Osteoarthritis is a painful degenerative condition that can affect the knee joints. In its early stages, the symptoms may be mild and can normally be managed without surgery. However, as the condition develops, symptoms worsen and more invasive treatment options may become necessary, including surgery.
Around 8.75 million people in the UK are being treated for osteoarthritis, at a cost to the health service of around £5.2 billion. One in five people over the age of 45 has osteoarthritis of the knee and 68% of people with osteoarthritis say they experience depression when the pain is at its worst.
