Anterior cruciate ligament (ACL) disruption is a common injury that is detrimental to an athlete's quality of life. Determining the mechanisms that cause ACL injury is important in order to develop proper interventions. A failure locus defined as various combinations of loadings and movements, internal/external rotation of femur and valgus and varus moments at a 25(o) knee flexion angle leading to ACL failure was obtained. The results indicated that varus and valgus movements were more dominant to the ACL injury than femoral rotation. Also, Von Mises stress in the lateral tibial cartilage during the valgus ACL injury mechanism was 83% greater than that of the medial cartilage during the varus mechanism of ACL injury. The results of this study could be used to develop training programmes focused on the avoidance of the described combination of movements which may lead to ACL injury.
前交叉韧带（ACL）断裂是一种常见损伤，会对运动员的生活质量造成不利影响。确定导致ACL损伤的机制对于制定适当的干预措施很重要。获得了一个失效轨迹，其定义为在25°膝关节屈曲角度下导致ACL失效的各种载荷和运动组合、股骨的内/外旋转以及外翻和内翻力矩。结果表明，与股骨旋转相比，外翻和内翻运动对ACL损伤的影响更大。此外，在ACL损伤的外翻机制中，外侧胫骨软骨的冯·米塞斯应力比ACL损伤的内翻机制中内侧软骨的应力大83%。本研究结果可用于制定侧重于避免可能导致ACL损伤的上述运动组合的训练计划。
