How Do Viscosupplement Treatments work?

Intra-articular injection of Hyaluronic Acid, or viscosupplementation, consists of an injection of exogenous Hyaluronic Acid into the joint.

Hyaluronic acid is the most important component of the synovial fluid and acts as a joint lubricant and shock absorber. Synovial fluid is found in the joint space and protects the cartilage and bone. The injected Hyaluronic Acid replenishes the synovial fluid and replaces modified Hyaluronic Acid, helping to lubricate the joint and ease symptoms.

Medical diagnosis

If you are experiencing symptoms such as joint pain, stiffness and swelling, talk to your doctor about whether you have osteoarthritis.

During the physical examination your doctor will look for a number of things such as tenderness, swelling or redness, creaking and swelling, and for the range of motion in the joint. Your doctor may order imaging tests such as x-rays or magnetic resonance imaging (MRI) to obtain pictures of the affected joint. Osteoarthritis can vary in intensity, ranging from mild to moderate to severe.
There are several different treatment options that depend on which joint is affected, the symptoms and their severity. Your doctor will talk with you to work out a plan that is right for you.
