What is Viscosupplementation?
Viscosupplementation refers to injecting a hyaluronan preparation into the joint. Hyaluronan is a natural substance present in the joint fluid that assists in lubrication and allows the smooth movement of the cartilage-covered articulating surfaces of the joint.
Indications of Viscosupplementation
Viscosupplementation is indicated in the management of knee and hip 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 hyaluronan preparation is injected directly into the joint to replenish the diminished synovial fluid and enhance its lubricating properties. A single dose or three separate doses over several weeks may be required for optimum benefit.
How does Viscosupplementation Work?
The injected preparation supplements the hyaluronan in the joint and stimulates the production of new hyaluronan. You will experience gradual symptomatic relief over the course of the injections, which can last several months.
Post-procedural Care Following Viscosupplementation
If necessary, ice packs and an analgesic may be used to ease any discomfort experienced after the injection. Any strenuous activity, such as jogging or sports, should be completely avoided for 48 hours to a week after the injection and should be resumed only after consultation with your doctor.
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 a fever or the pain and swelling fail to resolve after 48 hours following the injection.
