If the tear affects less than half of the rotator cuff tendon (grade 1 or 2 tear), you'll probably have good results. Ninety percent of patients with minor tears show immediate improvement from this procedure. And the results seem to last. In a recent study, most patients continued to be pain free when rechecked up to five years after surgery. Patients showed good shoulder strength and motion and were able to do all their activities. Patients followed for up to 10 years didn't show any worsening in the shoulder area.

When this treatment fails, it fails right away, and the results do not get better over time. Failure is more likely for larger tears and those located on the top surface of the rotator cuff.
