Open surgical treatment for primary anterior glenohumeral instability is reliable and time-tested and can yield excellent clinical results. With advancements in arthroscopic technique, there has been a growing trend toward arthroscopic treatment of anterior shoulder instability. In many instances, arthroscopic treatment is preferred by patients and surgeons because it is minimally invasive, obviating the need for releasing and repairing the subscapularis; because it allows better identification and treatment of associated pathological conditions; and because it decreases morbidity and facilitates an outpatient approach. Furthermore, recent studies have demonstrated that the results of arthroscopic treatment of recurrent traumatic anterior instability are comparable with those achieved historically with open procedures.
