The Arthroscopic Bankart-Plus Procedure for Treatment of Anterior Shoulder Instability With Small to Intermediate Glenoid Defects.

To date, specific surgical procedures are available for the treatment of anterior shoulder instability with substantial bony glenoid defects, as well as for patients without osseous lesions. However, specific treatment options are lacking for the frequently observed small to intermediate glenoid defects, which may not necessitate glenoid reconstruction surgery according to current guidelines but can still jeopardize the outcome after mere soft-tissue stabilization procedures. This article describes the so-called arthroscopic Bankart-Plus procedure for the treatment of anterior shoulder instability with small to intermediate bony glenoid defects. In addition to the conventional capsulolabral repair, an allogeneic demineralized spongy bone matrix is inserted between the glenoid neck and the labrum with the aim of compensating for the glenoid bone loss by increasing the volume of the labrum and thus its stabilizing effect.
