Hyaluronic Acid Injections (HA Injections), also known as Viscosupplementation, are a nonsurgical treatment option of osteoarthritis symptoms. Hyaluronic Acid is a naturally occurring compound that is found throughout the human body, and has been isolated and purified by manufacturers into an injectable form.
In osteoarthritis, HA chains are shortened and the viscosity of joint fluid decreases. Viscosupplementation injections work through a complex mechanism, and are thought to increase the lubrication of the arthritic joint fluid, decrease inflammation and pain, and improve function.
HA injections have been shown to decrease synovial inflammation and have been FDA approved since 1997 for the treatment of knee osteoarthritis. Improvement from the injections often last 6-12 months or longer. Viscosupplementation injections are typically covered by commercial insurance; however, we always recommend checking with your insurance provider to confirm coverage. Our office will obtain pre-certification when required.
Recent studies have also shown benefit in shoulder arthritis, but HA injections into the shoulder are not FDA approved. Our billing department can answer questions regarding cost.
