What is Osteoarthritis
Osteoarthritis (OA) is a form of arthritis where joint cartilage breaks down. It is the most common form of arthritis. It most commonly occurs in adults aged over 45 but it can present itself in much younger adults and even in children.
Sometimes OA develops as a result of something that can be identified: maybe a pre-existing medical condition, an abnormality or an injury. But this isn’t always the case; it can just ‘happen’ without an obvious cause.
