title: A 4-portal arthroscopic stabilization in posterior shoulder instability.
abstract: The purpose of this study was to present an arthroscopic stabilization technique with 4 portals for posterior instability used in 11 patients (13 shoulders). There were 7 male and 4 female patients. All patients had an arthroscopic labral suture with anchors and capsular plication with 4 portals. The follow-up period averaged 34 months. No complication or recurrence of instability was noted. A moderate loss of range of motion was noted in 4 shoulders and moderate pain in 2 shoulders. All patients were satisfied. According to the literature, the rate of recurrence of instability is currently lower than 12% when a labral suture and capsular plication are performed. Our results for pain and range of motion are similar to those described in recent publications. However, we think that the 4-portal technique allows a facilitated access to the posteroinferior part of the glenoid and reduces the rate of postoperative instability.
