What happens to cartilage in osteoarthritis?

Univ. of Nev. School of Medicine, Family Medicine

In osteoartritis, cartilage is lost. Osteoarthritis is a condition in which wear and tear on your joints over time causes degenerative changes. These changes cause a loss of cartilage. When the cartilage is totally or almost totally gone, you may get a "bone on bone" situation, which can be quite painful.

In osteoarthritis, cartilage degenerates, losing its cushioning and smooth, lubricating effects. As the amount of cartilage decreases, increasing stress is placed on other structures within the joint, such as the bones, joint capsule, ligaments, and tendons.

Affects of Osteoarthritis on the Body

The most common complications of osteoarthritis (OA) are joint pain and stiffness, which can interfere with daily activities. Osteoarthritis can affect almost any joint, but is most typical in the joints that bear weight over the years, such as the knees, hips and lower back. In most cases, OA develops slowly over time, but it can worsen rapidly in severe cases. Because it may make it hard to move around and exercise, OA can also lead to weight gain.
