Abstract

Knots and methods of forming knots made of flexible material for use in a surgical environment are described. The knots include one or more ways to unlock at least a portion of the knot.

Claims (15)

1. A method of connecting soft tissue to a bone, comprising:

inserting at least one suture anchor into the bone, the suture anchor having a suture attached thereto, the suture comprising a strand of flexible material with two free ends defining a distal end, the strand of flexible material forming a slip knot and an active loop proximal the slip knot;

passing one of the free ends of the strand through the soft tissue;

threading the free end of the strand through the slip knot;

forming a half hitch knot;

applying tension to the free ends of the strand;

applying a force to the strand so as to cause the half stitch knot to loosen; and

re-applying tension to the free ends of the strand.

2. The method of claim 1 , wherein the strand is a first strand, and wherein the step of applying the force to the first strand comprises applying tension to a second strand of flexible material positioned about the first strand between the slip knot and the half hitch knot.

3. The method of claim 2 , wherein the step of applying the force to the first strand comprises applying tension to a third strand of flexible material positioned about a second portion of the first strand between the slip knot and the half hitch knot.

4. The method of claim 1 , wherein the strand is a first strand, and wherein the step of applying the force to the first strand comprises applying tension to a second strand of flexible material through which a first portion of the first strand is stitched between the slip knot and the half hitch knot.

5. The method of claim 4 , wherein the step of applying the force to the first strand comprises applying tension to a third strand of flexible material through which a second portion of the first strand is stitched between the slip knot and the half hitch knot.

6. The method of claim 1 , wherein the half hitch knot includes a distal loop and a proximal loop, wherein the strand is a first strand, and wherein the step of applying the force to the first strand comprises applying tension to a second strand of flexible material positioned about the distal loop of the half hitch knot.

7. The method of claim 6 , further comprising connecting the second strand to a knot pusher.

8. The method of claim 7 , wherein the knot pusher has a tubular body and a pusher head extending from a distal end of the tubular body, wherein the step of connecting the second strand to the knot pusher comprises positioning the second strand in a groove of the pusher head and detachably connecting at least one end of the strand to the tubular body.
