DEVICES FOR POSITIONING AND SECURING LIGAMENT GRAFTS

摘要

Devices for positioning and securing ligament grafts are provided. In general, the devices utilize an implant having a particular outer surface profile and a bone tunnel having a complementary profile to provide a form fit between the implant and bone that utilizes friction to position and secure a ligament graft within the bone. Such an implant can be used in conjunction with a variety of ligament grafts, including hamstring ligament grafts. In addition, an "outside in" approach can be utilized with the implant to minimize the risk of damaging adjacent tissue during an operation and provide enhanced surgeon control. The devices can be utilized in connection with repairing or replacing ligaments in a variety of joints, but can in some embodiments have particular utility in cruciate ligament reconstruction procedures.
