Method and apparatus for fixation of an ACL graft
First Claim
1. A method of graft fixation for use in a knee reconstruction procedure, comprising:
- forming a femoral tunnel in a femur and a tibial tunnel in a tibia, the femoral tunnel having a first end adjacent to a joint space between the femur and the tibia, and the tibial tunnel having a first end adjacent to the joint space and an opposite second end spaced apart from the joint space;
positioning a first femoral fixation member coupled to a first self-locking adjustable flexible member construct into the femoral tunnel and retaining the first femoral fixation member relative to the femoral tunnel, the first flexible member construct including a first pair of adjustable loops;
tensioning free ends of the first flexible member construct to reduce a size of the first pair of adjustable loops and draw the graft into the femoral tunnel;
passing the graft through the tibial tunnel;
tensioning the graft relative to the femoral and tibial tunnels;
implanting a tibial fixation member relative to the tibial tunnel to fix the tensioned graft to the tibia; and
implanting a second femoral fixation member in the femoral tunnel such that a distal end of the second femoral fixation member is positioned adjacent the first end of the femoral tunnel to fix the graft relative to the first end of the femoral tunnel, wherein implanting the second femoral fixation member in the femoral tunnel includes receiving the second femoral fixation member in the femoral tunnel in an interference fit relationship in the femoral tunnel so that movement of the second femoral fixation member in at least one axial direction in the femoral tunnel is resisted.

Abstract
A system for use in graft fixation in a knee reconstruction procedure can include a first femoral fixation member adapted to be retained relative to a first end of a femoral tunnel and a first self-locking adjustable flexible member construct having a passage portion with a pair of free ends and a pair of self-locking adjustable loops. The first flexible member construct can be interconnected to the first femoral fixation member. A second femoral fixation member can be coupled to the first flexible member construct and can be adapted to be positioned in the femoral tunnel relative to a second end of the femoral tunnel adjacent a joint space between the femur and a tibia. A second self-locking adjustable flexible member construct having a passage portion with a pair of free ends and a pair of self-locking adjustable loops can be interconnected to the second femoral fixation member.
