Which type of arthritis is known as “wear and tear” arthritis?

• A. Osteoarthritis
• B. Rheumatoid Arthritis
• C. Gout
• D. Juvenile Arthritis

Answer: (A)

Osteoarthritis is known as "wear and tear" arthritis because it develops due to the progressive degeneration of joint cartilage and underlying bone, primarily resulting from the natural aging process and mechanical stress on the joints over time. This condition often emerges in weight-bearing joints such as the knees, hips, and spine, where the cartilage that cushions the ends of bones gradually wears away. As this cartilage deteriorates, the bones can rub against each other, leading to pain, stiffness, and reduced mobility, which are characteristic symptoms of osteoarthritis.

In contrast, rheumatoid arthritis is an autoimmune disorder characterized by inflammation of the synovial membrane, leading to joint damage and pain. Gout is a type of inflammatory arthritis caused by the accumulation of uric acid crystals in the joints, and juvenile arthritis is an umbrella term for several types of arthritis that affect children. These conditions are distinct from osteoarthritis's wear-and-tear mechanism, further emphasizing why osteoarthritis is specifically referred to as "wear and tear" arthritis.
