Four-quadrant approach to capsulolabral repair: an arthroscopic road map to the glenoid.
Advancing technology, improved instrumentation, and a desire to address intra-articular pathology with a minimally invasive approach have driven the expansion of arthroscopic shoulder surgery in the past 2 decades. Proponents cite greatly improved visualization, lack of the need to perform a capsulotomy, fewer subscapularis issues postoperatively, and improved access to the entire glenohumeral joint. Our understanding and recognition of glenohumeral joint pathology have improved, and our ability to appropriately treat it has also improved. Aside from the anteroinferior and superior capsulolabral injury, orthopaedic surgeons have encountered and are able to address combined lesions, posterior labral tears, 270 degrees to 360 degrees labral tears, capsular laxity, humeral avulsion of the glenohumeral ligaments, associated glenoid or humeral bone loss, and partial-thickness rotator cuff tears. To adequately address the extent of pathology encountered in a shoulder instability case, access to the inferior, posteroinferior, and posterior aspects is necessary. In this technical article we present a simplified approach using safe access points by dividing the glenohumeral joint into 4 quadrants that allows for ease of instrumentation and implant placement. This will provide a blueprint for the treatment of capsulolabral injuries. In addition to portal selection and location, we will discuss several instruments we believe are advantageous in tissue manipulation and suture management.
