The aims of this narrative review were to summarise trunk motion and external trunk perturbation observed in anterior cruciate ligament (ACL) injury videos and to review the association between trunk motion and ACL loading variables in controlled jump-landing and cutting tasks in non-injured populations. Video analyses have shown limited trunk flexion and increased trunk lateral bending towards the injured leg are associated with increased risk of ACL injuries, while trunk axial rotation away from the injured leg is more frequent than rotation towards the injured leg. Contact with the trunk before and at the time of the injury is common and might increase the risk of ACL injury. Controlled jump-landing and cutting studies have shown that limited trunk flexion and increased trunk lateral bending are associated with increased ACL loading. However, the findings of trunk axial rotation are not consistent with most video analyses. Mid-flight external trunk perturbation could increase ACL loading variables for one leg and is consistent with the videos of trunk-contact ACL injuries. These findings may help understand the role of trunk motion on primary ACL injury mechanisms and improve ACL injury screening tasks and ACL injury prevention strategies with the consideration of trunk motion.
本叙述性综述的目的是总结在前交叉韧带（ACL）损伤视频中观察到的躯干运动和外部躯干扰动，并回顾在未受伤人群的受控跳落和切入任务中躯干运动与ACL负荷变量之间的关联。视频分析表明，有限的躯干屈曲以及向受伤腿方向增加的躯干侧屈与ACL损伤风险增加有关，而躯干轴向远离受伤腿的旋转比朝向受伤腿的旋转更频繁。在受伤前和受伤时与躯干接触很常见，这可能会增加ACL损伤的风险。受控跳落和切入研究表明，有限的躯干屈曲和增加的躯干侧屈与ACL负荷增加有关。然而，躯干轴向旋转的研究结果与大多数视频分析不一致。飞行中外部躯干扰动可能会增加单腿的ACL负荷变量，这与躯干接触性ACL损伤的视频一致。这些发现可能有助于理解躯干运动在原发性ACL损伤机制中的作用，并在考虑躯干运动的情况下改进ACL损伤筛查任务和ACL损伤预防策略。
