SUMMARY
1. Initially starts with injury to synovial microvasculature.
2. Synovial proliferation occurs.
3. Leads to congestion, edema, and fibrin exudation.
4. T-lymphocytes infiltrate.
5. The synovium then hypertrophies (cartilage is destroyed).
6. Pannus formation occurs: the most important destructive element in RA. This is a membrane of granulation tissue that covers the articular cartilage at joint margins.
7. The pannus stimulates the release of cytokines, leading to cartilage destruction, bone erosion, and an inflammatory synovial fluid.
