ABOUT OSTEOARTHRITIS

That begs the question: Will replacing hyaluronic acid relieve osteoarthritis symptoms?
Hyaluronic acid injections (also known as viscosupplements) are approved by the U.S. Food and Drug Administration (FDA) for treating osteoarthritis of the knee, though some doctors have used the therapy on other joints, such as the hip and ankle.
While studies of hyaluronic acid injections have occasionally yielded disappointing results, many doctors who treat osteoarthritis say that the weight of scientific evidence – and their own clinical experience – suggests that a shot in the knee can produce significant relief for some patients.
Furthermore, lab and clinical research hints that hyaluronic acid may do much more than simply re-grease a creaky joint.
