To evaluate femoral and acetabular morphology in patients who underwent anterior cruciate ligament reconstruction (ACLR).
A retrospective review of a prospectively collected ACL registry was performed to identify patients with pelvis radiographs before undergoing either primary or revision ACLR between January 2010 and August 2020. Alpha angle (AA), head-neck offset ratio (HNOR), lateral center edge angle (LCEA), and crossover sign (COS) were measured on the operative side. Values were compared to a negative control group that did not significantly differ in age, sex, or body mass index. Univariate analysis and Pearson's correlation coefficient were used to compare groups with significance defined as < .05.
In total, 114 patients were included (ACL, n = 38; control, n = 76). Eleven primary and 27 revision ACL reconstructions were identified. The mean AA in patients undergoing primary ACL reconstruction was higher than control (67.45° ± 11.30° vs 51.5° ± 10.8°, < .001). A significantly elevated AA was also found in those undergoing revision ACL surgery (61.8° ± 7.51° vs 51.5° ± 10.8°, < .001). In addition, the HNOR was significantly lower in the ACL group (0.12 ± 0.03 vs 0.14 ± 0.04, = .0304). Acetabular morphology was similar between groups (LCEA, ACL 31.97° ± 5.04° vs control 30.01° ± 5.17°, = .0549; COS, ACL 9 of 38 (23.7%) vs control 18 of 76 (23.7%), = 1.00).
An association exists between radiographic cam morphology of the hip and patients who previously underwent ACLR.

评估接受前交叉韧带重建术（ACLR）患者的股骨和髋臼形态。
对前瞻性收集的ACL登记册进行回顾性研究，以确定在2010年1月至2020年8月期间接受初次或翻修ACLR之前有骨盆X光片的患者。在手术侧测量阿尔法角（AA）、头颈偏移率（HNOR）、外侧中心边缘角（LCEA）和交叉征（COS）。将这些值与年龄、性别或体重指数无显著差异的阴性对照组进行比较。采用单因素分析和Pearson相关系数对组间进行比较，显著性定义为<0.05。
共纳入114例患者（ACL组，n = 38；对照组，n = 76）。确定了11例初次和27例翻修ACL重建手术。接受初次ACL重建的患者的平均AA高于对照组（67.45°±11.30°对51.5°±10.8°，<0.001）。在接受翻修ACL手术的患者中也发现AA显著升高（61.8°±7.51°对51.5°±10.8°，<0.001）。此外，ACL组的HNOR显著较低（0.12±0.03对0.14±0.04，P = 0.0304）。两组间髋臼形态相似（LCEA，ACL组31.97°±5.04°对对照组30.01°±5.17°，P = 0.0549；COS，ACL组38例中有9例（23.7%）对对照组76例中有18例（23.7%），P = 1.00）。
髋关节影像学凸轮形态与既往接受ACLR的患者之间存在关联。
