This study was performed to examine tibial rotation and valgus movement at the knee during dynamic sport-specific movements, a jump stop and a side cut maneuver associated with anterior cruciate ligament (ACL) injury. We aimed to assess whether six male and eight female skilled soccer athletes perform these maneuvers with different magnitudes of valgus movement and tibial rotation at the knee. Nine trials of each maneuver were analyzed for each subject. There was a significant difference between males and females for valgus angle at contact, maximum valgus angle, and maximum external rotation (p<0.05). There was no difference for any dependant variable between jump stop and side cut maneuver, and Sex * Maneuver no interaction. Though there is certainly more than one reason for greater number of ACL injuries in females, not finding a difference in valgus movement between the sexes may indicate that tibial rotation might play a greater role than valgus movement alone.
