ABSTRACT:
A suture anchor is disclosed which comprises a frusto-conical device having first and second axial ends, and a side surface extending therebetween. The first axial end has a larger diameter than the second axial end. The first axial end includes an internally threaded bore by which a driver is removably connected to the anchor. A passage extends through the suture anchor from the second axial end and to the side surface. Tissue is attached to a bone by first passing a length of suture material through the tissue. The suture ends are delivered to the anchor and are passed through the passage in a direction from the axial end to the side surface. The user then grasps the suture ends and inserts the anchor, by means of the driver, into a previously prepared bore in the bone. The anchor is wedged into the bore so that the suture is captured between the bone and the side surface of the anchor.
