Understanding synovial cell diversity in post-traumatic OA

Research related to the role of the synovium and its cell constituents during the pathogenies of osteoarthritis (OA) has taken a back seat to that of the cartilage and chondrocytes. The influence of synoviocytes in OA is increasingly recognized, but are synoviocytes equal in their contributions to disease progression?
