SUPARTZ® Joint Fluid Therapy (also called a viscosupplement) is a non-surgical, non-pharmacologic therapy for knee osteoarthritis. SUPARTZ® therapy can help relieve your pain, improve your mobility, and get you back to your normal activities.

How SUPARTZ® Works

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

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

Breaking the vicious cycle! SUPARTZ Joint Fluid Therapy treats knee osteoarthritis by providing temporary replacement for the diseased synovial fluid in your knee, which is an underlying cause of your pain. Unlike oral analgesics or non-steroidal anti-inflammatory drugs (NSAIDs) that affect all parts of your body, SUPARTZ specifically targets the osteoarthritis in your knee.

What do SUPARTZ® and roosters have in common? Hyaluronan is a natural substance found in your joint cartilage and in the synovial fluid that fills your joints. In the knee joint, hyaluronan acts like a lubricant and a cushion.

The goal of SUPARTZ® is to supplement poor-quality hyaluronan in your painful knee with additional highly purified hyaluronan. SUPARTZ® therapy is an injectable solution made from highly purified sodium hyaluronate (also known as hyaluronic acid [HA]) that is extracted from rooster combs. These are harvested from roosters that have been certified as suitable for human consumption via pre- and post-mortem veterinary inspection.

A short 3-step injection process – Your doctor will inject SUPARTZ therapy directly into your knee joint right in the office.

The whole procedure takes only a few minutes:
  1. We numb your knee with a local anesthetic
  2. We remove the fluid that is currently in your knee joint with a process called arthrocentesis, and
  3. Inject SUPARTZ® into the knee joint space

You’ll be asked to avoid strenuous activities for a couple of days following the injection. Most patients experience little or no discomfort during the injection. If you’re concerned about the injection, talk to us about ways to reduce any mild pain that may occur.
