<p>This invention is a ligament fixation for a ligament anchor system (10), and a process for its use in an arthroscopic procedure for mounting a ligament graft end in a tunnel formed into a bone. The anchor system includes a footing member (13) for positioning in a bone tunnel, and includes a longitudinal opening (15) formed therethrough, a ligament carrying member (11) that has a forward of proximal portion for fitting through the member longitudinal opening, and includes a coupling (12) for securing it to the footing member. The ligament carrying member further includes a rear or distal portion that incorporates a ligament mounting section having a center longitudinal axis wherefrom at least one, and preferably a pair of spaced apart pointed posts, extend at essentially right angles that include serration or downwardly sloping teeth formed along at least one side of each post, the post or posts for passing through transverse holes formed in an end of a ligament graft, such as a bone end of a bone tendon ligament graft, with the ligament graft bone end urged onto the mounting plate posts axially mounting thereto. The ligament carrying member with axially mounted ligament graft are guided in the bone tunnel and into the footing longitudinal opening, with the ligament carrying member to lock therein. After the ligament graft is placed under tension and the opposite graft end secured, should an adjustment of ligament graft tension be desirable, the footing member is turned appropriately in the bone tunnel.</p> |
