Arthroscopic Augmentation With Subscapularis Tendon in Anterior Shoulder Instability With Capsulolabral Deficiency
Marco Maiotti – Carlo Massoni
Abstract
The treatment of chronic shoulder instability with poor quality of the anterior capsulolabral tissue is still controversial. In these cases the Latarjet procedure is certainly more effective in preventing recurrence than an arthroscopic capsular repair. However, several studies have reported a variety of severe complications related to the Latarjet procedure because of the use of bone augmentation and hardware implantation; moreover, the arthroscopic version of the Latarjet procedure is technically difficult and potentially dangerous because of the proximity of neurovascular structures. The aim of this report is to describe an innovative arthroscopic technique consisting of an augmentation of the anterior capsulolabral tissue using the articular portion of the subscapularis tendon and knotless suture anchors paired with high-strength tape for its fixation to the anterior glenoid edge. In the absence of severe bone deficiency of the anterior glenoid edge, this procedure can minimize arthroscopic technique failures, restoring the anterior capsulolabral wall without any significant reduction of shoulder functionality.
