Background: Treatment of recurrent shoulder dislocation with open technique has a long successful history in orthopaedic surgery. Arthroscopic repair, however, has a much shorter history especially in Iran. This is a short-term follow-up study of such an operation in Iran.Methods: Forty patients (39 males, 1 female) with recurrent anterior shoulder dislocation who had undergone arthroscopic stabilization over a two-year period were evaluated in a retrospective study. The cases had a mean age of 25.3 years, and had 15.5 months (6-30 months) average follow-up. The assessment scores were “The University of California-Los Angeles” (UCLA), “Rowe” and “American Shoulder and Elbow Society Scores” (ASES).Results: Mean Rowe score was 95.5 (77-100) with excellent scores in 32 patients, good in 4, fair in 3 and poor in one. Mean UCLA score was 33.3 (25-35), with good and excellent results in all but 4 cases. ASES was 2-3 in 3 patients, and the rest being painless and without any symptoms. Thirty six patients returned to their previous levels of activity, and achieved good results the results were fair in 3, and poor in one patient who had recurrent instability.Conclusions: Short-term results of arthroscopic repair of anterior shoulder instability are encouraging.
