If you're one of the estimated 27 million Americans with osteoarthritis, you're probably all too familiar with the feeling of aching, swollen, or stiff knees.
Nonsteroidal anti-inflammatory drugs such as ibuprofen may relieve those painful symptoms in most patients. But for others, doctors may prescribe a more invasive treatment that involves injecting hyaluronic acid in to the knee, called viscosupplementation.
Now, a new report questions the efficacy of this treatment for osteoarthritis in the knee.
Hyaluronic acid is a lubricating fluid that is naturally found in the knee, but degenerates over time in people with osteoarthritis. The effect of the injection used in viscosupplementation is to stimulate cells in the knee to increase production of hyaluronic acid.

More than one in five adults in the U.S. have arthritis or other joint-damaging conditions, and the ongoing obesity epidemic may be partly to blame, according to a report issued Thursday by the Centers for Disease Control and Prevention (CDC).
Roughly 50 million U.S. adults have some form of arthritis, the report estimates.
