摘要:
A simple, threaded suture anchor is pre-loaded with suture in a configuration that allows a surgeon to compress tissue against the bone without tying a knot. The knot-tying step is replaced by a simple suture looping step which requires less time and is not prone to errors in knot tying technique. The suture anchor is a screw-in style anchor body. The suture is loaded into the anchor in a configuration that allows it to create a loop on top of the tissue after it has been passed through the tissue from bottom to top. The suture limbs are then loaded into a knotless anchor which is implanted off the lateral edge of the tissue. Tensioning of the suture limbs in the knotless anchor tightens the loop on top of the tissue, providing a fulcrum point of fixation over the pre-loaded suture anchor without the otherwise need for requisite knot tying.
