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.

Inclusion Criteria: * patients with massive, chronic (\>6 months), irreparable rotator cuff tears; * patients with no concomitant irreparable subscapularis tears; * patients who underwent a trial of at least 6-month period of conservative treatment with no benefit; * patients with a stage 3 or greater degree of supraspinatus muscle fatty infiltration; Exclusion Criteria: * patients with glenohumeral arthritis; * patients with adhesive capsulitis or passive joint motion restriction * patients with neurologic deficits
