This study used the NCAA Injury Surveillance System to compare ACL injury rates between male and female collegiate soccer and basketball players over 5 years. It tested whether women sustain ACL injuries more often than men in matched sports, and characterized the mechanisms behind those injuries.
When a young female athlete in a cutting-and-pivoting sport presents with an acute knee injury, keep ACL disruption high on your differential. This paper quantified what smaller studies only hinted at: women carry a 2- to 4-fold higher ACL injury rate than men in the same sport, and the excess is driven by noncontact mechanisms.
That mechanism detail matters. Because the injury happens on landing, cutting, and deceleration rather than through contact, the prevention target is neuromuscular control, not equipment or contact rules.
The cited 89% reduction from movement retraining is the mental model to carry forward: a flexed knee lets the hamstrings resist anterior tibial translation and keeps the ACL out of vulnerable terminal extension.
The authors are careful to call the cause multifactorial and unresolved, spanning extrinsic factors (strength, skill, shoe-surface) and intrinsic factors (notch width, laxity, alignment). This paper is the foundational epidemiology behind the entire ACL prevention and screening literature that followed.
