<p>A graft clamp (10) for securing a tissue graft (16) located within a tunnel (12) in bone includes a first member (22) having a first clamping face (37), and a second member (20) having a second clamping face (52). The first and second members (20) are sized for positioning at an opening of the tunnel (12) such that the first and second clamping faces are positioned substantially transversely to a bone surface defining the tunnel opening to secure the tissue graft (16) therebetween. The clamping faces have ridges (40, 50). The first member (22) includes a spike (39) for insertion into the bone, and a collar for insertion into the opening of the tunnel. An attaching element, for example, a screw (24), attaches the second member (20) to the first member (22). The clamping faces are located exterior to the tunnel with the attaching element extending into the tunnel. The position of the first member and the second member at the tunnel opening is maintained at least partially by tension applied to the tissue graft.</p> |
