Arthritis is inflammation of one or more of your joints that causes pain and stiffness. Some of these include osteoarthritis, rheumatoid arthritis, post-traumatic arthritis, septic arthritis, and psoriatic arthritis. While each of these conditions have different causes, the symptoms and treatment are often the same. Pain, swelling, and stiffness are the primary symptoms of arthritis. Any joint in the body may be affected by the disease, but it is particularly common in weight-bearing joints such as the knee, hip, and spine. Although there is no cure for arthritis, there are many treatment options available to help manage pain and keep people staying active.

Arthritis may be caused by wear and tear on the articular cartilage through the natural aging process (osteoarthritis), or may develop following an injury (post-traumatic arthritis). Other types of arthritis, such as crystalline arthritis, may come from an inflammatory process. Still others, such as rheumatoid arthritis or lupus arthritis, are the result of a systemic disease throughout the body.
