According to recently reported outcome studies, functional outcomes after arthroscopic rotator cuff repair are reasonable and comparable to open or mini-open techniques. We report the functional outcomes after arthroscopic rotator cuff repair of 10 consecutive patients. The average age was 53.9(range 46-59) years. There was a significant improvement of the function of the shoulder when the preoperative scores were compared with those at the time of at least six months follow-up (range of 6 months to 18 months). With the UCLA rating scale, the average total score increased from preoperative 9.8 (range, 6-15) to postoperative 32.6 (range,23-35). With the use of ASES shoulder index, the average total score improved from 14.6 range, 1.6-35) to 92.3 (range,66.6 to 100). We concluded that arthroscopic rotator cuff repair is a treatment method in selective patients with symptomatic rotator cuff pathology to alleviate shoulder pain and improve function.
