Abstract

A suture anchor apparatus for anchoring a suture in a bone. The apparatus includes an anchor with an elongate tip, a threaded portion and a suture securing structure coupled to the threaded portion. The tip includes a leading end, a trailing end and a longitudinal axis extending therebetween. The tip further has a length measured from the leading end to the trailing end, a width measured at the trailing end and an aspect ratio equal to the length divided by the width. The threaded portion is coupled to the trailing end of the tip and extends back therefrom and includes a generally cylindrical root with a screw thread formed thereon. The root has an elongate axis collinear with the longitudinal axis of the tip and the threads having an outside diameter substantially greater than the width of the tip. The aspect ratio and length of the tip are configured to make the anchor stable with only the tip inserted into the bone.
