Biomechanical Analysis of Rotator Cuff Repairs With Extracellular Matrix Graft Augmentation

Abstract

Despite advances in surgical techniques, 20% to 90% of rotator cuff (RTC) repairs fail. They tend to fail at the suture-tendon junction due to tension at the repair and gap formation prior to healing. This study evaluated the gap formation and ultimate tensile failure loads of a RTC repair with a decellularized human dermal allograft. Augmentation of a RTC repair with an extracellular matrix graft decreased gap formation and increased load to failure in a human RTC repair model. [Orthopedics.2014; 37(9):608–614.]…
