Partial Superior Capsular Reconstruction to Augment Arthroscopic Repair of Massive Rotator Cuff Tears Using Autogenous Biceps Tendon: Effect on Retear Rate.

Background: Massive rotator cuff tears have a high incidence of postoperative retear that can reach 90%. It is still unclear which intervention may reduce the incidence of retear and improve the functional and clinical outcomes.

Purpose/hypothesis: The purpose of this study was to investigate the clinical and structural outcomes at 2 years after repair of reparable massive rotator cuff tears with and without the use of partial superior capsular reconstruction (pSCR), using the autologous long head of the biceps tendon (LHBT) as a graft.
