Osteoarthritis (OA) is the most common chronic (long-lasting) joint condition. A joint is where two bones come together. The ends of these bones are covered with protective tissue called cartilage. With OA, this cartilage breaks down, causing the bones within the joint to rub together.OA occurs most often in older people, although it can occur in adults of any age. OA is also called degenerative joint disease, degenerative arthritis, and wear-and-tear arthritis. Osteoarthritis can be caused by aging, heredity, and injury from trauma or disease.OA is caused by joint damage. This damage can accumulate over time, which is why age is one of the main causes of the joint damage leading to osteoarthritis. The older you are, the more wear and tear you’ve had on your joints.
