A pound-in suture anchor that self-twists upon insertion into a drilled pilot hole. The suture anchor is provided with threads that allow the anchor to be inserted within a pilot hole without tapping the pilot hole and without turning (or twisting) the driver handle. The suture anchor of the present invention is designed to twist by itself as it is advanced into the pre-drilled pilot hole by malleting the driver handle. The suture anchor has an eyelet for receiving one or more suture strands for securing soft tissue to bone.
