n the past several years, our understanding of shoulder instability has evolved and our surgical approaches have correspondingly developed. Our contemporary approaches seek to marry the benefits of a minimally invasive, arthroscopic approach with long-term restoration of shoulder function and a low-risk of recurrence. Despite this evolution, the rate of failure after arthroscopic surgery for shoulder instability remains substantial, and new challenges in the

management of failed arthroscopic stabilization surgeries have ascended, including glenohumeral bone loss. Additionally, the expectations regarding out surgical treatments have grown to not just achieve stability for the joint, but to also restore normal or near-normal kinematics and contact mechanics of the shoulder joint. In this regard, understanding the subjective and objective efficacy and complications of both our nonoperative and surgical approaches for primary and revision instability surgery is critical.

In this issue, we present a number of primary research articles that address many of the current challenges in complex glenohumeral instability. These include studies evaluating the role of immobilization in external rotation on clinical outcomes and anteroposterior stability, the impact of complex, bipolar bone loss on shoulder stability, and the efficacy of remplissage or Latarjet on restoring function and stability, among many other

but also serves as a humble reminder of ‘‘what we don’t know.’’ Future studies must work to fill these gaps, and help us to accomplish both

shoulder stability and joint preservation with normal preinjury kinematics and function.
