types of osteoarthritis
Unlike some other types of arthritis, such as rheumatoid arthritis, osteoarthritis is less likely to involve many joints around the body or migrate from around one joint to another. Rather, it affects one or a few joints, often joints that have received extra wear. Osteoarthritis affects joints differently depending on their location in the body. It is common in joints of the fingers, feet, knees, hips, and spine.
