SUPARTZ FX (also called a viscosupplement) is a non-surgical, non-pharmacologic therapy for knee osteoarthritis. SUPARTZ FX therapy can help relieve your pain which improves your mobility and gets you back to your normal activities and a productive life.
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 in the knee.

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

Dr. Stiegler will inject SUPARTZ FX therapy directly into your knee joint right in the office.
The whole procedure takes only a few minutes:
1.    A local anesthetic is used to numb your knee.
2.    The doctor removes the fluid that is currently in your knee joint with a process called arthrocentesis.
3.    SUPARTZ FX is injected into the knee joint space.
You should 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 Dr. Stiegler about ways to reduce any mild pain that may occur.

SUPARTZ FX treatment is approved for 5 weekly injections, but some patients may benefit from only 3 injections.
*Some patients may experience benefit with as few as 3 injections given at weekly intervals. This has been noted in a study in which patients treated with 3 injections were evaluated for 90 days

SUPARTZ FX therapy is covered by Medicare and eligible for private plan coverage for the treatment of knee osteoarthritis. However, it may not be covered by your insurance. Each insurance carrier decides which, if any, product it will cover. Before initiating SUPARTZ FX therapy, call your insurance provider or have your doctor’s office check on your behalf. If SUPARTZ FX therapy is not covered by your health plan, talk to your doctor about your options for treatment.
