What is Viscosupplementation?
Viscosupplementation refers to the injection of a hyaluronic acid into the joint. Hyaluronan is a natural substance present in the joint fluid that assists in lubrication. It allows the smooth movement of the cartilage-covered articulating surfaces of the joint. Think of it like oil, or WD40, for the knee.
Indications of Viscosupplementation
Viscosupplementation is indicated in the management of knee osteoarthritis that has not responded to non-surgical treatment options such as pain medications, physical therapy, and corticosteroid injections. It provides symptomatic relief and delays the need for surgery.
Viscosupplementation Procedure
The hyaluranon preparation is injected directly into the joint to replenish the diminished synovial fluid, thereby enhancing its lubricating properties.
How does Viscosupplementation Work?
The injected preparation not only supplements the hyaluronan in the joint but also stimulates the production of new hyaluronan. You will experience gradual symptomatic relief over the course of the injections which can last for several months.
Post-procedural Care Following Viscosupplementation
Ice packs and an analgesic may be used, if required, to ease any discomfort experienced after the injection. Any strenuous activity such as jogging or sports should be avoided for 48 hours after the injection. Response to the injection can take several weeks, up to a month, to be apparent.
Risks and Complications of Viscosupplementation
You may experience mild pain, swelling, warmth, and redness at the injection site for up to 48 hours following the procedure. Headache and joint stiffness may also occur in some cases.
Immediately consult your doctor if you develop fever, or the pain and swelling fail to resolve after 48 hours following the injection.
