Abstract:
1. An implant for securing and positioning a replacement ligament in a bone tunnel of a receptor bone, said implant comprising: a proximal end, a distal end, and a longitudinal axis, wherein a cross-sectional dimension of said implant at said proximal end is greater than a cross-sectional dimension of said implant at said distal end; said implant defining an opening at said distal end extending completely through said implant in a direction transverse to said longitudinal axis, wherein said opening is defined by a closed perimeter wall formed completely around said opening; said implant including a body portion having a uniform cross-section; and said implant having a multi-angular portion at said proximal end, said multi-angular portion forming a plurality of ridges extending substantially parallel to said longitudinal axis and having a polygonal cross-section about a periphery of the proximal end configured to be inserted within said bone tunnel, wherein a radial dimension of said multi-angular portion at a mid-point between said ridges is the same as a radial dimension of said body portion and a radial dimension of said ridges is greater than the radial dimension of said body portion; wherein said implant is configured to receive a strand in said opening to position said replacement ligament against said implant for securing said replacement ligament in said bone tunnel; and wherein said implant is sized to have a total length extending from said proximal end to said distal end such that said total length is received entirely within said receptor bone.
