up. Based on this evidence, labral tear repair using the knotless controlled-tension anatomic technique seems to be a safe option.

Background: The literature contains conflicting reports regarding whether outcomes of hip arthroscopic surgery for patients with borderline dysplasia are inferior to outcomes in patients with normal acetabular coverage. Purpose: To assess differences in the outcomes of hip arthroscopic surgery for femoroacetabular impingement (FAI) in groups of patients with borderline dysplasia and normal coverage. Study Design: Cohort study; Level of evidence, 3. Methods: A registry of consecutive patients who had undergone primary hip arthroscopic surgery with capsular plication for FAI between January 2012 and January 2014 were divided based on the preoperative lateral center-edge angle (LCEA) into 2 distinct groups: (1) borderline dysplasia (LCEA 18°-25°) and (2) normal acetabular coverage (LCEA 25.1°-40°). There were 36 patients in the borderline dysplastic group and 312 patients in the normal coverage group. The primary outcome measure was the Hip Outcome Score–Activities of Daily Living (HOS-ADL) at a minimum of 2 years postoperatively. Secondary outcome measures included the HOS-Sports and modified Harris Hip Score (mHHS). Results: The mean preoperative LCEA differed significantly between groups (23.4° ± 1.5° for borderline dysplastic, 32.5° ± 3.8° for normal coverage; P < .001). The borderline dysplastic group had a higher percentage of female patients than the normal coverage group (27/36 [75%] vs 177/312 [57%], respectively; P = .048). There were no differences in other preoperative demographics and radiographic parameters. At a minimum 2 years after hip arthroscopic surgery (mean follow-up, 2.6 ± 0.6 years), both groups demonstrated significant improvements in all patient-reported outcome scores ( P < .001 in all cases). There were no significant differences between the borderline dysplastic and normal coverage groups in final outcome scores, score improvements, or percentage of patients experiencing clinically significant improvements. One patient in the borderline dysplastic group (3%) underwent revision hip arthroscopic surgery, and none underwent total hip arthroplasty during the follow-up period. There were no differences between the borderline dysplastic and normal coverage groups with regard to subsequent surgery. Female patients in the borderline dysplastic group had greater improvements in the mean HOS-ADL (25.9 ± 16.3 vs 10.8 ± 18.5, respectively; P = .05) and mHHS (27.9 ± 12.9 vs 8.1 ± 19.0, respectively; P = .005) compared with male patients in the borderline dysplastic group, but male and female patients did not differ in outcomes for the normal coverage group. Conclusion: Patients who underwent hip arthroscopic surgery for FAI with capsular plication experienced significant clinical improvements with low rates of subsequent surgery, regardless of whether their acetabulum had borderline dysplasia or normal coverage.

Abstract Purpose The aim of this systematic review was to evaluate the trends in the literature regarding surgical treatment for femoroacetabular impingement syndrome (FAIS) and to present which patient-reported outcome-measures (PROMs) and surgical approaches are included. Methods This systematic review was conducted with the PRISMA guidelines. The literature search was performed on PubMed and Embase, covering studies from 1999 to 2020. Inclusion criteria were clinical studies with surgical treatment for FAIS, the use of PROMs as evaluation tool and studies in English. Exclusion criteria were studies with patients < 18 years, cohorts with < 8 patients, studies with primarily purpose to evaluate other diagnoses than FAIS and studies with radiographs as only outcomes without using PROMs. Data extracted were author, year, surgical intervention, type of study, level of evidence, demographics of included patients, and PROMs. Results The initial search yielded 2,559 studies, of which 196 were included. There was an increase of 2,043% in the number of studies from the first to the last five years (2004–2008)—(2016–2020). There were 135 (69%) retrospective, 55 (28%) prospective and 6 (3%) Randomized Controlled Trials. Level of evidence ranged from I-IV where Level III was most common (44%). More than half of the studies (58%) originated from USA. Arthroscopic surgery was the most common surgical treatment (85%). Mean follow-up was 27.0 months (± 17 SD), (range 1.5–120 months). Between 1–10 PROMs were included, and the modified Harris Hip Score (mHHS) was most commonly used (61%). Conclusion There has been a continuous increase in the number of published studies regarding FAIS with the majority evaluating arthroscopic surgery. The mHHS remains being the most commonly used PROM.

