Osteoarthritis (OA) is the most common form of arthritis, affecting millions worldwide. It is a degenerative joint condition that results from the gradual breakdown of cartilage, the flexible tissue that cushions the ends of bones in your joints.

Blood tests and joint fluid analysis can help rule out other forms of arthritis, such as rheumatoid arthritis.
