Our bodies naturally produce Hyaluronic acid, a dense fluid that lubricates our joints and protects cartilage and bones. Arthritic joints typically suffer from both limited quantity or poor quality fluid.  Viscosupplementation is the injection of Hyaluronic Acid (synthetically derived from chicken comb) into the joint to provide cushioning, and lubrication and thus enables more natural and less painful mobility. Many different products may be employed, but they all function the same way, ultimately protecting the joint and alleviating pain. The American Medical Society for Sports Medicine (AMSSM) is a national organization comprised of physicians from various fields of medicine including primary care physicians, PM&R doctors, orthopedic surgeons, rheumatologists, and pain management doctors. A comprehensive review of all peer-reviewed scientific literature to date conducted by the AMSSM led to the recommendation by the AMSSM for the use of viscosupplementation on appropriate patients with knee osteoarthritis.¹
