Description

Basic treatment for rotator cuff tears is repair of the rotator cuff. However, in patients with small tears in whom the ability to elevate is sufficiently maintained despite a marked painful arc, we have not always performed repair of the rotator cuff, but have performed arthroscopic subacromial decompression (ASD), considering that ASD facilitates pain control and improvement in function. In this study, we reported on the treatment results, with a mean postoperative follow-up of more than 4 years. The subjects were 10 patients (10shoulders),7 males and 3 females, with a mean age of 56.9 years old and a mean postoperative follow-up of 54.7months. In all subjects, small tears were confirmed under an arthroscope, and an ASD was performed. Surgery was indicated for patients with small tears measuring 2 cm or less in diameter in whom active elevation was possible (including that after injection of a topical anesthetic). The mean preoperative and postoperative JOA scores were 64.8 and 92.9 points, respectively, with a 28.1 point increase. Concerning the patient's satisfaction, most patients lived in comfort, and a patient achieved rehabilitation as a professional kick boxer.<br>(Conclusion) Arthroscopic suture for small tears has been reported; however, this procedure is not simple, and requires a long duration. ASD alone may achieve long-term good results in patients with small rotator cuff tears when it is adequately indicated.
