Abstract: A locking suture construct having suture material with a first end and a second end, each attached to a first body in a slidable manner, a constricting member formed in the second end of the suture material, and a bight in the suture material between the first end and the second end. The bight can be pulled through the constricting member around a second body to create a locking loop. The first end and the second end are passed through the locking loop. Pulling the first end increases a perimeter of the locking loop and moves the constricting member toward the second body. When the constricting member reaches the second body, pulling the first end reduces the perimeter of the locking loop and moves/rotates the constricting member around the second body toward the first body to hold the first body in relative position to the second body.
