Visco-Supplementation for Arthritis of the Knee

This nonsurgical procedure is an injection of a gel-like medication into the knee joint to supplement or replace the thick synovial fluid that cushions the joint. This treatment can help reduce the pain of arthritis.

The physician cleans and sterilizes the knee and injects a medication to numb the skin.

The Injection

The physician carefully guides a needle into the joint space. In some cases, a fluoroscope may be used to confirm the needle’s position. Once the tip is inside the joint, the medication is injected. The injected fluid will cushion and lubricate the knee.

End of Procedure and Aftercare

The needle is removed, and a small bandage is applied. A series of three to five injections may be required on a weekly basis. Pain relief may require multiple treatments to occur.
