We developed a new rotator cuff repair method, namely compression double-row repair, which was combined the double-row repair with suture-bridge method. The purpose of this study was to compare the functional and structural outcomes after arthroscopic rotator cuff repair between compression double-row, double-row, and single-row method. A consecutive series of 96 shoulders in 94 patients with full-thickness rotator cuff tears was evaluated using the rating scale of the Japanese Orthopaedic Association (JOA) scores at an average of 11.3 months (range, 6 to 36 months) after arthroscopic rotator cuff repair. Fifty shoulders were repaired using the compression double-row technique, 16 shoulders using double-row technique, and 30 shoulders using the single-row technique. Postoperative cuff integrity was determined by Sugaya's classification of magnetic resonance imaging. Retear rate after arthroscopic rotator cuff repair was 8.0% of compression double-row, 18.8%of double-row, and 10.0% of single-row technique. Only in large and massive rotator cuff tears, retear rate was 12.5% of compression double-row, 33.3%of double-row, and 28.6% of single-row technique. Postoperative JOA score in patients with retear was significantly lower than that in patients without retaer. Compression double-row method, which had a low rate of postoperative retear, is effective option for arthroscopic rotator cuff repair because postoperative functional outcome in patients with retaer is inferior to that without retear.
