Smith & Nephew Endoscopy's KINSA(R) RC Suture Anchor Designed for Secure Repair of Rotator Cuff Injuries
Surgeons can repair these injuries using arthroscopic -- or minimallyinvasive -- techniques with specialized instruments and devices such as theKINSA RC Suture Anchor, which re-attaches the torn tissue to restore mobility.
The KINSA RC Suture Anchor is the second in Smith & Nephew Endoscopy'sline of KINSA suture anchors. The original KINSA anchor, for treatment ofshoulder instability, was released in 2006. Both KINSA anchors encase asliding, self-locking knot that permits the surgeon to secure the repairwithout tying knots on top of the tissue. Surgical knots in arthroscopicrepairs can sometimes loosen or cause irritation of surrounding tissue. TheKINSA RC anchor instead delivers "low profile" repair, without knots orprotrusions to interfere with the joint motion.
Successful rotator cuff repair requires that a suture anchor sit securelyin the cortical, or dense outer layer of bone, and that the surgeon controlsthe tension of the sutures that hold repaired tissue in place.
The anchor is well suited for "double-row" fixation, a procedure thatclinical studies have shown delivers the superior rotator cuff repair andshoulder mobility. This technique calls for the surgeon to anchor the rotatorcuff tissue at several points, distributing the strength of fixation acrossthe shoulder.
A surgeon taps the anchor into the bone surface, and then seats it with afinal twist. The surgeon controls the amount of tension applied to the repairby manually tightening the KINSA suture. Surgeons who use competing anchorsdon't have total control over the tension.
"Its design allows me to properly sink the anchor first, and then applythe 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 inthe tissue and compromise healing.
"Another benefit of this system is that it is so easy to use," Dr. Terrysaid. "There are no knots to tie and the instrumentation is simple andfamiliar."
The KINSA RC anchor is small -- about 1/2-inch in length -- and made froma unique, implantable PEEK-OPTIMA(R) polymer from Invibio(R), which closelymatches the density of cortical bone. The implants deliver strong repair butdo not show up on X-rays or distort MRIs, as metal anchors would.
"The KINSA RC Suture Anchor enhances our innovative line of shoulderfixation devices, which have been designed to provide the best possible repairfor patients, and the most efficient delivery for busy shoulder surgeons,"said Joe Darling, senior vice president and general manager of Smith & NephewEndoscopy's Arthroscopic Repair strategic business unit.
