Abstract

The present invention provides a method of performing posterior cruciate ligament replacement. Specifically, a graft tissue is harvested from a patient and single tunnels are prepared in each of the tibia and the femur of the patient. The graft is secured in the femoral tunnel and separated into a posterior cruciate medial bundle and a posterior lateral bundle. The bundles are inserted through the tibial tunnel. During insertion the posterior lateral bundle is positioned in a posterior lateral position in the tibial tunnel while the posterior cruciate medial bundle is positioned in a posterior cruciate medial position in the tibial tunnel. The posterior cruciate medial bundle is then tensioned while the patient's knee is in approximately 90 degrees of flexion, and the posterior lateral bundle is tensioned while the patient's knee is approximately in full extension. Each of the bundles is then secured in the tibial tunnel.
