Background: The purpose of this study was to evaluate the clinical outcome and repaired cuff integrity after arthroscopic rotator cuff repair(ARCR). Methods: We evaluated 68 shoulders in 67 patients, including 39 males and 29 females, who underwent ARCR between March 2006 and May 2009 and were followed for a minimum of 2 years. The average age at the time of operation was 63.7 years old(range, 43-77) and mean follow-up period was 24.7 months(range, 24-36). There were 20 small, 30 medium, 11 large and 7 massive tears. For 5 severe retracted massive tears, advancement of the supraspinatus and infraspinatus muscle(modified Debeyre-Patte procedure) was added. We evaluated the clinical outcome by Japanese Orthopaedic Assocoation(JOA) score. The repaired cuff integrity was evaluated by Sugaya's MR classification. Results: The mean JOA score was significantly improved from 70.3 points preoperatively to 97.6 points postoperatively. Re-tear was observed in 12 shoulders( 17.7%). The re-tear rate was 0% in small, 20% in medium, 36.3% in large and 28.3% in massive tears. The mean JOA score in the repaired group (98.1 points )was higher than that in the re-tear group(95.4 points). Conclusion: The clinical results of ARCR were satisfactory. In order to reduce re-tear, some resources have to be considered.
