Few studies have been evaluated the arthroscopical repair for subscapularis tendon tear. The purpose of this study was to evaluate the clinical outcome of arthroscopic repair for subscapularis tendon tear. We treated 137 rotator cuff repair from 2003 to 2007. Among them, 15 shoulders with subscapularis tendon tear were treated by arthroscopic repair, 12 shoulders were assesed. The cases were 8 males and 4 females, with an averaged age of 62 years old. The mean follow-up period was 16 months. Three cases were subscapularis tendon tear only, 6 cases were concomitamt supraspinatous tear, and 3 cases were concomitamt supraspinatous and infraspinatous tears. 10 cases were repaired using suture anchors and 2 cases were repaired using side to side stiches. The clinical evaluation was performed using the JOA score, lift-off test and berry-press test. The range of motion and muscle strength were evaluated by Cybex. The average postoperative JOA score increased from 52 points to 91 points significantly. The clinical results were excellent in 6 cases, good in 3, fair in 2, poor in 1. Preoperatively, the lift-off test was positive in 8 shoulders and the berry-press test was positive in 11 shoulders. Postoperatively, the lift-off test was positive in 1 shoulder and the berry-press test was positive in 1 shoulder. The clinical outcome of arthroscopic repair for subscapularis tendon tear was satisfactory.
