We retrospectively reviewed seven patients who had undergone a fascial patch repair of massive rotator cuff tears to evaluate efficacy of this surgery between August 2000 and November 2002. The mean age of the seven patients (six males, one female) was 56.7 years (47 to 74 years). Four patients recalled traumatic event. The average duration of time between the onset of symptoms and surgical repair was 25 months. All patients were evaluated before and after surgery based on their JOA score (pain, function [muscle strength and activities of daily living], range of motion, maximum 80 points). The average preoperative JOA score was 39.8 points, and average postoperative score was 66.1 points. There was a significant decrease in pain and significant increases in muscle strength, ability to perform daily activities, and range of motion. Fascial patch repair of massive rotator cuff tears should provide patients pain relief as well as satisfactory functions and range of motion.
