title: Can arthroscopic revision surgery for shoulder instability be a fair option?
abstract: 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 generally do not recommend an arthroscopic revision procedure for failed instability surgery.
