Thromboplastic and Fibrinolytic Activity of Human Synovial Membrane and Fibrous Capsular Tissue.

Abstract

Human synovial tissue and fibrous capsular tissue contain no or only traces of tissue thromboplastin. Both tissues contain an activator of plasminogen. Hence clot formation in joints depends upon the plasma thromboplastin. This explains the occurrence of hemorrhage into joints in hemophilic patients.
