This prospective cohort study enrolled 205 female soccer, basketball, and volleyball players who underwent 3D biomechanical analysis of a drop vertical jump before their competitive seasons. It asks whether knee kinematics and kinetics during landing can identify which athletes will subsequently suffer ACL rupture.
When a female athlete walks into your clinic after an ACL tear, this paper explains why it happened — and why her teammate is next.
Before Hewett 2005, ACL injury in female athletes was attributed to anatomy, hormones, and bad luck. This study was the first to prospectively prove that a measurable, modifiable movement pattern. Dynamic knee valgus during landing. Predicts who ruptures before it happens.
In practice: screen female athletes in high-risk sports for coronal plane control deficits, not just flexibility or strength. A woman who collapses into valgus on a drop jump has a biomechanical signature that predicts ACL injury with nearly 80% sensitivity.
This work is the scientific foundation for every ACL prevention program you use. PEP, FIFA 11+, JUMP-ACL. The goal of those programs is to reduce knee abduction moment at landing. If a patient is non-compliant with prevention training, this paper gives you the numbers to explain why it matters.
