Clinical Results of Arthroscopic-Assisted Lower Trapezius Tendon Transfer for Massive, Irreparable Rotator Cuff Tears

This study aimed to describe a modified technique for arthroscopic-assisted transfer of the lower trapezius tendon in a selected group of patients with irreparable rotator cuff tears and to evaluate its short-term results.

Patients scheduled for surgery will undergo evaluation one day before the surgical procedure and again at the six-month postoperative mark. Pain intensity will be assessed using the Visual Analog Scale (VAS), while shoulder function will be evaluated using both the University of California, Los Angeles (UCLA) Shoulder Score and the Constant-Murley Shoulder Score.
