Rotator Cuff Tears Treated With Long Head of the Biceps Reinforcement

A prospective randomized study will be carried out in a 1:1 ratio between groups. Patients with large and extensive rotator cuff injuries will be selected at the Shoulder and Elbow clinic of Pedro Ernesto University Hospital (HUPE-UERJ), during outpatient care. Patients with an intact long head of the biceps will be randomized into two groups, according to the use or not of the tendon: complete repair with LHB tendon reinforcement and complete repair without reinforcement. All patients will be operated by the same surgeon. All selected patients will be explained what the research is about by a research assistant not involved in the treatment and will be offered the option to participate or not. The "American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form" (ASES) scale will be adopted as the primary outcome. The "Modified University of California at Los Angeles Shoulder Rating Scale" (UCLA) and the assessment of tendon healing with magnetic resonance imaging at 6 months after surgery, using the classification of Sugaya et al. will be secondary outcomes.
