BACKGROUND 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. PURPOSE 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. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS 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. RESULTS 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; P = .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%; P = .021). There was no other difference in frequency of achieving the threshold for any other meaningful clinical outcome between the groups. CONCLUSION 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.

比较竞争性运动员与非运动员进行髋关节镜检查治疗髋臼髋臼冲击综合征的结果。

背景技术越来越多的研究已经检查了髋关节镜检查股骨髋臼撞击综合征（FAIS）后竞技运动员的运动能力；但是，很少有人评估该组达到有意义的临床结果的速度。目的确定竞技运动员（专业，半专业或大学运动员）是否具有更好的两年患者报告的结局，并与接受髋关节镜检查的非运动员相比以更高的比率获得最小的临床重要差异（MCID）和实质性的临床收益FAIS。研究设计队列研究；证据水平3。方法该研究是对2012年1月至2017年4月间由一名受过研究金培训的外科医生接受过FAIS髋关节镜检查的所有连续患者的回顾性分析，这些患者被确定为竞技运动员或非运动员。 ：2按年龄，性别和体重指数排序。在术前和术后2年收集基线和临床结果，包括日常生活中的髋关节成果活动度，髋关节成果运动量表（HOS-SS），改良的Harris髋关节分数和国际髋关节成果工具12。组之间比较。分别计算每组的MCID和实质性临床获益，并使用卡方分析进行比较。结果最终分析中总共包括59名竞技运动员和118名非运动员。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的术后评分比较显示，HOS-SS的差异具有统计学意义（均值±SD，84.5±19.0 vs 76.1±23.8； P = .02）。有意义的结果分析表明，竞技运动员达到MCID的HOS-SS阈值的比率更高（97.4％对82.5％； P = .021）。两组之间达到任何其他有意义的临床结果的阈值的频率没有其他差异。结论髋关节镜在竞争性运动员和非运动员中治疗FAIS均在两个患者组中产生了临床上有意义的结果。然而，
