Arthroscopic Noninvasive Transtendon Double-Pulley Suture Bridge Repair of Partial Articular Supraspinatus Tendon Avulsions

Currently, transtendon is a widely used technique for PASTA (partial articular supraspinatus tendon avulsion) lesions. However, tendon trauma on the bursal layer is a drawback in transtendon repair. Therefore, we present a noninvasive transtendon double-pulley suture bridge that uses inverted mattress sutures as medial-row sutures instead of a medial-row anchor. In the treatment of PASTA lesions, the bursal layer can be completely retained, 6 sets of a double-pulley suture bridge can provide sufficient initial strength of tendon fixation, and the surgical difficulty is also greatly reduced.