Abstract Capsulotomy is necessary to facilitate instrument manoeuvrability within the joint capsule in many arthroscopic hip surgical procedures. In cases where a clear indication for capsular closure does not exist, surgeon’s preference and experience often determines capsular management. The purpose of this study was to assess the influence of capsular closure on clinical outcome scores and satisfaction in patients who underwent hip arthroscopy surgery for femoroacetabular impingement (FAI) and labral tear. Data were prospectively collected and retrospectively analysed for hip arthroscopy surgeries with a minimum 2 years follow-up. Patients with developmental dysplasia of the hip, previous back or hip surgeries, and degenerative changes to this hip and secondary gains were excluded. Demographic data, intraoperative findings and patient-reported outcome scores were recorded, including the Modified Harris Hip Score (MHHS) and Hip Outcome Score (HOS). A total of 29 and 35 patients were included in the non-closure and closure groups, respectively. The mean follow-up time was over 3 years for both groups. The mean pre-operative and post-operative HOS scores and MHHS scores did not significantly differ between groups (pre-operative HOS: 65.6 and 66.3, P = 0.898; post-operative HOS: 85.4 and 87.2, P = 0.718; pre-operative MHHS: 63.2 and 58.4, P = 0.223; post-operative MHHS: 85.7 and 88.7, P = 0.510). Overall patient satisfaction did not differ significantly between groups (non-closure 86.3%, closure group 88.6%; P = 0.672). Capsular closure did not significantly influence satisfaction or clinical outcome scores in patients who underwent arthroscopic hip surgery for FAI or labral tear.

Background: The Patient-Reported Outcomes Measurement Information System (PROMIS) is being increasingly evaluated for use in orthopaedic surgery. The performance of the PROMIS in patients undergoing hip preservation surgery is unknown. Purpose: To investigate the psychometric performance of the PROMIS compared with legacy patient-reported outcome measures (PROMs) in patients indicated for hip arthroscopic surgery for femoroacetabular impingement syndrome (FAIS). Study Design: Cohort study (diagnosis); Level of evidence, 2. Methods: Data from consecutive patients who underwent primary hip arthroscopic surgery between January and October 2018 for the treatment of FAIS were collected and analyzed. Baseline data, including preoperative PROM scores and demographics, were recorded. PROMs included the PROMIS Physical Function (PF), the Hip Outcome Score (HOS), the modified Harris Hip Score (mHHS), the International Hip Outcome Tool–12 (iHOT-12), and the Veterans RAND 12-item health survey (VR-12). Pearson and Spearman coefficient analyses were used to identify correlations between continuous and noncontinuous variables, respectively. Correlation was defined as excellent (>0.80), very good (0.71-0.80), good (0.61-0.70), fair (0.41-0.60), or poor (0.21-0.40). A multivariate linear regression analysis was used to identify preoperative predictors of having higher preoperative PROMIS scores. Results: A total of 197 patients with a mean age and body mass index (BMI) of 32.8 ± 12.6 years and 25.7 ± 5.6 kg/m2, respectively, were included in the final analysis. There were no ceiling or floor effects for the PROMIS PF score observed in the study group. With regard to hip-specific measures, PROMIS PF scores demonstrated excellent correlation with HOS–Activities of Daily Living ( r = 0.801; P < .001) scores, very good correlation with mHHS ( r = 0.721; P < .001) and iHOT-12 ( r = 0.722; P < .001) scores, and good correlation with HOS–Sports Specific ( r = 0.675; P < .001) scores. With regard to general health–related quality of life (HRQoL) measures, PROMIS PF scores demonstrated very good correlation with VR-12 mental ( r = 0.721; P < .001) scores, good correlation with VR-12 physical ( r = 0.618; P < .001) scores, and poor correlation with visual analog scale for pain ( r = –0.365; P < .001) scores. Patients who reported being physically active were more likely to have a higher preoperative PROMIS score (β = 3.216; P = .004). Lower PROMIS scores were found in patients with a higher BMI (β = –0.236; P = .005) and in female patients (β = –2.608; P = .014). Conclusion: In patients with FAIS, the preoperative PROMIS PF scores demonstrated excellent to good correlation with legacy hip-specific instruments as well as with HRQoL measures. No ceiling or floor effects were identified. Notably, of the hip-specific PROMs administered, the PROMIS PF demonstrated the weakest correlation with the HOS–Sports Specific subscale. Physical activity, BMI, and sex were predictors of preoperative PROMIS scores in our patient population.
