Osteoarthritis is the most common joint disease, affecting more than 3 million Australians and over 500 million people worldwide.
The knee is the most commonly affected joint, but osteoarthritis can also affect other joints including the hips and hands. The condition causes painful and stiff joints.
For someone with knee osteoarthritis, simple activities that many people take for granted such as walking, going up and down stairs or squatting can be very challenging.
