在非接触性前交叉韧带（ACL）损伤期间，躯干和膝关节在冠状面和矢状面中的组合定位以前没有报道。在ACL损伤期间，女性运动员表现出更大的躯干外侧和膝关节外展角比ACL损伤的男性运动员和未受伤的女性运动员。横断面对照队列设计。分析来自23个冠状面（10名女性和7名男性ACL受伤球员以及6名女性对照）或28个矢状面视频的静态捕获，执行类似的着陆和切割任务。显著性设定为p ≤ 0.05。在ACL损伤期间，女性运动员的躯干外侧和膝关节外展角高于男性运动员（p ≤ 0.05），并有大于女性对照组的趋势（分别为p = 0.16，0.13）。与女性对照组相比，ACL损伤的女性运动员躯干前倾程度更低（平均（SD）初始接触（IC）：1.6（9.3）° vs 14.0（7.3）°，p ≤ 0.01）。女运动员着陆时，在类似的着陆和切割任务中，前交叉韧带损伤时的躯干外侧运动和膝关节外展比男运动员或对照组女性更大。从ACL损伤的视频证据中观察到，外侧躯干和膝关节外展运动是女性运动员ACL损伤机制的重要组成部分。
The combined positioning of the trunk and knee in the coronal and sagittal planes during non-contact anterior cruciate ligament (ACL) injury has not been previously reported. During ACL injury female athletes demonstrate greater lateral trunk and knee abduction angles than ACL-injured male athletes and uninjured female athletes. Cross-section control-cohort design. Analyses of still captures from 23 coronal (10 female and 7 male ACL-injured players and 6 female controls) or 28 sagittal plane videos performing similar landing and cutting tasks. Significance was set at p ≤ 0.05. Lateral trunk and knee abduction angles were higher in female compared to male athletes during ACL injury (p ≤ 0.05) and trended toward being greater than female controls (p = 0.16, 0.13, respectively). Female ACL-injured athletes showed less forward trunk lean than female controls (mean (SD) initial contact (IC): 1.6 (9.3)° vs 14.0 (7.3)°, p ≤ 0.01). Female athletes landed with greater lateral trunk motion and knee abduction during ACL injury than did male athletes or control females during similar landing and cutting tasks. Lateral trunk and knee abduction motion are important components of the ACL injury mechanism in female athletes as observed from video evidence of ACL injury.
