Abstract
Systems and methods for ligament reconstruction provides an implant configured to position ligaments in the anatomic positions to thereby to restore the native anatomy and function of the reconstructed area. The implant includes a sheath, a first ledge, a second ledge, a first anchor and a second anchor. The sheath has an exterior surface and an interior surface, wherein the interior surface of the sheath forms a lumen configured to receive a sheath expander. The first ledge and the second are configured to separate the ligaments and acts as an anchor for the sheath in the bone tunnel. The first anchor and the second anchor are configured to engage the ligaments and be expandable outwards away from the lumen to provide fixation in a bone tunnel. When the implant receives the sheath expander, the ligaments can be separated, positioned, and secured in the bone tunnel.
