Multidirectional Shoulder Instability: Arthroscopic Labral Augmentation.

Capsulolabral augmentation is one of the most used arthroscopic techniques to address multidirectional instability of the shoulder. Given the thin and weak capsule seen in the affected patients, reconstruction in this subset of patients can be particularly challenging. This arthroscopic technique aims to reduce the capsular volume and deepen the glenoid socket through the creation of a particularly voluminous "bumper" along the glenoid bone. Increasing the depth of the glenoid facilitates a concavity-compression stabilizing effect and, therefore, shoulder stability, especially midrange stability. This technique aims to augment the bump of the standard capsulolabral reconstruction by using a resorbable surgical mesh derived from porcine skin.
