What is Osteoarthritis?

Osteoarthritis is the most common type of arthritis.

Osteoarthritis is a disease where your joints slowly break down. With osteoarthritis, the cartilage (the soft tissue between the bones) breaks down. This can lead to bone damage. Scientists do not know what causes cartilage to break down. However, it can be painful and limit your ability to do regular activities.

Causes of Osteoarthritis
