Anterior cruciate ligament rupture in skiing

A new mechanism of injury

Department of Orthopaedic Surgery, University of British Columbia, Vancouver, British Columbia, Canada

Between January 1981 and March 1985, the author examined and treated 13 skiers who suffered ACL rupture of their knees in a characteristic but previously undescribed fashion. Injury is caused by a combination of passive and active loads applied to the ACL. Ultimate failure of the ACL is produced by violent quadriceps contraction to recover from an out of control sitting- back posture or to gain control after landing a jump. The injury is exclusive to expert skiers and there is no binding release. Combined loading of the ACL in skiing is exceedingly dangerous.
