This case series analyzed video footage of 57 consecutive ACL injuries in professional female soccer players across six top leagues (2017-2020). It characterizes the injury mechanism, situational context, and kinematics to identify targets for sex-specific prevention programs. Biomechanical analysis was possible in 29 cases using frame-by-frame evaluation by three independent blinded reviewers.
Female soccer players suffer ACL injuries at 2-3 times the rate of male players, yet until this study, no systematic video analysis had been performed in an exclusively professional female cohort — prevention programs had been largely extrapolated from male data.
When a female soccer player tears her ACL, the injury almost certainly occurred during a defensive action. Specifically pressing, decelerating toward an opponent, or regaining balance after kicking. This is where prevention program drills should be concentrated, not just generic jump-landing tasks.
The timing data changes how you think about warm-up: nearly two-thirds of injuries happen in the first 45 minutes of play, not late in the game when fatigue is maximal. High neuromuscular readiness at kickoff matters as much as endurance conditioning.
The biomechanical signature. Flat-foot strike, dynamic knee valgus loading, ankle stiffness. Points to specific trainable deficits. Programs that incorporate multiplanar deceleration training, calf/ankle loading work, and perturbation-based drills in defensive contexts are most aligned with these injury mechanics.
