A suture anchor system, comprising: an inserter comprising: an elongated, cannulated outer shaft extending between a proximal end and a distal end; and an elongated inner shaft extending between a proximal end and a distal end, wherein the inner shaft is dimensioned for receipt within the outer shaft, and wherein the inner shaft is axially moveable independent of the outer shaft; an anchor, comprising: an elongated anchor body extending longitudinally between a proximal end and a distal end; a closed eyelet, extending transversely through a longitudinal axis of the anchor, and dimensioned to receive one or more sutures; and a cannulation formed within the anchor body and intersecting the eyelet, the cannulation including: a proximal cannulation portion extending distally from the proximal end of the anchor body to a first longitudinal position proximal to the eyelet; and a threaded distal cannulation portion extending distally from the first longitudinal position to a second longitudinal position distal to the eyelet; and a threaded, tubular plug comprising a longitudinal cannula extending between a proximal end and a distal end; the inner shaft of the inserter engageable with the cannula of the plug to move the plug distally with respect to the anchor from a first axial position to a second axial position; wherein, in the second axial position, the plug engages the anchor body but not the outer shaft of the inserter and the distal terminus of the plug abuts a distal terminus of the anchor body cannulation, characterised in that a distal end of the outer shaft is threaded and wherein in the first axial position, the plug engages via a thread both the anchor body and the outer shaft of the inserter and a distal terminus of the plug is proximal to the eyelet. an inserter comprising: an elongated, cannulated outer shaft extending between a proximal end and a distal end; and an elongated inner shaft extending between a proximal end and a distal end, wherein the inner shaft is dimensioned for receipt within the outer shaft, and wherein the inner shaft is axially moveable independent of the outer shaft; an elongated, cannulated outer shaft extending between a proximal end and a distal end; and an elongated inner shaft extending between a proximal end and a distal end, wherein the inner shaft is dimensioned for receipt within the outer shaft, and wherein the inner shaft is axially moveable independent of the outer shaft; an anchor, comprising: an elongated anchor body extending longitudinally between a proximal end and a distal end; a closed eyelet, extending transversely through a longitudinal axis of the anchor, and dimensioned to receive one or more sutures; and a cannulation formed within the anchor body and intersecting the eyelet, the cannulation including: a proximal cannulation portion extending distally from the proximal end of the anchor body to a first longitudinal position proximal to the eyelet; and a threaded distal cannulation portion extending distally from the first longitudinal position to a second longitudinal position distal to the eyelet; and an elongated anchor body extending longitudinally between a proximal end and a distal end; a closed eyelet, extending transversely through a longitudinal axis of the anchor, and dimensioned to receive one or more sutures; and a cannulation formed within the anchor body and intersecting the eyelet, the cannulation including: a proximal cannulation portion extending distally from the proximal end of the anchor body to a first longitudinal position proximal to the eyelet; and a threaded distal cannulation portion extending distally from the first longitudinal position to a second longitudinal position distal to the eyelet; and a proximal cannulation portion extending distally from the proximal end of the anchor body to a first longitudinal position proximal to the eyelet; and a threaded distal cannulation portion extending distally from the first longitudinal position to a second longitudinal position distal to the eyelet; and a threaded, tubular plug comprising a longitudinal cannula extending between a proximal end and a distal end; the inner shaft of the inserter engageable with the cannula of the plug to move the plug distally with respect to the anchor from a first axial position to a second axial position; wherein, in the second axial position, the plug engages the anchor body but not the outer shaft of the inserter and the distal terminus of the plug abuts a distal terminus of the anchor body cannulation, characterised in that a distal end of the outer shaft is threaded and wherein in the first axial position, the plug engages via a thread both the anchor body and the outer shaft of the inserter and a distal terminus of the plug is proximal to the eyelet.
