Patient Selection
From February 1999 to April 2002, 132 consecutive shoulders in 130 patients who failed conservative treatment underwent arthroscopic primary rotator cuff repair by a single surgeon (H.S.). Full-thickness or partial-thickness defects were confirmed by preoperative MRI in all patients. The criteria for inclusion in this study were a full-thickness rotator cuff tear confirmed during surgery and no major associated pathology that would need to be addressed at the time of arthroscopic surgery, such
Functional Outcome
Both rating systems reflected a significant improvement in the status of the shoulders when the preoperative scores were compared with those at the time of the final follow-up (P < .01). The average total score increased from preoperative 14.8 (range, 3-22) to 32.4 (range, 16-35) in the single-row group and from 14.4 (range, 5-21) to 33.1 (range, 19-35) in the dual-row group with use of the UCLA rating scale. The average total score improved from 45.8 (range, 5-70) to 93.0 (range, 45-100) in
Discussion
Although patient population and surgical technique were different, Galatz et al.10 recently reported a surprisingly poor structural outcome after arthroscopic large and massive rotator cuff tears. In their series, 17 of 18 patients (94%) had a recurrent defect as evaluated through ultrasonography performed 2 years postoperatively. They mentioned that arthroscopic repair of the rotator cuff might not yield as strong a repair as traditional open or mini-open repair. They also suggested that an
