What areas of the body are commonly affected by rheumatoid arthritis (RA)?

Rheumatoid arthritis (RA) typically affects your body in many different ways. Most commonly joints are impacted. The areas in a joint that can be damaged are:

  • Synovium -a thin, delicate lining in joints that helps synthesize lubricants and collagens that form the structural framework of the joint. A normal synovial lining is 1 - 3 cells thick. In RA joints, this lining grows abnormally thick (also referred to as hypertrophied) to 8 - 10 cells, contributing to bone and cartilage erosion.
  • Cartilage - normally a very strong tissue, RA damages cartilage the make-up of cartilage allowing the inflammation to reach bone.
  • Bone - due to inflammation and loss of cartilage, erosion of bone in the joints is common among people with RA.
  • Synovial Cavity - in RA the area around the joint may hold large collections of fluid (known as effusions).
