Patent ID: 8048158

Claim:
A graft ligament anchor for fixing a graft ligament within a bone tunnel having a circumferential wall and an opening, comprising: a graft ligament fixing element for disposition within the bone tunnel, the graft ligament fixing element having a resiliently deformable side wall configured to contact a graft ligament portion when the graft ligament is placed in the bone tunnel; a graft ligament, the graft ligament being in contact with the side wall; and a locking element configured for placement within the bone tunnel and to engage the graft ligament fixing element, the locking element being separated from the graft ligament by the graft ligament fixing element; wherein the side wall of the graft ligament fixing element has a concavity extending longitudinally and configured to nest the graft ligament when the graft ligament is placed in the bone tunnel; wherein the locking element and graft ligament fixing element are further configured so that movement of the locking element causes a change in shape of the resiliently deformable side wall to thereby urge the side wall of the graft ligament fixing element, and hence the graft ligament, toward the circumferential wall of the bone tunnel so as to secure the graft ligament to the circumferential wall.
