A system for fixing soft tissue within a bone tunnel includes a first fixation member that is adapted for insertion against a piece of soft tissue positioned within a bone tunnel, with a portion of the soft tissue emerging therefrom. The first fixation member has a proximal end and a distal end. A second fixation member can engage the first fixation member at its proximal end and also can prevent the first fixation member's proximal end from passing into the bone tunnel. The proximal end has barbs for engaging the soft tissue's second portion. Another element is engageable with the second fixation member for extracting it from engagement with the soft tissue's second portion.
