A suture anchor includes a threaded anchor body having a bore for receiving a driver, and at least two distal passageways extending from the bore to corresponding apertures at the distal end of the suture anchor. The apertures are provided as pairs with a corresponding groove formed between the apertures of the pair. Suture strands can be inserted into the suture anchor through the apertures, the distal portion of the sutures seated in the grooves between the apertures being protected from abrasion during installation of the suture anchor.
