An anchoring system (11) including a suture anchor (10) and an implant delivery device (22) is disclosed. The suture anchor (10) includes an anchor body (12) and a distal member (14) that is rotatable relative to the anchor body (12) about a longitudinal suture anchor axis. The distal member (14) has an aperture (15) that traverses the distal member (14) and includes a slot (56) and an eyelet (16), the eyelet (16) being sized to permit a suture (20) to traverse the distal member (14) through the eyelet (16). The implant delivery device (22) includes a handle portion (28), a drive shaft portion (6) including a cannulated outer shaft (24), and a suture pulley shaft (8) including an inner shaft (26). The cannulated outer shaft (24) is configured to engage a proximal end of the anchor body (12) for driving the suture anchor (10) into a bore. The inner shaft (26) is slidably received in the cannulated outer shaft (24) to maintain the position and tension of the sutures (20) during insertion.
