The purpose of this study was to evaluate the minimum 1-year-follow-up result of arthroscopic rotator cuff repair using suture anchor (ARCR) for incomplete or complete rotator cuff tear and made a comparison of the result between with and without preoperative stiff shoulder. We performed ARCR alone for the shoulders without stiff shoulder (group N) and combined ARCR and capsular release (ACR) for the shoulders with stiff shoulder (group S). We retrospectively studied 114 shoulders of 110 patients in group N and 32 shoulders of 30 patients in group S. The average age at operation was 60.5 years old (range, 32-77) in group N and 57.4 years old (range, 30-71) in group S. The average follow-up period was 15.9 months (range, 12-52) in group N and 16.9 months (range, 12-48) in group S. A comparison of the clinical results between group N and group S was made. The averaged JOA score changed from 63.6 before surgery to 94.9 after surgery in group N, and from 54.1 before surgery to 93.1 after surgery in group S. Preoperatively the JOA score and the shoulder motion in group S was significantly lower than in group N. No significant differences were observed between group N and group S in the shoulder range of motion, JOA score, or cuff integrity on MRI at the time of the final follow-up. This study suggested that combined ARCR and ACR for rotator cuff tear with stiff shoulder is a reliable procedure to gain clinical outcomes the same as ARCR for rotator cuff tear without stiff shoulder.
