Arthroscopy-Assisted Transosseous Lower Trapezius Transfer With Peroneus Longus Autograft Using a Reusable Transosseous Repair System for Massive Irreparable Cuff Tears.

Tendon transfers are preferred in patients with massive, irreparable posterosuperior rotator cuff tears without glenohumeral arthritis. Recently, a surge of lower trapezius transfer over latissimus dorsi transfer has been observed due to its biomechanical superiority. We present an arthroscopy-assisted lower trapezius transfer technique using a reusable transosseous system and a peroneus longus autograft. The reusable repair system and autograft make this technique both accessible and affordable. With its potential to improve patient outcomes and reduce health care costs, this lower trapezius transfer technique is a valuable addition to shoulder surgery. By sharing our experience, we hope to facilitate wider adoption of this approach.
