ABSTRACT:
A disposable, double-diameter knot pusher for use in arthroscopic surgery. The knot pusher is formed of two telescoped tubes, specifically, an inner, smaller diameter pusher tube slidably disposed within an outer, larger diameter pusher tube. The first knot is thrown around the suture post limb, and is pushed along the post limb with the inner tube. The inner tube holds the first knot in place, while the second knot is thrown around the inner tube and pushed into place with the outer tube. A suture passer is used to draw a post section of suture through the inner tube to begin the knot-tying process.
