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.

[ What is claimed is:] [1.] A system for fixing soft tissue within a bone tunnel comprising:a first fixation member having a proximal end and a distal end and adapted for insertion against a first portion of soft tissue positioned within a bone tunnel, a second portion of the soft tissue emerging from the bone tunnel; anda second fixation member adapted to engage the first fixation member at the proximal end thereof, the second fixation member having means for restraining disengagement therewith and a proximal end having means for engaging the soft tissue second portion, wherein the second fixation member when engaged with the first fixation member is decoupled in at least one degree of freedom therefrom.
