For knee pain and shoulder pain secondary to loss of cartilage and osteoarthritis, injection of Hyaluronan (high molecular weight hyaluronic acid) can reverse symptoms and provide relief from pain and avoid more invasive procedures including surgical repair, revision, and replacement. ORTHOVISC® is a viscosupplement injection. Made from a natural substance that lubricates and cushions your joint, it can provide up to six months of osteoarthritis knee or shoulder pain relief with just one injection. Because it is not made from animals, the likelihood of any adverse reaction to its use is unlikely. It can be and often is combined with PRPT (“Platelet-Rich Plasma Therapy”) to garner even better results.
