Rotator Cuff Repair Augmented With Endogenous Fibrin Clot

Abstract Despite recent technical advances, rotator cuff repair continues to have a high retear rate. Recent research focused on biologic augmentation of rotator cuff repair with platelet‐rich plasma has shown mixed results, and use of an endogenous fibrin clot from either peripheral blood or bone marrow may have advantages over the use of platelet‐rich plasma. This technique describes a method to make an endogenous fibrin clot and arthroscopically apply the fibrin clot to the superior surface of the rotator cuff repair site.
