What is osteoarthritis (OA)?

OA is often referred to as ‘degenerative joint disease’ and usually develops slowly, over a period of years. It is a very common disease – 6% of adults aged 30 and above have frequent knee pain. Over time, the cartilage on the surface of the joint starts to get damaged and wear away and this causes pain and stiffness in the joint.18

If you suffer from arthritis you will be all too familiar with the range of symptoms that it causes and their effect upon your life.

How does DUROLANE work?

When you have osteoarthritis (OA), the hyaluronic acid (HA) in the synovial fluid in your joint becomes diluted and breaks down – reducing its natural properties.7 This is associated with increased inflammatory processes that can degrade the cartilage.7

This inflammation causes pain receptors to begin firing during normal movement.7 The pain tends to cause OA patients to limit movement which, in turn, contribute to further deterioration of joint structures and synovial fluid quality because movement is required for normal synovial activity. This process can become a vicious cycle as the disease becomes progressively worse and quality of life is severely compromised for patients.

DUROLANE is a single-injection treatment to relieve the pain of osteoarthritis in specific small and large joints.2 It is based upon a safe and proven technology of stabilised HA, NASHA®. HA is a naturally occurring molecule that provides the lubrication and cushioning in a normal joint.
