摘要

Over 120,000 anterior cruciate ligament (ACL) injuries occur annually in the United States, mainly affecting the young athletic population. Non-contact injuries are reported to be the predominant mechanism of ACL injury (＞70% of ACL injuries), which often occur during landing with high ground reaction forces, muscle forces and segmental inertia. An improved understanding of the mechanisms underlying noncontact ACL injury and inciting events can be used to improve current prevention strategies and decrease the risk of early-onset osteoarthritis. Previous biomechanical and video analysis studies have demonstrated that anterior tibial translation (ATT), knee valgus and internal tibial rotation (ITR) are associated with non-contact ACL injuries. While the effects of these factors on ACL injury risk have been extensively studied, there is still controversy and debate about the timing in which these motions occur and reach maximum values during a jump landing task. The current study aimed to investigate interactions between tibio-femoral joint kinematics and ACL strain through a detailed cadaveric simulation of the knee biomechanical response during landing from a jump. For this purpose, instrumented cadaveric limbs were used to simulate bi-pedal landing following a jump utilizing a novel testing apparatus.
