A fixation screw, graft ligament anchor assembly, and method for fastening a graft ligament in a bone tunnel. The screw comprises an elongated shank having a distal end and a proximal end, and a central axis extending from the distal end to the proximal end. Screw threads are disposed on the shank and extend from the distal end to the proximal end. The proximal end defines an end plane disposed transversely to the axis and at an angle thereto other than a normal angle.

Fixation screw, graft ligament anchor assembly, and method for securing a graft ligament in a bone tunnel

An endosteal anchoring device for urging a ligament graft against a bone surface comprising an anchoring body, a means for resisting slippage of the anchoring body into the periphery of a bone tunnel under ligament tension, a means for avoiding puncturing, piercing or tearing of cross-fibers of the ligament graft and a means for urging the ligament graft flush against the inner surface of the bone tunnel for accelerated healing.
