Suture anchor

A knotless suture anchor system comprising:

• an anchor body having an exterior surface, a proximal end, a distal end, a longitudinal axis extending between the proximal and distal ends, an interior longitudinal passageway extending at least partway from the proximal end toward the distal end, a proximal opening communicating with the longitudinal passageway nearer the proximal end, and a first distal opening communicating with the longitudinal passageway nearer the distal end;
• and
• a tensioner connected to the anchor body and operable to engage the proximal end, secure a suture extending from the anchor body, and apply tension to the suture;
• and
• a proximal member connected to the proximal end of the anchor body by a frangible connection.

• a proximal member joined to the anchor body, the proximal member having external threads at a proximal end of the proximal member;
• a set screw insertable distally into the longitudinal passageway to releasably secure a first portion of a suture within the longitudinal passageway by compressing the first portion of the suture between external knuckle threads of the set screw and internal helical threads at the proximal end of the anchor body;
• a frangible connection that joins the proximal member to the anchor body;
• and
• a tensioner connected to an inserter operable to engage the proximal member, the tensioner operable to secure a second portion of the suture contiguous to the first portion and extending from the anchor body, the tensioner also operable to apply tension to the second portion of the suture.
