Early arthroscopic treatment of primary traumatic anterior shoulder dislocation. A follow-up study.

This study evaluates the results of early arthroscopic Bankart repair in patients with primary traumatic anterior dislocation of the shoulder. The patients' age range was 17-34 years. Arthroscopic Bankart repair was performed within 12 days after the dislocation. First follow-up was at 18 months. According to Rowe's score, 11 patients (73%) were excellent, 3 (20%) were good and 1 (7%) was poor. The median external rotation deficit was 4 degrees in the adducted position. At a second follow-up at 34 months, two patients had redislocated. Both of these patients had severe generalized joint laxity. Another patient reported frequent subluxations. We conclude that in young patients with primary anterior traumatic shoulder dislocation, early arthroscopic Bankart repair implies a low recurrence rate and restores shoulder function to normal. Generalized joint laxity could indicate an increased risk for recurrent dislocation.
