A system and method for attaching tissue to bone are provided. In one embodiment, a system for attaching tissue to bone includes a suture, suture anchor, inserter tool, drill, and drill guide having an outer guide (22) and an inner guide (24). A method for attaching tissue to bone includes attaching a suture to tissue, nesting the suture in a notch on the distal end of the outer guide, passing the suture through a lumen formed in the outer guide, and inserting an inner guide in a lumen formed in the outer guide. The drill guide protects the suture from rotational movement of the drill and allows a user to maintain alignment between the drill guide and the drilled hole. As a result, a suture anchor can be more easily positioned within the drilled hole.
