Abstract
Acromioclavicular joint injuries account for 9% of shoulder girdle injuries and are most often associated with direct blows to the shoulder or axially directed forces onto the ipsilateral extremity. Type IV, V, and VI injuries are generally managed surgically, whereas type I and II injuries are treated with sling immobilization, early shoulder range of motion, and physical therapy. Type III injuries are more controversial but are generally managed surgically in the active and high-demand patient. When surgical treatment is indicated, the primary goal of a coracoclavicular (CC) ligament reconstruction is to restore anatomic reduction of the acromioclavicular joint and reconstruct the biomechanical forces of the CC ligaments. Many open surgical techniques are currently used to achieve these goals but can increase patient morbidity. We describe a technique for an all-arthroscopic CC ligament reconstruction using a semitendinosus allograft and BioComposite tenodesis screws (Arthrex) without disruption of the deltoid attachment onto the distal clavicle.
