Press Release Summary:
KINSA RC 5.5 Suture Anchor encases sliding, self-locking knot that permits surgeon to perform secure repair procedure without tying knots on top of tissue. Minimally invasive solution enables low-profile torn tissue reattachment without interfering with joint motion. Suited for double-row fixation, anchor is tapped into bone surface and seated with final twist. Product measures Â½ in. long, is made from implantable PEEK-OPTIMAÂ® polymer, and will not show up on X-rays or distort MRIs.

Smith & Nephew Endoscopy's KINSA® RC Suture Anchor Designed for Secure Repair of Rotator Cuff Injuries
Encased self-locking sliding knot enables surgeons to control tension, avoid tissue damage
ANDOVER, Mass., Sept. 26 -- Smith & Nephew's (NYSE:SNN) Endoscopy Division today announced the launch of the KINSA RC 5.5 Suture Anchor, designed to provide secure repair of shoulder injuries stemming from tears to the rotator cuff -- the group of muscles and tendons that control shoulder motion.
Surgeons can repair these injuries using arthroscopic -- or minimally invasive -- techniques with specialized instruments and devices such as the KINSA RC Suture Anchor, which re-attaches the torn tissue to restore mobility.
The KINSA RC Suture Anchor is the second in Smith & Nephew Endoscopy's line of KINSA suture anchors. The original KINSA anchor, for treatment of shoulder instability, was released in 2006. Both KINSA anchors encase a sliding, self-locking knot that permits the surgeon to secure the repair without tying knots on top of the tissue. Surgical knots in arthroscopic repairs can sometimes loosen or cause irritation of surrounding tissue. The KINSA RC anchor instead delivers "low profile" repair, without knots or protrusions to interfere with the joint motion.
Successful rotator cuff repair requires that a suture anchor sit securely in the cortical, or dense outer layer of bone, and that the surgeon controls the tension of the sutures that hold repaired tissue in place.
The anchor is well suited for "double-row" fixation, a procedure that clinical studies have shown delivers the superior rotator cuff repair and shoulder mobility. This technique calls for the surgeon to anchor the rotator cuff tissue at several points, distributing the strength of fixation across the shoulder.
A surgeon taps the anchor into the bone surface, and then seats it with a final twist. The surgeon controls the amount of tension applied to the repair by manually tightening the KINSA suture. Surgeons who use competing anchors don't have total control over the tension.
"Its design allows me to properly sink the anchor first, and then apply the amount of tension for optimal tissue-to-bone contact to promote healing," said Dr. Michael Terry, orthopedic surgeon based at the University of Chicago. "This is important because too much tension can interfere with blood flow in the tissue and compromise healing.
"Another benefit of this system is that it is so easy to use," Dr. Terry said. "There are no knots to tie and the instrumentation is simple and familiar."
The KINSA RC anchor is small -- about 1/2-inch in length -- and made from a unique, implantable PEEK-OPTIMA(R) polymer from Invibio(R), which closely matches the density of cortical bone. The implants deliver strong repair but do not show up on X-rays or distort MRIs, as metal anchors would.
"The KINSA RC Suture Anchor enhances our innovative line of shoulder fixation devices, which have been designed to provide the best possible repair for patients, and the most efficient delivery for busy shoulder surgeons," said Joe Darling, senior vice president and general manager of Smith & Nephew Endoscopy's Arthroscopic Repair strategic business unit.
