Viscosupplementation is a procedure where a gel-like substance called hyaluronic acid (a component of synovial fluid), is injected into the joints to increase cushioning, lubrication and shock absorbing properties. Think of this like “WD-40 for the joints”. The result is more fluid pain free range of motion. It is indicated for the treatment of osteoarthritis of the knees in patients who have failed to respond to conservative treatments (like physical therapy, NSAIDs, or even cortisone).
Osteoarthritis reduces the amount of hyaluronic acid in the joints. The result of which causes pain, stiffness, swelling and a decreased tolerance to motion (making things like walking or exercising difficult).
This is an FDA approved medical procedure that is backed by extensive research.
