All–Extra-articular Repair of Anterosuperior Rotator Cuff Tears

Abstract

Anterosuperior rotator cuff tears involve the subscapularis tendon, supraspinatus tendon, and rotator interval. The long head of the biceps is usually affected and unstable in these complex lesions. Arthroscopic repair of anterosuperior rotator cuff tears often consists of 2 different procedures. Whereas the subscapularis tendon is reconstructed under intra-articular visualization, the supraspinatus tendon is reconstructed under extra-articular visualization. The rotator interval is often sacrificed to improve visualization and instrumentation. The presented technique uses an all–extra-articular approach, which helps to reconstruct these complex rotator cuff lesions in their whole extent without switching from the inside to the outside of the shoulder joint. The preservation of the rotator interval leads to a more stable and anatomic reconstruction.
