Considering that an athlete performs at-risk sports activities countless times throughout the course of his or her career prior to the instance of anterior cruciate ligament (ACL) injury, one may conclude that non-contact ACL injury is a rare event. Nevertheless, the overall number of non-contact ACL injuries, both in the US and worldwide, remains alarming due to the growing number of recreational and professional athletes participating in high-risk activities. To date, numerous non-contact ACL injury mechanisms have been proposed, but none provides a detailed picture of sequence of events leading to injury and the exact cause of this injury remains elusive. In this perspective article, we propose a new conception of non-contact ACL injury mechanism that comprehensively integrates risk factors inside and outside the knee joint. The proposed mechanism is robust in the sense that it is biomechanically justifiable and addresses a number of confounding issues related to ACL injury.
考虑到运动员在 ACL 损伤之前的职业生涯中会无数次地进行高风险运动,人们可能会得出这样的结论:非接触性 ACL 损伤是一种罕见的事件。然而,由于越来越多的娱乐和职业运动员参与高风险活动,美国和全球范围内的非接触性 ACL 损伤总数仍然令人震惊。迄今为止,已经提出了许多非接触性 ACL 损伤机制,但没有一种机制能详细描述导致损伤的事件序列,也没有明确这种损伤的确切原因。在这篇观点文章中,我们提出了一种新的非接触性 ACL 损伤机制概念,该机制全面整合了膝关节内外的危险因素。所提出的机制是稳健的,因为它在生物力学上是合理的,并解决了与 ACL 损伤相关的许多混杂问题。
