Arthritis refers to a group of conditions affecting the body’s joints, including the bone, muscle and surrounding soft tissues. The most common symptoms are joint pain, stiffness and reduced function, which can lead to disability and reduced quality of life. Arthritis is a common condition affecting 3.5 million Australians which is about 15 per cent of the population. Osteoarthritis (OA) and rheumatoid arthritis (RA) are the two most common types. Arthritis has no cure but its symptoms can be successfully managed with exercise, weight loss, lifestyle changes and appropriate medication. When symptoms become unmanageable joint replacement surgery can be considered.
