A system and associated method for arthroscopic repair is particularly adapted in reattaching a ligament and/or tendon to cortical bone of the shoulder. A suture anchor system includes a suture anchor, preferably, a screw anchor, and an installation tool for installing the suture anchor in tissue. The suture anchor defines a longitudinal axis 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 the trailing end thereof. The anchor head includes at least one eyelet for reception of a suture and an internal bore therein. The installation tool includes a main body and a driver head extending from the main body. The main body includes an outer surface having a longitudinal recess therein to accommodate the suture. The driver head is correspondingly dimensioned to be received within the internal bore of the anchor head of the suture anchor whereby movement of the installation tool about a longitudinal axis, e.g., rotational movement, thereof causes corresponding movement, e.g., rotational, of the suture anchor. The installation tool may also define a longitudinal cannulation for reception and passage of the guide wire.
