A suture anchor system including an anchor, a plug and an inserter. The anchor inserter includes a tubular outer shaft having a cannulation dimensioned to receive an inner shaft. The distal end of the outer shaft cannulation is threaded for engagement with the plug. The anchor includes a longitudinal cannulation formed within the anchor body, including a smooth-sided proximal portion and a threaded distal portion. An eyelet, dimensioned to receive a suture therein, extends transverse to the longitudinal axis of the anchor and intersects the threaded distal portion of the cannulation. The plug is a generally elongated, tubular threaded rod comprising a cannulation adapted to receive a distal end of the inner inserter shaft.
