Endosteal fixation of a ligament graft with an interference fixation device installed in a retrograde manner is disclosed. An interference screw is installed at the top of the tibial tunnel, through the tibial plateau, in a procedure for ACL reconstruction. The interference screw is fitted with a length of suture for pulling the screw onto a driver placed through the tibial tunnel. The suture is secured to the screw using a knot, an adhesive, insert molding, and equivalents. The suture extends beyond the leading tip of the screw a sufficient length to allow the screw to be passed into the joint by pulling on the suture exiting the tibial tunnel. A driver fits into a drive opening in the leading front end of the screw. Turning the driver advances the screw in a retrograde manner into the tunnel. Accordingly, interference fixation of the graft near the tibial plateau is provided, thereby eliminating graft abrasion at the tibial plateau tunnel opening.
