Arthroscopic posterior capsulolabral repair in a beach-chair position.

The authors describe an arthroscopic surgical technique for posterior capsulolabral repair using standard portals while patients are in the beach-chair position. The technique is unique in that the suture anchors are inserted from a superior-to-inferior direction instead of the traditional posterolateral-to-anteromedial direction. It involves the use of a posterolateral or mid-lateral portal through the rotator cuff for suture anchor insertion while viewing from the standard anterior portal. The technique avoids the risk of articular cartilage damage or glenoid rim fracture due to skiving during suture anchor insertion from a posterior or accessory posterior portal.
