ARTHROSCOPIC REPAIR OF A LARGE ROTATOR CUFF TEAR USING THE SUTURE BRIDGE TECHNIQUE AUGMENTED WITH PLATELET-RICH FIBRIN: A CASE REPORT

Objective To describe the arthroscopic double-row suture bridge technique for the treatment of large rotator cuff tears augmented with platelet-rich fibrin (PRF). Background Large rotator cuff tears are associated with a high retear rate because of poor tendon quality and extensive tissue defects. Platelet-rich fibrin (PRF) provides a stable fibrin scaffold enriched with multiple growth factors, including transforming growth factor-beta 1 (TGF-β1), platelet-derived growth factor (PDGF), vascular endothelial growth factor (VEGF), fibroblast growth factor (FGF), insulin-like growth factor (IGF), and epidermal growth factor (EGF). These biological mediators have been shown in animal studies to accelerate tendon-to-bone healing. Surgical Technique This case report presents the step-by-step surgical technique, including autologous platelet-rich fibrin (PRF) preparation, arthroscopic evaluation of intra-articular pathology, preparation of the tendon-to-bone footprint, anchor placement, application of PRF at the tendon–bone interface, and rotator cuff repair using the suture bridge technique. Clinical Significance The addition of PRF during arthroscopic repair of large rotator cuff tears may provide a favorable biological environment, promote early angiogenesis, and enhance tendon-to-bone healing during the early postoperative period.
