Tendon Suture Anchors
Evolution of Tendon Suture Anchors
The suture anchor is another method of attaching tendon to bone. Using a small drill, two anchors are inserted into the thickest portion of the bone. One end of the suture is attached to the two suture anchors. The suture anchors serve to anchor the suture to the bone. The other end of the suture is again attached to the end of the tendon. The tendon is drawn up against the bone without the need to drill a hole or pass suture through to the other side of the bone.
This method is useful when suture cannot be passed through to the far side of the bone or when such a “pass through” would cause damage on the far side. Suture anchors are also easier to use during laparoscopic surgery (surgery using small holes, long instruments, and a camera). Anchor design has evolved from screws and barbs to soft anchors composed of only suture material.
The Juggerknot soft anchor system, developed in 2009, consists of a thicker polyester sleeve attached to a braided suture with suture needles. A small drill is used to prepare several holes to place the anchor. The Juggerknot inserter advances the soft, thickened sleeve anchor into the drilled hole. The sutures are removed from the inserter, at which point the soft anchor is firmly locked in the hole. The suture and needles are used to suture the tendon end to the bony anchor.
The Juggerknot soft anchor system is available in various sizes and can be used for tendon repairs on the shoulder, elbow, wrist, hand, hip, knee, foot and ankle. The Juggerknot suture anchor has the benefit of a smaller hole and less removed bone without sacrificing strength of attachment. They also do not require any knots for attachment to the anchor, thus eliminating a common point of failure.
