Abstract
Massive and irreparable rotator cuff tears remain a difficult condition to treat. Fatty infiltration of the muscles and excessive retraction of the tendons predispose to high failure rates of arthroscopic repair techniques. In recent years, studies on the superior capsule have shown that it plays a key role in reducing superior humeral head translation and restoring balance to the force couples required for dynamic shoulder function. Superior capsule reconstruction has become common in clinical practice. Several techniques with different types of grafts have been described, such as fascia lata autograft, dermal allograft patch, and long head of the biceps tendon autograft. More recently, an open technique with semitendinosus tendon autograft has been proposed. Our aim is to describe an all-arthroscopic technique for superior capsule reconstruction using a doubled semitendinosus tendon autograft in a box-shaped configuration. We believe that the technique can combine the advantages of other techniques, such as graft availability, low harvest-site morbidity, limited cost, and mechanical strength.
