To determine the association between femoral torsion and anterior cruciate ligament (ACL) rupture and determine the level of torsion using magnetic resonance imaging (MRI).
The medical records of patients who were diagnosed with ACL injury were reviewed retrospectively. This descriptive epidemiological study included 2344 patients. MRI scans were examined and patients with femur and knee MRI scans obtained at the same time were identified (ACL-deficient group). Twenty-eight of them had femur and knee MRI scans because of an incidental benign lesion in the distal femur. Patients who were diagnosed with enchondroma were followed up by MRI evaluation of the femur and were randomly selected as controls. Supratrochanteric torsion (STT), infratrochanteric torsion (ITT), and femoral anteversion (FA) were measured by orthopedic surgeons with at least 5 years of experience.
Age, sex, and side properties were similar in both groups. The mean FA values were 19.4 ± 3.0 degrees and 11.9 ± 2.0 degrees in the ACL-deficient and control groups, respectively (p < 0.001). STT was similar in the ACL-deficient and control groups [mean: 38.2 ± 4.3 and 37.7 ± 3.3, respectively, (n.s.)]. ITT was increased in the ACL-deficient group compared with the control group (mean - 18.8 ± 4.3 and - 25.8 ± 3.8, respectively; p < 0.001).
According to our results, increased FA was associated with ACL rupture. Further, the torsional abnormality was developed from the ITT. We concluded that each ACL-deficient patient should be assessed by a clinician for torsional abnormality using physical examination.

通过磁共振成像（MRI）确定股骨扭转与前交叉韧带（ACL）撕裂之间的关系，并确定扭转程度。
回顾性分析诊断为 ACL 损伤的患者的病历。本描述性流行病学研究共纳入 2344 名患者。对 MRI 扫描进行检查，并确定同时获得股骨和膝关节 MRI 扫描的患者（ACL 缺失组）。其中 28 例因股骨远端良性病变进行股骨和膝关节 MRI 扫描。诊断为内生软骨瘤的患者通过 MRI 评估股骨进行随访，并随机选择作为对照组。由至少具有 5 年经验的矫形外科医生测量转子下扭转（STT）、转子间扭转（ITT）和股骨前倾角（FA）。
两组的年龄、性别和侧别特征相似。ACL 缺失组和对照组的 FA 平均值分别为 19.4±3.0 度和 11.9±2.0 度（p<0.001）。ACL 缺失组和对照组的 STT 相似[平均值分别为 38.2±4.3 和 37.7±3.3，无统计学差异（n.s.）]。与对照组相比，ACL 缺失组的 ITT 增加（平均值分别为-18.8±4.3 和-25.8±3.8，p<0.001）。
根据我们的结果，增加的 FA 与 ACL 撕裂有关。此外，扭转异常是从 ITT 发展而来的。我们得出结论，每个 ACL 缺失的患者都应由临床医生通过体格检查评估扭转异常。
