What is ORTHOVISC?
ORTHOVISC® is a viscous (thick) sterile mixture made from highly purified hyaluronan from rooster combs. Hyaluronan is a natural chemical found in the body. High amounts of hyaluronan are found in the joint tissues and in the fluid that fills the joints. The body's own hyaluronan acts like a lubricant and a shock absorber in the joint. It is needed for the joint to work properly. When you have osteoarthritis, there may not be enough natural hyaluronan in the joint, and the quality of that hyaluronan may be poorer than normal. ORTHOVISC® is given in a shot (injection) directly into the knee joint.
What is ORTHOVISC used for?
ORTHOVISC® is used to relieve knee pain due to osteoarthritis. It is used for patients who do not get adequate pain relief from simple pain relievers like acetaminophen or from exercise and physical therapy.
What are the benefits of ORTHOVISC?
Clinical trials conducted in the U.S. have shown that ORTHOVISC® provides pain relief to patients who have not been able to find pain relief with simple pain medication or exercise compared to saline placebo injections.
