Augmentation of rotator cuff repair with gelatin-resorcin-formalin glue: a biomechanical study.

Introduction: Rotator cuff tendons are typically reattached to the proximal humerus using transosseous sutures or suture anchors. Their primary mode of failure is at the tendon-bone interface.

Methods: We investigated the addition of an adhesive, gelatin-resorcin-formalin (GRF) glue, to a single-row rotator cuff repair (RCR) on ex vivo sheep models.
