Arthroscopic Repair of a Circumferential 360° Labral Tear

Injuries to the glenoid labrum can result in shoulder instability and pain. These lesions may occur anywhere around the glenoid labrum, and thus, the arthroscopist must be prepared to approach all aspects of the glenoid from multiple angles. The pan-labral or circumferential (360°) tear of the glenoid labrum presents a unique challenge to even the experienced arthroscopist. The extent of the lesion requires the use of accessory portals and percutaneous techniques to establish adequate visualization and to facilitate the proper trajectory for anchor placement. The pan-labral tear also demands intraoperative planning throughout the repair to ensure proper tensioning and alignment of the labrum and capsular tissue. The purposes of this article are to report a technique for repairing a pan-labral lesion and to emphasize the use of accessory portals and percutaneous techniques for complete access to the glenoid.
