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.
Genetics may play a role in developing osteoarthritis. You are more likely to develop osteoarthritis if a family member has the disease. Obesity and using a joint too much can wear out joints and increase the risk of osteoarthritis.
