Recurrent instability after operative intervention for traumatic unidirectional anterior shoulder instability is a difficult problem for both the patient and treating physician. Whereas recurrence rates for open surgery have been reported as less than 10%, the results from arthroscopic treatment are more variable, ranging from 0% to 43%.
Treatment options for failed shoulder instability repair include conservative care with physical therapy, bracing and activity modifications, and revision surgical intervention. Revision surgery of failed shoulder instability repair has been addressed with open procedures with failure rates ranging from 8% to 39%. To our knowledge, the clinical outcome of revision arthroscopic surgery for failed instability repair of the shoulder is not well known. In fact, there is only 1 clinical study on this topic in the literature. The purpose of this study was to report our experience with this difficult patient population and to critically evaluate the outcome of our arthroscopic technique in revision cases. Our hypothesis was that arthroscopic techniques would have similar results with regard to elimination of instability when compared with more traditional open techniques.
