Double bundle ACL repair
First Claim
1. A system adapted to secure a graft in a bone tunnel, wherein the graft comprises a plurality of separate bundles between opposite first and second parts of the graft, the system comprising:
- an implant, wherein the implant comprises a length extending along a longitudinal axis between opposite first and second ends of the implant, a hole in the first end of the implant, a groove across the second end of the implant, an aperture extending through the implant, wherein the hole is aligned with the length, wherein the aperture is transverse to the length, a first groove and a second groove extending generally parallel to the axis along a first pair of opposite sides of the implant, a pair of indentations extending generally parallel to the axis along a second pair of opposite sides of the implant, wherein the second pair of opposite sides is interposed with the first pair of opposite sides, and wherein a view of the implant from the trailing end comprises a pair of open crescent-like portions in back-to-back relationship forming the pair of indentations having at least one convex portion;
a button; and
a loop, wherein the loop connects the implant to the button.

Abstract
A system for single tunnel, double bundle anterior cruciate ligament reconstruction includes implant constructs and instruments. The implant constructs provide a combination of cortical fixation and bone tunnel aperture fixation. The implant constructs separate a graft into distinct bundles. The instruments are used to prepare shaped bone tunnels to receive the implant constructs and graft bundles. Methods for reconstructing the antero-medial and postero-lateral bundles of the anterior cruciate ligament may rely on single femoral and tibial tunnels and a single strand of graft.

8. A system for securing a graft in a bone tunnel, wherein the graft comprises a plurality of separate bundles between opposite first and second parts of the graft, the system comprising:
-
first fixation means for suspending the first part of the graft in the bone tunnel; first body means for separating the graft bundles proximate a first end of the bone tunnel, and for urging the graft bundles against a side wall of the bone tunnel at the first end of the bone tunnel, wherein the first body means comprises a first groove and a second groove extending generally parallel to an axis along a first pair of opposite sides of the first body means, a pair of indentations extending generally parallel to the axis along a second pair of opposite sides of the first body means, wherein the second pair of opposite sides is interposed with the first pair of opposite sides, and wherein a view of the first body means from the trailing end comprises a pair of open crescent-like portions in back-to-back relationship forming the pair of indentations having at least one convex portion; and first connection means for securing the fixation means to the body means. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)

16. A system for anterior cruciate ligament reconstruction, comprising:
-
a first apparatus for securing a first end of a soft tissue graft to a first bone of a joint, the first apparatus comprising; body means for separating the graft into a plurality of bundles and for urging the bundles against a side wall of a first bone tunnel at a first end of the first tunnel, wherein the first tunnel is formed in the first bone, wherein the first end of the first tunnel is proximate an articular surface of the first bone, wherein the body means is adapted to be inserted in the first tunnel comprising a noncircular cross section projected along a longitudinal axis from the first end of the first tunnel to a second end of the first tunnel, wherein the second end of the first tunnel is remote from the articular surface of the first bone, wherein the body means comprises a first groove and a second groove extending generally parallel to an axis along a first pair of opposite sides of the body means, a pair of indentations extending generally parallel to the axis along a second pair of opposite sides of the body means, wherein the second pair of opposite sides is interposed with the first pair of opposite sides, and wherein a view of the body means from the trailing end comprises a pair of open crescent-like portions in back-to-back relationship forming the pair of indentations having at least one convex portion; fixation means separate from the body means for securing the first end of the graft to the first bone; and connection means for securing the body means to the fixation means. - View Dependent Claims (17, 18, 19, 20, 21, 22)

23. A system for anterior cruciate ligament reconstruction, comprising:
-
a first fixation device comprising a plug adapted for insertion into a first end of a noncircular bone tunnel in a femur, wherein the first end of the femoral tunnel intersects a distal articular condyle of the femur, wherein, when the plug is operatively positioned in the femoral tunnel, a plurality of spaced-apart chambers are formed between the plug and a side wall of the femoral tunnel, wherein the first fixation device comprises a first groove and a second groove extending generally parallel to an axis along a first pair of opposite sides of the first fixation device, a pair of indentations extending generally parallel to the axis along a second pair of opposite sides of the first fixation device, wherein the second pair of opposite sides is interposed with the first pair of opposite sides, and wherein a view of the first fixation device from the trailing end comprises a pair of open crescent-like portions in back-to-back relationship forming the pair of indentations having at least one convex portion; and a second fixation device adapted for implantation proximate a second end of the femoral tunnel, wherein the first fixation device is connected to the second fixation device, wherein the second fixation device secures the first fixation device to the femur. - View Dependent Claims (24, 25, 26, 27, 28)
