Abstract: The invention is directed toward a sterile bone-tendon-bone assembly with two allograft bone blocks constructed with a cancellous portion and a cortical end portion. Each bone block has an outer curved surface with two opposing longitudinal arcuate grooves cut into the exterior surface which will allow a tendon replacement member to be wrapped around the bone block. The second bone block being in reversed orientation to the first bone block.

Abstract: A method of inserting a guide pin into tissue including inserting into the tissue a device having a cannula disposed longitudinally therein, a shank, and a tip. A guide pin movably disposed in the cannula and having a shank end proximal to the shank of the drill bit and a tip proximal to the tip of the drill bit. A retaining means associated with at least one of the drill bit and the guide pin for permitting the releasable retention of the guide pin in the cannula by means of adjustable force exerted on the guide pin by the drill bit.

Abstract: A bone block drill guide and a method for preparing a bone plug and tendon graft in which the bone block drill guide is used in drilling a hole through the bone plug. A harvested bone plug and tendon graft is inserted into a trough in a bone block drill guide. A drill bit is inserted through a hole in a drill guide member to accurately drill a hole in the bone plug supported in the trough below. The bone block drill guide may have a plurality of troughs of different widths. A drill guide member has a hole therethrough for guiding a drill bit. The drill guide member is aligned with a trough so that the hole in the guide member is aligned with the hole in the bottom surface of the trough.
