Related people

An avulsion fracture of the anterolateral margin of the lateral tibial plateau, associated with anterior cruciate ligament (ACL) tears. The fracture is considered pathogonomic for ACL tears. The mechanism of injury is internal rotation and various stresses, which causes abnormal tension on the central portion of the lateral capsular ligament.
