Abstract：
UNASSIGNED: The function of the iliocapsularis (IC) muscle is still unclear. Previous studies have reported that the cross-sectional area of the IC may be useful in identifying borderline developmental dysplasia of the hip (BDDH).
UNASSIGNED: To evaluate the pre- to postoperative changes in IC cross-sectional area in patients with femoroacetabular impingement (FAI) and to determine if there are any associations with clinical outcomes after hip arthroscopy.
UNASSIGNED: Cohort study; Level of evidence, 3.
UNASSIGNED: The authors retrospectively evaluated patients who underwent arthroscopic surgery for FAI at a single institution between January 2019 and December 2020. Patients were divided into 3 groups according to lateral center-edge angle: BDDH group (20°-25°), control group (25°-40°), and pincer group (>40°). Supine anteroposterior hip radiographs, 45° Dunn view radiographs, computed tomography scans, and magnetic resonance imaging (MRI) scans were obtained for all patients preoperatively and postoperatively. The cross-sectional areas of the IC and the rectus femoris (RF) were measured on an axial MRI slice at the level of the femoral head center. Preoperative and final follow-up scores on the visual analog scale for pain and the modified Harris Hip Score (mHHS) were compared between groups with the independent-samples t test.
UNASSIGNED: A total of 141 patients (mean age, 38.5 years; 64 male, 77 female) were included. The preoperative IC-to-RF ratio of the BDDH group was significantly higher than that of the pincer group (P < .05). In the BDDH group, there was significant pre- to postoperative decrease in IC cross-sectional area and the IC-to-RF ratio (P < .05 for both) as well as a significant correlation between the preoperative IC cross-sectional area and the postoperative mHHS (r = 0.434; P = .027).
UNASSIGNED: Patients with BDDH had a significantly higher preoperative IC-to-RF ratio than patients with pincer morphology. A higher preoperative IC cross-sectional area was associated with better postoperative patient-reported outcomes after arthroscopy for the treatment of FAI combined with BDDH.

摘要：
未经授权：髂囊肌（IC）的功能仍不清楚。先前的研究报道，IC的横截面积可用于识别髋关节的临界发育异常（BDDH）。
UNASSIGNED：评估股髋臼撞击（FAI）患者IC横截面积的术前术后变化，并确定是否与髋关节镜检查后的临床结果相关。
未经批准：队列研究；证据水平，3.
UNASSIGNED：作者回顾性评估了2019年1月至2020年12月在单一机构接受FAI关节镜手术的患者。根据侧中边缘角度分为3组：BDDH组（20°-25°），对照组（25°-40°），夹钳组(>40°)。仰卧位前后髋部X光片，45°邓恩视图射线照片，计算机断层扫描,术前和术后对所有患者进行磁共振成像（MRI）扫描。在股骨头中心水平的轴向MRI切片上测量IC和股直肌（RF）的横截面积。术前和最终随访的疼痛视觉模拟评分和改良的Harris髋关节评分（mHHS）通过独立样本t检验比较两组之间的评分。
未经批准：总共141名患者（平均年龄，38.5岁；男性64岁，包括77名女性）。BDDH组术前IC-RF比值明显高于夹钳组(P<0.05)。在BDDH组中，术前术后IC横截面积和IC-RF比值显著下降(两者P<.05),术前IC横截面积和术后mHHS之间也存在显著相关性(r=0.434;P=.027).
UNASSIGNED：BDDH患者术前IC-RF比值明显高于钳形患者。术前IC横截面积较高与关节镜治疗FAI联合BDDH后患者报告的预后较好相关。
