Lower Extremity Alignment is a Risk Factor for Non-Contact Anterior Cruciate Ligament Injuries in Elite Male Wrestlers

This study investigated the potential link between lower extremity alignment and Anterior Cruciate Ligament (ACL) injuries in elite male wrestlers. It was hypothesized that lower extremity alignment could predict ACL injury risk. Sixty male wrestlers, divided into injured (n=30) and non-injured (n=30) groups. Lower extremity alignment indices, including pelvic inclination, hip anteversion, quadriceps angle, knee hyperextension, tibial torsion, plantar arch index, and rear foot angle, were measured. Multiple logistic regression analysis was employed to identify predictor factors for ACL injuries. The results revealed that only the plantar arch index was a statistically significant predictor for non-contact ACL injuries in elite male wrestling athletes (P<0.05). Consequently, the findings suggest that focusing on distal variables of the knee may be crucial when designing ACL injury prevention programs.
