Differences in movement patterns related to anterior cruciate ligament injury risk in elite judokas according to sex: A cross-sectional clinical approach study

The anterior cruciate ligament (ACL) injury stands as a significant concern in judo, necessitating preventive measures. The primary injury mechanism involves knee collapse in valgus, often linked to deficiencies in core strength, neuromuscular control, external rotators, hip abductors, and limitations in ankle and hip mobility. Sex-wise, the injury is more prevalent in women across various sports. Therefore, in the present study we observed this possible intersexual disparity in the difference of movement patterns among elite judokas according to their sex, in order to identify those athletes with a higher risk of ACL injury. Notably, there were no discernible differences between sexes in the single leg squat test. Both men and women exhibited compromised neuromuscular control in the non-dominant leg. While ankle dorsiflexion and hip external rotation showed no gender disparities, differences in internal rotation were noted. This particular movement restriction may elevate the risk of ACL injury.
