Abstract
A knotless suture anchor for reattachment of tissue to bone features a barbed body having a Y-shaped slot formed distally for capturing a length of suture. The suture is passed through the tissue to be reattached, and a simple knot formed in the suture is captured in the slot on the suture anchor. The anchor is installed with the captured suture into a pre-formed pilot hole to draw the tissue to the bone.
