Arthroscopic soft tissue stabilization of posttraumatic anterior shoulder instability. Techniques, limitations and long-term results

Arthroscopic soft tissue stabilization is a well-established and broadly accepted procedure to treat posttraumatic shoulder instability. Advantages in comparison to open stabilization procedures include improved visualization of the structural damage and a less invasive approach. Technical developments in recent years have led to further improvement of the arthroscopic technique for shoulder instability. This article presents a description of principles and new developments as it contains basic techniques including patient positioning, access portals, preparation of the glenoid bone, soft tissue handling and shuttle techniques. Modern suture anchor systems to achieve arthroscopic stabilization with the corresponding advantages and disadvantages are also presented. Furthermore, the limitations and long-term results of arthroscopic soft tissue stabilization are discussed.
