Abstract:
1. A ligament graft fixation system for fixing ligament graft material within a bone tunnel comprising: an expandable fixation member having opposed bone engaging elements disposed about its periphery, the fixation member having a proximal end, a distal end and an expansion plug receiving opening defined in the proximal end, at least one plug retaining element provided in the expansion plug receiving opening; a graft receiving eyelet disposed proximate the distal end of the expandable fixation element; and a graft location groove provided on the expandable fixation member extending proximally from the graft receiving eyelet; and an expansion plug having a diameter greater than a diameter of the expansion plug receiving opening and having an engaging element matable with the plug retaining element wherein forceable insertion of the expansion plug into the expansion plug receiving opening causes an expansion of the expandable fixation member driving the opposed bone engaging elements apart so as to fix the bone engaging elements in a bone tunnel.
