ANTERIOR CRUCIATE LIGAMENT TEAR IN AN ATHLETE: DOES INCREASED HEEL LOADING CONTRIBUTE TO ACL RUPTURE?

Rupture to the anterior cruciate ligament is a common athletic injury in American football. The lower extremity biomechanics related to increased ACL injury risk are not completely understood. However, foot landing has been purported to be a significant contributing factor to the ACL injury mechanism. In this case report, information is presented on an athlete previously tested for in-shoe loading patterns on artificial turf and subsequently went on to non-contact ACL rupture on the same surface. This case report describes the specific findings in a study participant who suffered an ACL rupture after testing and suggests that flatfoot tendency in running and cutting maneuvers might lead to an increased risk of ACL injury.
