What is the most common form of arthritis?

• A. Rheumatoid Arthritis
• B. Gout
• C. Psoriatic arthritis
• D. Osteoarthritis

Answer: (D)

Osteoarthritis is the most common form of arthritis. It’s a degenerative joint disease driven by aging and repeated joint use, causing cartilage breakdown and changes in the bone. This leads to joint pain, stiffness after inactivity, and reduced range of motion, typically in weight-bearing joints like the knees, hips, and spine. Imaging often shows joint space narrowing and bone spurs. Management aims to preserve function and ease pain: maintaining a healthy weight, staying active with low-impact exercise, physical therapy, and pain relief with NSAIDs or acetaminophen; injections or interventions may be considered, and severe cases can require joint replacement. Other forms—rheumatoid arthritis, gout, and psoriatic arthritis—have distinct causes (autoimmune, crystal deposition, or psoriasis-associated) and are less common overall. The standout point is that osteoarthritis is the most prevalent arthritis.
