Recurrent post-traumatic anterior shoulder dislocation--open versus arthroscopic repair.

A total of 41 consecutive patients (11 women and 30 men, median age 29 (18-51) years) with unilateral, isolated, posttraumatic, recurrent anterior shoulder dislocation and a Bankart lesion were operatively repaired, either by an arthroscopic technique including a capsular plication, or by an open procedure with Mitec anchors. All the patients were followed prospectively and evaluated after a median of 36 (30-52) months follow-up by a "blind" observer. Nineteen patients in each group had excellent or good results, and one in each group was graded as fair. One patient in the arthroscopic group had a traumatic dislocation 5 months after the operation and was graded as poor. Three patients experienced subluxations postoperatively, one in the arthroscopic and two in the open group. There was no significant difference in anterior-posterior shoulder laxity measured objectively with Donjoy. The open Bankart repair group had a statistically significantly longer hospitalization (P = 0.001), a slight decrease in external range of motion, and more frequent cosmetic complaints. Apart from this, the results revealed no major differences between the two methods after a median of 36 months in this selected group of patients with longstanding problems.
