Open Bankart Repair for the Treatment of Anterior Shoulder Instability without Substantial Osseous Glenoid Defects: Results After a Minimum Follow-up of Twenty Years.

Background: Neglected osseous glenoid defects are thought to be one of the reasons for the reported high rates of recurrent instability at long-term follow-up after Bankart repair. We hypothesized that open Bankart repair for the treatment of anterior glenohumeral instability in the absence of a substantial osseous glenoid defect would result in a lower long-term recurrence rate than has been reported in previous long-term studies.

Methods: Forty-seven patients were treated with a primary modified open Bankart repair for recurrent anterior shoulder instability between 1989 and 1994.
