Rheumatoid Arthritis vs Osteoarthritis | What's the difference? - Bradford S. Waddell, MD

Dr. Bradford S. Waddell explains the key differences between rheumatoid arthritis (RA) and osteoarthritis (OA), two common forms of arthritis with distinct causes and treatment approaches. Osteoarthritis, described as the "wear and tear" type, results from the breakdown of joint cartilage due to overuse, age, or injury, and has a genetic component that predisposes individuals to joint degeneration. On the other hand, rheumatoid arthritis is an autoimmune disorder where the body's immune system mistakenly attacks its own tissues, causing inflammation and joint damage. Unlike OA, RA is associated with a specific genetic defect that predisposes individuals to develop this inflammatory arthritis.
