ABSTRACT:
A method of securing a tendon graft in a ligament tunnel is described. The tendon graft is used to replace a ligament and has a length of tendon section with bone grafts attached to the tendon at each end. The method includes the step of providing an interference fixation screws made of material that is soft compared to bone. The fixation screws are cooled to a temperature to make them sufficiently rigid to track in a straight line when they are tightened in the ligament tunnel. Each bone graft is then secured in place in the ligament tunnel by inserting a fixation screw between each bone graft and the bone surrounding the ligament tunnel and tightening it therebetween. After each fixation screw is tightened, it has a portion extending beyond a respective entrance to the ligament tunnel which is then trimmed.
