This meta-analysis pooled 33 studies to generate exposure-weighted ACL tear incidence rates. It asks how tear rates truly vary by gender, by sport, and with injury-reduction training. The goal was to replace inconsistent literature claims with reliable pooled estimates.
When you counsel a young female soccer or basketball player, quote a 3-fold gender risk, not the inflated 6- to 9-fold figure that circulates informally. This paper's exposure-weighting is its core strength. Rates from massive NCAA datasets (millions of exposures) are reliable, while eye-catching numbers from wrestling, indoor soccer, and volleyball rest on tiny samples and should be trusted less.
The training data carries a real clinical caveat: neuromuscular prevention programs demonstrably reduce ACL tears in soccer but showed no benefit in basketball in this pooled analysis. Do not assume a soccer-validated program transfers to every court sport. The Alpine skiing finding reframes prevention: coaching novice skiers toward proficiency lowered risk more than any formal program did.
Remember the limitations. This is Level IV evidence with selection bias, format-conversion assumptions, and mostly retrospective source studies.
