Arthroscopic and open Bankart repairs provide similar outcomes.

UNLABELLED: Recurrent instability after arthroscopic Bankart repair has decreased, largely because of improvements in surgical technique. We wanted to know whether there were differences in functional outcomes (using a validated outcomes measure) in patients who had arthroscopic Bankart repair or open Bankart repair for recurrent anterior glenohumeral instability. We retrospectively reviewed 106 patients who had a Bankart repair for recurrent anterior glenohumeral instability from 1998-2001. Of the 93 patients included, 69 patients had arthroscopic Bankart repair and 24 patients had open Bankart repair. The indications for surgery in the two groups were similar. The average age of the patients was 29.9 years (arthroscopic Bankart repair, 31 years; open Bankart repair, 28 years). The followup ranged from 24-77 months. The average modified American Shoulder and Elbow Surgeons score (PENN score) for pain, satisfaction, and function were 26.3, 8.5, and 55.1, respectively, in the arthroscopic Bankart repair group and 26.6, 8.8, and 54.2, respectively, in the open Bankart repair group. The total score was 90 in the arthroscopic Bankart repair group and 89.5 in the open Bankart repair group. Recurrent instability occurred in one patient in each group. We found no difference in outcomes between the arthroscopic and open Bankart repair groups using patient-assessed outcomes.
