Background:Hip arthroscopy has proved successful in treating femoroacetabular impingement syndrome (FAIS) in patients with and without borderline hip dysplasia (BHD). Despite a high prevalence of BHD in patients who participate in sports with high flexibility requirements, a paucity of literature evaluates the efficacy of hip arthroscopy in treating FAIS in flexibility sport athletes with BHD.Purpose:To compare minimum 2-year patient-reported outcomes (PROs) and achievement of clinically significant outcomes in flexibility sport athletes with BHD undergoing primary hip arthroscopy for FAIS with capsular plication with results in flexibility sport athletes without dysplasia.Study Design:Cohort study; Level of evidence, 3.Methods:Data were prospectively collected for patients undergoing primary hip arthroscopy for FAIS with BHD, defined as a lateral center-edge angle of 18° to 25°, who reported participation in a sport with a high flexibility requirement, including dance, gymnastics, figure skating, yoga, cheerleading, and martial arts, according to previous literature. These patients were matched 1:2 to flexibility sport athletes without dysplasia, controlling for age, sex, and body mass index. Preoperative and minimum 2-year postoperative PROs were collected and compared between groups. Cohort-specific minimal clinically important difference and patient acceptable symptom state achievement was compared between groups.Results:In total, 52 flexibility sport athletes with BHD were matched to 104 flexibility sport athletes without BHD. Both groups showed similar sport participation ( P = .874) and a similar level of competition ( P = .877). Preoperative lateral center-edge angle (22.2°± 1.6° vs 31.5°± 3.9°; P < .001) and Tönnis angle (10.9°± 3.7° vs 5.8°± 4.4°; P < .001) differed between groups. Capsular plication was performed in all cases. Both groups achieved significant improvement in all PROs ( P < .001) with no differences in postoperative PROs between groups ( P≥ .147). High minimal clinically important difference (BHD group: 95.7%; control group: 94.8%) and patient acceptable symptom state (BHD group: 71.7%; control group: 72.2%) achievement for any PRO was observed with no differences between groups ( P≥ .835).Conclusion:Flexibility sport athletes with BHD achieved similar outcomes as those of flexibility sport athletes without BHD after hip arthroscopy for FAIS with capsular plication.

患有临界髋关节发育不良的灵活性运动运动员因股髋臼撞击综合征进行髋关节镜检查后的结果：至少 2 年随访的倾向匹配分析

背景：髋关节镜检查已被证明可以成功治疗患有或不患有交界性髋关节发育不良（BHD）的股骨髋臼撞击综合征（FAIS）。尽管参加灵活性要求高的运动的患者中 BHD 的患病率很高，但很少有文献评估髋关节镜检查对患有 BHD 的灵活性运动运动员治疗 FAIS 的疗效。 目的：比较至少 2 年患者报告的结果（ PROs），并在患有 BHD 的灵活性运动运动员中接受初次髋关节镜检查以进行 FAIS 联合囊膜折叠术，并在没有发育不良的灵活性运动运动员中取得临床显着结果。 研究设计：队列研究；证据级别，3。方法：前瞻性收集因 FAIS 接受初次髋关节镜检查并伴有 BHD 的患者的数据，定义为横向中心边缘角为 18° 至 25°，他们报告参加了具有高灵活性要求的运动，根据之前的文献，包括舞蹈、体操、花样滑冰、瑜伽、啦啦队和武术。这些患者与无发育不良的柔韧运动运动员以 1:2 的比例进行匹配，并控制了年龄、性别和体重指数。收集术前和术后至少 2 年的 PRO，并进行组间比较。比较组间特定队列的最小临床重要差异和患者可接受的症状状态成就。结果：总共，52 名患有 BHD 的灵活性运动运动员与 104 名不具有 BHD 的灵活性运动运动员相匹配。两组都表现出相似的运动参与度 (P = .874) 和相似的竞争水平 (P = .877)。术前侧向中心边缘角（22.2°± 1.6° vs 31.5°± 3.9°；P < .001）和 Tönnis 角（10.9°± 3.7° vs 5.8°± 4.4°；P < .001）在各组之间存在差异。所有病例均进行了包膜折叠术。两组的所有 PRO 均取得显着改善 ( P < .001)，但组间术后 PRO 没有差异 ( P≥ .147)。观察到任何 PRO 的高最小临床重要差异（BHD 组：95.7%；对照组：94.8%）和患者可接受的症状状态（BHD 组：71.7%；对照组：72.2%）成就，组间没有差异（ P≥ .835).结论：具有 BHD 的灵活性运动运动员在进行 FAIS 关节囊折叠术髋关节镜检查后取得了与不具有 BHD 的灵活性运动运动员相似的结果。
