Can arthroscopic revision surgery for shoulder instability be a fair option?

Background: the aim of this study was to evaluate the role of arthroscopic capsuloplasty in the treatment of failed primary arthroscopic treatment of glenohumeral instability.Methods: we retrospectively examined at a minimum of 3-years follow-up 22 patients who underwent arthroscopic treatment between 1999 and 2007 who had recurrent anterior shoulder instability with a post-surgical failure.A statistical analysis was performed to evaluate which variable could influence the definitive result and clinical outcomes at final follow-up.A p value of less than 0.05 was considered significant.Results: we observed after revision surgery an overall failure rate of 8/22 (36.4%) including frank dislocations, subluxations and also apprehension that seriously inhibit the patient's quality of life.No significant differences were observed in the examined parameters.Conclusions: according to our outcomes we gen-erally do not recommend an arthroscopic revision procedure for failed instability surgery.
