Purpose
Arthroscopic repair of rotator cuff tears are many techniques that have been developed to improve the initial postoperative strength of the repair. There was a doubt that current arthroscopic cuff repairs using a single row of suture anchors reproduce insufficient area of the anatomic cuff insertion, and concerns about failure of fixation often lead surgeons to limit early motion. Newer technique of double-row repair in arthroscopic treatment may provide initial stronger fixation and more contact with bone at the repair site than single-row repair did. We studied the comparison between clinical outcomes of arthroscopic single- and double-row repair in cuff tears at 1year postoperatively. Materials and methods: We retrospectively analyzed 40 shoulders with single-row repair and 38 shoulders with double-row repair of full-thickness rotator cuff tears between May 2002 and October 2004. Out of total 78 shoulders, 42 (54%) were male patients and 36 (46%) were female patients and the mean age at surgery was 56 years. All patients were diagnosed by physical examination and MRI. At 1year’ follow-up after operation, we evaluated with the ASES and the Constant scoring system, and measured muscle power of abduction, internal and external rotation of the affected shoulder then compared with each other. Results: Mean ASES scores and Constant scores in double-row repair group improved more than single-row repair group significantly at 1year postoperatively. Muscle power of abduction and internal rotation, especially abduction power, improved more significantly in double-row repair group than in single-row repair. Conclusion: Arthroscopic double-row repair for the full thickness rotator cuff tear may be a superior technique, which showed better clinical outcomes and restoration of muscle power compared with single-row repair at relatively short period of postoperative follow-up. Restoration of footprint close to normal anatomy by double-row repair seems to play an important role in the recovery of muscle strength. |
