Abstract
Abstract A tissue graft is secured within a bone passage by providing a graft fixation member sized to pass through the bone passage, attaching a suture having a pair of free ends to the tissue graft and tying the suture to the fixation member so that the free ends pass through an opening in the fixation device from a first side to a second side and a length of the suture extends between the tissue graft and fixation member. The length of the suture between the tissue graft and the fixation member is adjusted by pulling at least one of the free ends, and the suture is secured to the fixation member to maintain the adjusted length.
