Abstract:
1. A method for securing a graft ligament in a bone tunnel having an end opening in a bone surface, a free end of the graft ligament extending out of the bone tunnel end opening, the method comprising the steps of: providing a tubular fixation screw for insertion into the bone tunnel adjacent the graft ligament for impinging upon the graft ligament and a wall of the bone tunnel to fix the graft ligament to the wall in the bone tunnel, the screw comprising: pulling the graft ligament taut; inserting the fixation screw into the bone tunnel and advancing the screw therein to threadedly engage the graft ligament and the wall of the bone tunnel to fix the graft ligament in the bone tunnel; and turning the screw until the shank proximal end surface thereof is substantially flush with the surrounding bone surface, and the apertures extending through the shank sidewalls are disposed to receive migration of material from the bone tunnel wall to lock the screw and the graft ligament in the bone tunnel.
