Knotless suture anchor with unthreaded nose

A method for affixing tissue to bone comprising the steps of:

• passing a length of suture through the tissue;
• passing the length of suture through a suture anchor which comprise a tubular body having an axial bore therethrough, one or more purchase enhancements on an exterior surface of the body adapted to enhance purchase of the body within a bone hole, a lateral port through the body from the exterior surface into the axial bore and a distal nose, the suture passing in order distally down along the exterior surface over the one or more purchase enhancements, over the distal nose up into the bore, proximally up through the axial bore out through the lateral port and proximally along the exterior surface over the one or more purchase enhancements;
• embedding the remainder of the suture anchor into the bone adjacent to the tissue and trapping the suture between the suture anchor body and the bone;
• and
• wherein upon the occurrence of a failure, the suture slips with respect to the anchor.
