Abstract
A system for fixing soft tissue within a bone tunnel includes a first fixation member that is adapted for insertion upon a piece of soft tissue positioned within a bone tunnel, with a portion of the soft tissue emerging therefrom. A second fixation member is adapted to engage the first fixation member at its proximal end and is restrainable against disengagement therewith. The proximal end has an element for engaging the soft tissue. In a particular embodiment the first fixation member includes a screw having a bore extending from the proximal end and the second fixation member has a distal post portion adapted for mating with the bore and driving the screw rotationally thereby. The second fixation member may include a tack member and a barbed washer that is rotatable about the post and retainable by a head portion on the tack member. The barbs on the washer are for engaging and restraining a movement of the soft tissue outside the bone tunnel. Alternatively, the second fixation member may include a tack-type element that has a barbed head. In another embodiment a cannula capable of restraining the washer against rotation is used to guide the screw into the bone tunnel.
