1. 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 first tunnel comprises 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;
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.

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 anterior cruciate ligament reconstruction, comprising:
-
a first fixation device comprising a plug 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; and a second fixation device 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 (9, 10, 11, 12, 13, 14)

15. 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, the plug comprising; a body extending along a longitudinal axis from a leading end to a trailing end; a first groove and a second groove extending generally parallel to the axis along a first pair of opposite sides of the body; and a pair of indentations extending generally parallel to the axis along a second pair of opposite sides of the body, wherein the second pair of opposite sides is interposed with the first pair of opposite sides and wherein a cross section of the body transverse to the longitudinal axis from the leading end to the trailing end comprises a pair of open crescent-like portions in back-to-back relationship forming a pair of indentations having at least one convex portion; 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; and a second fixation device for implantation proximate a second end of the femoral tunnel, wherein the first fixation device is connected to the second fixation device, and wherein the second fixation device is adapted to secure the first fixation device to the femur. - View Dependent Claims (16, 17, 18, 19, 20)
