in rheumatoid arthritis ( ra ) joint inflammation is due to two processes : 1 ) the underlying inflammatory process ( uip ) characterized by a lymphoplasmacellular infiltration of the synovial tissue , as well as pannus formation , and 2 ) the detritogenic synovitis ( ds ) , a synovial response to articular wear products from cartilage and bone ( detritus ) that induces a preferentially fibrinous inflammation .
