A growing number of studies have examined return to sport in competitive athletes after undergoing hip arthroscopy for femoroacetabular impingement syndrome (FAIS); however, few have evaluated the rate of achieving meaningful clinical outcomes in this group.
To determine if competitive athletes (professional, semiprofessional, or collegiate) have better 2-year patient-reported outcomes and achieve the minimal clinically important difference (MCID) and substantial clinical benefit at higher rates when compared with nonathletes undergoing hip arthroscopy for the treatment of FAIS.
Cohort study; Level of evidence, 3.
The study was a retrospective analysis of all consecutive patients who identified as either a competitive athlete or a nonathlete and had undergone hip arthroscopy for FAIS by a single fellowship-trained surgeon between January 2012 and April 2017. Patients in the 2 groups were matched 1:2 by age, sex, and body mass index. Baseline and clinical outcomes, including the Hip Outcome Score-Activities of Daily Living, Hip Outcome Score-Sports Subscale (HOS-SS), modified Harris Hip Score, and international Hip Outcome Tool-12, were collected preoperatively and at 2 years postoperatively and compared between the groups. The MCID and substantial clinical benefit were calculated for each group separately and compared using chi-square analysis.
A total of 59 competitive athletes and 118 nonathletes were included in the final analysis. Most of the competitive athletes were soccer players (23.7%), followed by softball players (10.2%) and runners (10.2%). Postoperative score comparison between competitive athletes and nonathletes demonstrated a statistically significant difference in the HOS-SS (mean ± SD, 84.5 ± 19.0 vs 76.1 ± 23.8; = .02). Meaningful outcome analysis demonstrated that competitive athletes had a higher rate of achieving the HOS-SS threshold for the MCID (97.4% vs 82.5%; = .021). There was no other difference in frequency of achieving the threshold for any other meaningful clinical outcome between the groups.
Hip arthroscopy for the treatment of FAIS in competitive athletes and nonathletes produced clinically meaningful outcomes in both patient groups. However, competitive athletes achieved the MCID on the HOS-SS at higher rates than nonathletes and had significantly higher scores at 2 years postoperatively on the HOS-SS.
越来越多的研究检查了髋关节镜治疗股骨髋臼撞击综合征（FAIS）后竞技运动员重返运动的情况；然而，很少有研究评估该组患者获得有意义的临床结果的比例。
确定与接受髋关节镜治疗 FAIS 的非运动员相比，竞技运动员（专业、半专业或大学生）是否具有更好的 2 年患者报告结果，并以更高的比例达到最小临床重要差异（MCID）和显著临床获益。
队列研究；证据水平，3 级。
该研究回顾性分析了 2012 年 1 月至 2017 年 4 月期间由同一位接受过 fellowship培训的外科医生对 FAIS 进行髋关节镜治疗的所有连续患者，患者分为竞技运动员和非运动员。通过年龄、性别和体重指数将两组患者进行 1:2 匹配。收集术前和术后 2 年的基线和临床结果，包括髋关节结果评分-日常生活活动、髋关节结果评分-运动亚量表（HOS-SS）、改良 Harris 髋关节评分和国际髋关节结果工具-12，并在两组之间进行比较。分别计算每个组的 MCID 和显著临床获益，并使用卡方分析进行比较。
共纳入 59 名竞技运动员和 118 名非运动员进行最终分析。大多数竞技运动员是足球运动员（23.7%），其次是垒球运动员（10.2%）和跑步运动员（10.2%）。竞技运动员和非运动员之间的术后评分比较显示，HOS-SS 存在统计学显著差异（平均±标准差，84.5±19.0 比 76.1±23.8； =.02）。有意义的结果分析表明，竞技运动员达到 HOS-SS MCID 阈值的比例更高（97.4%比 82.5%； =.021）。两组之间其他任何有意义的临床结果的阈值达到频率均无差异。
髋关节镜治疗 FAIS 对竞技运动员和非运动员均能产生有临床意义的结果。然而，与非运动员相比，竞技运动员在 HOS-SS 上达到 MCID 的比例更高，并且在术后 2 年时 HOS-SS 的得分显著更高。
