Types of Arthritis

There are more than 100 types of arthritis and related joint conditions such as gout. But the most common types are osteoarthritis (OA) and rheumatoid arthritis (RA). Here are some of the differences:

Osteoarthritis (OA)

  • A joint condition that causes pain and loss of movement, along with loss of cartilage and degradation of cushioning fluid in the joint
  • Mostly affects people over 40
  • The most common joint condition worldwide. Affects 21 million Americans
  • Often takes a long time to develop
  • Affects a few joints, including knees, hips, hands and spine
  • Minimal joint warmth, redness and swelling. Morning stiffness, if any, usually lasts 20 minutes or less
  • No general symptoms, such as fatigue or fever

Rheumatoid Arthritis (RA)

  • A systemic, autoimmune disease which causes the joint lining to become inflamed
  • Usually starts between the ages of 25 and 50
  • Affects 2.1 million people in the U.S., mostly women
  • May develop within weeks or months
  • Affects many joints, including wrists, knees, hips, hands and spine
  • Causes warmth, redness and swelling. Prolonged morning stiffness, lasting for hours
  • Can cause general feeling of sickness, fatigue and weight loss

Synvisc-One® (hylan G-F 20) and SYNVISC® (hylan G-F 20) are indicated for the treatment of pain in osteoarthritis (OA) of the knee in patients who have failed to respond adequately to conservative non-pharmacologic therapy and simple analgesics, e.g., acetaminophen.


Important Safety Information

Before trying Synvisc-One or SYNVISC, tell your doctor if you are allergic to products from birds—such as feathers, eggs or poultry—or if your leg is swollen or infected. Synvisc-One and SYNVISC are only for injection into the knee, performed by a doctor or other qualified health care professional. Synvisc-One and SYNVISC have not been tested to show pain relief in joints other than the knee. Talk to your doctor before resuming strenuous weight-bearing activities after treatment. Synvisc-One and SYNVISC have not been tested in children, pregnant women or women who are nursing. You should tell your doctor if you think you are pregnant or if you are nursing a child. The side effects most commonly seen when Synvisc-One or SYNVISC is injected into the knee were pain, swelling and/or fluid buildup in or around the knee. Cases where the swelling is extensive or painful should be discussed with your doctor. Allergic reactions such as rash and hives have been reported rarely.
