Arthroscopic-Assisted Lower Trapezius Tendon Transfer for Irreparable Posterosuperior Rotator Cuff Tears Using a Quadricipital Tendon Allograft and a Double-Row Construct

Lower trapezius transfer is a joint salvage treatment option for irreparable posterosuperior rotator cuff tears in relatively young patients. It requires the use of a tendinous graft to bridge the gap between the lower trapezius and the greater tuberosity. Inlay fixation of hamstring autografts and onlay single-row fixation of Achilles allografts have been described in the literature. This technical note describes an arthroscopic-assisted lower trapezius transfer using a quadricipital tendon allograft fixed with an onlay knotless double-row construct.
