Non-contact anterior cruciate ligament (ACL) injuries occur with rapid decelerations and pivoting. A recent injury to a high-level National Basketball Association (NBA) player demonstrated neuromuscular control and injury-sparing mechanisms that resulted in only minor ligament injury to the medial collateral ligament. We analyzed biomechanical mechanisms via publically available orthogonal 2-D video to demonstrate how this potential ACL injury was averted. Analysis of the knee injury mechanism demonstrated that the NBA player experienced low ground reaction force, high sagittal plane flexion, and maintenance of frontal plane stability with neuromuscular control. The outcome of these factors inhibited dynamic valgus collapse of the knee throughout the fall, avoiding ACL injury - a potentially career-altering injury. Many athletes, professional and recreational, will be subjected to similar mechanisms of injury and will have improved outcomes if they can successfully utilize preventive strategies of neuromuscular control to limit injury mechanisms.
非接触性前交叉韧带（ACL）损伤发生在快速减速和 pivoting 动作时。一名近期受伤的美国职业篮球联赛（NBA）高水平球员展示了神经肌肉控制和损伤预防机制，这使得内侧副韧带仅受轻微韧带损伤。我们通过公开的正交二维视频分析生物力学机制，以证明这种潜在的 ACL 损伤是如何避免的。对膝关节损伤机制的分析表明，这位 NBA 球员地面反作用力较低，矢状面屈曲度较高，并且通过神经肌肉控制维持了额状面稳定性。这些因素的结果是在整个跌倒过程中抑制了膝关节的动态外翻塌陷，避免了 ACL 损伤——一种可能改变职业生涯的损伤。许多职业和业余运动员都会经历类似的损伤机制，如果他们能够成功运用神经肌肉控制的预防策略来限制损伤机制，将会有更好的结果。
