Osteoarthritis (also known as OA) is the most common type of arthritis and one of the most common causes of knee pain; affecting more than 1.3 million Australians.
What happens in knees with osteoarthritis
A healthy knee has cartilage and lubricating joint fluid — called synovial fluid — to protect and cushion the bones, allowing the knee to move and bend. In knees with osteoarthritis, the cartilage protecting the ends of the bones gradually deteriorates, and the joint fluid loses its shock-absorbing qualities. Bones may begin to rub against each other, causing the common symptoms of knee osteoarthritis — pain, stiffness and loss of movement in the joint.
What can be done about osteoarthritis
Osteoarthritis is a chronic condition that typically develops slowly and gradually worsens over time. Though there is no cure for osteoarthritis, the symptoms are treatable, especially in the early stages of the disease.In addition to the diagnosis of osteoarthritis, Painsense offers two primary treatment options:
- Viscosupplementation – (also called hyaluronic acid) — a joint injection, such as Synvisc-One® (hylan G-F 20), that replaces damaged joint fluid with a substance similar to healthy joint fluid in order to reduce pain
- Corticosteroid Injection – to temporarily relieve pain and reduce any swelling
Painsense uses Synvisc-One® (hylan G-F 20) is a viscosupplement injection. Made from a natural substance that lubricates and cushions your joint, it can provide up to twelve months of osteoarthritis pain relief with just one injection. – Link Synvisc Patient Guide
Who is a candidate for Synvisc-One
Patients with knee osteoarthritis who have tried dietary, exercise and over-the-counter pain medication but still have pain, should talk to their doctor to see if Synvisc-One is right for them.
How Synvisc-One is administered
Synvisc-One is a single injection. It’s a simple, procedure performed under CT Guidance that only takes a few minutes.
What you can expect following a Synvisc-One knee injection
Synvisc-One can provide up to twelve months of osteoarthritis pain relief. Everyone responds differently, but in a medical study patients experienced relief starting one month after the injection.After the injection, you can resume normal day-to-day activities, but you should avoid any strenuous activities for about 48 hours.
Corticosteroid (cortisone) is an anti-inflammatory used to treat pain associated with inflammation caused through athritis.
How is corticosteroid administered
Corticosteroid is administered either as a single or multiple injection performed under ultrasound or CT guidance with a fine needle. The corticosteroid will be mixed with a local anaesthetic to assist in reducing any pain associated with the injection. The guidance allows for improved accuracy in delivering the corticosteroid to the inflammed area.
How many treatments
As a general rule, three treatments to the same body part within a twelve month period are permitted. Treatments more frequent than this increase the risk of weakening the tissue and accelerating arthritis.
