A system and associated method for arthroscopic repair is particularly adaptedin reattaching a ligament and/or tendon to cortical bone of the shoulder. A sutureanchor system includes a suture anchor, preferably, a screw anchor, and an installationtool for installing the suture anchor in tissue. The suture anchor defines a longitudinalaxis and has a longitudinal cannulation for reception and passage of a guide wire.The suture anchor has trailing and leading ends, and an anchor head adjacent thetrailing end thereof. The anchor head includes at least one eyelet for receptionof a suture and an internal bore therein. The installation tool includes a mainbody and a driver head extending from the main body. The main body includes an outersurface having a longitudinal recess therein to accommodate the suture. Thedriver head is correspondingly dimensioned to be received within the internalbore of the anchor head of the suture anchor whereby movement of the installationtool about a longitudinal axis, e.g., rotational movement, thereof causes correspondingmovement, e.g., rotational, of the suture anchor. The installation tool mayalso define a longitudinal cannulation for reception and passage of the guidewire.
