Arthroscopic glenoid labral repair with an oblique mattress configuration.

There have been several arthroscopic techniques described in the literature regarding the passage of sutures for an arthroscopic glenoid labral repair. With simple suture passage when tying knots, there is a concern of internal knot impingement, especially in the posterosuperior labrum. On the other hand, with simple suture passage with knotless technology, there is a concern of leaving the anchor hole exposed in the glenohumeral joint space, especially with anchors that are degradable over time. Whereas a horizontal mattress configuration may address these 2 issues in most cases, there is the issue of tissue cut-through with the labral tissue fibers being in the same plane as the horizontal mattress sutures. The purpose of this report is to describe the oblique mattress configuration, which allows the passage of suture through multiple labral tissue planes, covers up the anchor holes with labral tissue, and maintains the knots away from the articular surface if knots are tied.
