All about Osteoarthritis

The breakdown of cartilage causes the bones to rub against each other, causing stiffness, pain and loss of movement in the joint. Learn more.

Rheumatoid arthritis (rue-ma-TOYD arth-write-tis) is a chronic disease, mainly characterized by inflammation of the lining, or synovium, of the joints. It can lead to long-term joint damage, resulting in chronic pain, loss of function and disability. Learn more.
