In the absence of significant glenoid bone loss, arthroscopic anterior capsulolabral repair is widely accepted as the treatment of choice in patients undergoing primary surgery for shoulder instability. However, recurrent shoulder instability following primary shoulder stabilization presents a difficult problem for both the patient and the surgeon. Revision shoulder stabilization has historically been treated via open surgery, with the reported rates of recurrent instability following open revision Bankart repair range from 0 to 39 %. More recently, arthroscopic revision stabilization for recurrent shoulder instability has become more popular secondary to increased surgeon familiarity with arthroscopic techniques and improvements in arthroscopic instrumentation and implants. Lesions that were once considered to be an indication for open surgery are now treatable arthroscopically. In addition, arthroscopic approaches are less invasive and with minimal alteration of the subscapularis. Subsequently, the reduced morbidity of arthroscopic surgery may result in early functional rehabilitation and improved range of motion.
The purpose of this study was to determine clinical outcomes in patients following revision arthroscopic anterior capsulolabral stabilization of the shoulder. The specific aims were to determine the rate of failure, identify risk factors for recurrence of instability, and report on subjective patient-reported outcomes. The hypothesis was that revision arthroscopic stabilization would offer satisfactory clinical outcomes in appropriately selected patients.
