Patent ID: 7338492

Claim:
A graft retaining system for retaining a graft in a bone tunnel comprising: a graft block having a proximal end and a distal end, the graft block being sized to slidingly fit within the bone tunnel, the graft block including a distally-facing support surface at the distal end for supporting an intermediate connector, a pair of transverse throughbores being formed through the support surface; an intermediate connector connecting a predetermined portion of the graft and a predetermined portion of the graft block, the intermediate connector formed of an elongated member forming a loop supported by the support surface of the graft block, the elongated member having a first end and a second end, at least one of the first and second ends being threaded in one direction through at least one of said transverse throughbores; means for preventing said threaded end from passing back through said at least one transverse throughbore; and means on said graft block for receiving a separate transverse member to attach the graft block at a predetermined point along the length of the tunnel, the transverse member being situated transverse to the axis of the bone tunnel and through the loop created by said intermediate connector, said support surface comprising a convex surface bounded on at least two sides by projecting side walls to retain the intermediate connector on the convex surface, wherein said intermediate connector is a suture-like material and wherein said pair of transverse throughbores are formed through the support surface generally parallel to the side-walls from a first portion of the convex surface to a second portion of the convex surface, each of the throughbores being countersunk at at least one end such that the ends of the intermediate connector may be secured to the graft block by being threaded through respective throughbores knotted and pulled back into the countersunk ends of the throughbores.
