The most common surgical technique in traumatic anterior shoulder instability is the arthroscopic Bankart repair, which has excellent short-term results. The long-term results of the arthroscopic Bankart repair are less frequently studied, with a high recurrence rate of 23% to 35%. The aim of this study was to evaluate the medium-term to long-term results of arthroscopic Bankart repair using suture anchors and to identify specific risk factors for recurrent instability. Included were 147 patients after traumatic anterior shoulder dislocation who underwent an arthroscopic Bankart repair. The primary outcome was recurrent instability, defined as dislocation or subluxation as perceived by the patients. The secondary outcome was subjective shoulder stability and function as well as quality of life, evaluated using the Western Ontario Shoulder Instability Index, the Simple Shoulder Test, and the 12-Item Short Form Health Survey. Prognostic factors for recurrent instability were analyzed. Recurrent instability occurred in 22% of patients with a mean follow-up of 6.3 years. Survival at 5 and 10 years without recurrent instability was 79% and 78%, respectively (95% confidence interval, 72%-85% and 71%-85%, respectively). The Western Ontario Shoulder Instability Index score, the Simple Shoulder Test score, and the 12-item Short Form Physical Component Summary improved significantly in the nonrecurrence group (P
