What is hylan G-F 20 (Synvisc, Synvisc One)?
Hylan G-F 20 (Synvisc, Synvisc One) is an injectable fluid that is used to treat osteoarthritis (OA) of the knee. Osteoarthritis is a type of arthritis in which the joints of the body degenerate and become painful and stiff. Osteoarthritis is the most common form of arthritis. Almost 10 million Americans suffer from the disease. Most people with OA are those 45 years old, and women. More women have OA than men.
How does Synvisc work?
Joints contain a fluid, called synovial fluid, which acts as a lubricant and shock absorber. Patients with osteoarthritis have synovial fluid that is thinner than normal, and, therefore, it is less effective as a lubricant and shock-absorber. Synvisc is an elastic fluid that is made from a substance called hyaluronan, that is found in normal joint fluid. Hyaluronan is the key substance in joint fluid that provides the shock-absorbing quality to the fluid, and it is essential for the proper functioning of joints. When Synvisc is injected into the knee of a patient with osteoarthritis, the drug helps to restore the shock-absorbing effect of the fluid within the knee. This can reduce pain, resulting in a more active lifestyle.

Arthritis (Joint Inflammation)
Arthritis is inflammation of one or more joints. When joints are inflamed they can develop stiffness, warmth, swelling, redness and pain. There are over 100 types of arthritis, including osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis, lupus, gout, and pseudogout.
Chronic pain is pain (an unpleasant sense of discomfort) that persists or progresses over a long period of time. In contrast to acute pain that arises suddenly in response to a specific injury and is usually treatable, chronic pain persists over time and is often resistant to medical treatments.
Pain management and treatment can be simple or complex, according to its cause. There are two basic types of pain, nociceptive pain and neuropathic pain. Some causes of neuropathic pain include: complex regional pain syndrome, interstitial cystitis, and irritable bowel syndrome. There are a variety of methods to treat chronic pain, which are dependant on the type of pain experienced.
A torn meniscus (knee cartilage) may be caused by suddenly stopping, sharply twisting, or deep squatting or kneeling when lifting heavy weight. Symptoms of a meniscal tear include pain with running or walking long distances, popping when climbing stairs, a giving way sensation, locking, or swelling.
