Abstract

Sutures with pre-tied knots for use in percutaneous surgical procedures. Described herein are pre-tied sutures and methods of using them that may be used with a suture passer for percutaneously suturing tissue, including percutaneously passing and securing a loop of suture around a tear in a meniscus tissue of the knee. A suture with a pre-tied knot may include a length of suture and a knot body on the length of suture, and a leader snare tied to the length of suture by the knot body. The leader snare typically has an opening loop (bight or snare) through which an end of the suture may be passed. The tail of the leader snare may be pulled to remove the leader snare for the knot body and draw the end of the suture through the knot body to close the knot, which can then be tightened to secure the tissue.
