What is Osteoarthritis (OA)?

What is Osteoarthritis?

Osteoarthritis (OA) is a disease that affects the joints. Osteoarthritis is the most common form of arthritis-about 21 million people in the United States are affected by OA. It usually begins after age 40 and is most common in people over age 65, but people in their 20s or 30s can get OA too. Overuse of the knee joint, job- or sports-related injuries, being overweight, and family history can all play a role in OA.

Learning more about osteoarthritis can help you take control of your knee pain. This section provides information about osteoarthritis, what causes it and how to treat it.

Important Safety Information for HYALGAN®

HYALGAN® is used to relieve knee pain due to osteoarthritis. It is used for patients who do not get adequate relief from simple painkillers or from exercise or physical therapy.
You should not take this product if you have had any previous allergic reaction to HYALGAN® or other medications containing hyaluronan. You should not have an injection into the knee if you have an infection or skin disease in the area of the injection site.
HYALGAN® has been used in a number of countries in Europe, South America, and Asia since 1987. During this time, two cases of serious, allergic-type events were reported right after patients received the injection.
The most common side effects of HYALGAN® therapy are injection-site pain, swelling, heat and/or redness, rash, itching, or bruising around the joint. Any such side effects are generally mild and usually do not last long.
