Arthroscopic Posterior Glenohumeral Capsular Augmentation With Gracilis Tendon Allograft.

ABSTRACT

Recurrent shoulder instability complicated by capsular insufficiency due to underlying soft-tissue disorders or multiple prior failed surgical procedures poses a challenging surgical problem. Traditional capsulolabral soft-tissue reconstruction techniques are less effective in this setting, and bony procedures sacrifice normal anatomic relations. The described arthroscopic technique aims to prevent instability while maintaining range of motion through creation of a soft-tissue allograft "sling" augmenting the posterior glenohumeral capsule.
