Rotator cuff repair augmented with endogenous fibrin clot.

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.
