Shoulder FAQ

Question:

I've heard that surgeons are starting to use new and better ways to repair rotator cuff tears. I've been told I have a tear so bad it simply can't be repaired. Is that still true? Are these new techniques for people like me? I'm still young enough I want to keep everything well greased and going.

Answer:

Large, full-thickness tears of the rotator cuff can be very challenging for patient and surgeons alike. Loss of motion and loss of strength leads to loss of function for the patient. Finding a way to repair the problem without re-tears and surgical failure is a goal surgeons strive for. In a recent report from Duke University, the successful use of a regenerative tissue matrix for 24 patients with massive irreparable rotator cuff tears is described. A regenerative tissue matrix is the use of donor tissue placed as a scaffold to help the repair along. It is used when the torn tendon has retracted (pulled back) so far from the bone that it cannot be stretched back and stitched back down. By placing graft tissue between the end of the torn tendon and the shoulder bone, the surgeon is able to make a "bridge" and complete the repair. With this donor tissue in place, collagen fibers and blood vessels form to assist healing at the cellular level. This may be what you have heard about. Patients like yourself who previously would not have been candidates for surgery and therefore unable to regain shoulder motion, strength, and function suddenly have a new opportunity for repair and recovery. In fact, if the results of these 24 patients are any indication, this technique is safe and effective without infection or tissue rejection. There are some "yes, buts" to consider -- meaning not everyone with an inoperable, irreparable rotator cuff tear can have this procedure. The patients in this study were selected very carefully for success. They did not have any shoulder arthritis. The tendon tear had not filled in with fat tissue. And for the most part, they still had fairly good active range of motion despite the rotator cuff damage. The use of human dermal allograft (skin harvested from a donor) in this study is not approved by the Food and Drug Administration (FDA) for use as an augmentation procedure of this type. This means that the surgical technique presented in this study is therefore considered "off label." Even so, the technique was successful with good results. Three-fourths of the group had a fully intact repair as shown by ultrasound studies. The rest of the patients had at least a partially repaired rotator cuff. There was no one in the group who ended up with a complete tear after this procedure. Everyone was satisfied with their results and said they would do it again if given a second chance. They all reported less pain, more motion, and better overall function. Follow-up was extended over a period of time from 29 to 40 months (two to three and a quarter years). The authors concluded that the use of extracellular matrix scaffolds in the repair of massive rotator cuff tears is new and still experimental. But this approach offers hope to those who previously had no opportunity for surgical repair. The successful results of this small study may open doors for future studies to expand the number and types of patients who might benefit from this procedure. Anil K. Gupta, MD, MBA, et al.
