What is the difference between rheumatoid arthritis and osteoarthritis?

  • Rheumatoid arthritis (RA) is an autoimmune disease where the immune system attacks the joints, leading to inflammation, pain, and damage to the joint lining. It commonly affects joints on both sides of the body.
  • Osteoarthritis (OA) is a degenerative joint disease caused by the breakdown of cartilage over time, leading to pain, stiffness, and reduced mobility. OA usually affects weight-bearing joints like the knees, hips, and spine.
