Posterior cruciate ligament tears in wrestlers.

Two cases of isolated injury to the posterior cruciate ligament of the knee are presented. These injuries both occurred in elite wrestlers, members of the Canadian Pan American Team. The mechanism of injury was identical in both cases--the ligament rupture being a result of forced flexion with combined internal rotation of the tibia on femur. A review of the literature is added with a suggestion for conservative treatment as the initial and perhaps definitive management for this problem.
