Claims31
A graft retaining system for retaining a graft in a bone tunnel in a bone, the system comprising:
- encircling means for at least partially encircling a portion of the graft, the encircling means positionable adjacent the bone tunnel, the encircling means being movable from a first position in which the graft passes generally straight through the encircling means to a second position in which the graft is forced into a tortuous path through the encircling means such that the graft is gripped by the encircling means;
- and
- securing means for securing the graft and encircling means relative to the bone tunnel with the encircling means in the second position.
A graft retaining system for retaining a graft in a bone tunnel, the system comprising:
- a first member for gripping the graft, the first member including a portion for at least partially encircling the graft to grip the graft in belt buckle fashion when the first member is rotated relative to the graft;
- and
- a second member for securing the first member and the graft in the tunnel.
A graft retaining system for retaining a graft in a bone tunnel formed in a bone, the system comprising:
- a ring including a cylindrical side wall, the cylindrical wall having an inner surface defining a lumen sized for receiving the graft and an outer surface sized to fit within the bone tunnel, the lumen having a lumen axis;
- a bone engaging prong extending radially outwardly from the ring;
- a fixation tab extending radially outwardly from the ring, opposite the prong, for engaging an interference screw;
- and
- an interference screw engageable with the fixation tab to secure the ring and graft relative to the tunnel.
