  • Lesson Rheumatoid Arthritis addresses these key points

  • Joints Affected by RA

    • RA is a systemic autoimmune disease
    • Typically affects the synovial joints of the body

    Synovial joints

    • Most flexible joints 
    • Allow the greatest range of motion
    • Most commonly affected by RA

    Synovitis and the Synovial Pannus

    • Release of cytokines that enhance inflammation
      • IL-1
      • TNF-α
      • IL-17

    Synovial Joints

    • Bones they join are separated by a fluid-filled capsule
    • Capsule made up of two layers:
      • Thick, tough outer fibrous capsule
      • Thin, inner synovial membrane, or synovium
    • Synovial fluid
      • Viscous and slippery
    • Cartilage
      • Ends of bones connected by the joint 
    • Synovial joints reinforced by ligaments

    Exercise: Normal Joint vs. Joint Affected by RA

    • Ligament
    • Fibrous capsule
    • Synovium
    • Inflamed synovium
    • Synovial fluid
    • Synovial pannus
    • Decreased joint space
    • Cartilage
    • Erosion of cartilage/bone
