Arthritis and Joint Pain of the Knee :
Arthritis is the name given to a group of diseases that cause joint pain or inflammation, limit movement or otherwise harm the joints. There are many types of arthritis, including:
• Osteoarthritis, a “localized” disease that may strike one joint or many
• Rheumatoid arthritis, a body-wide disease that can attack various organs as well as multiple joints
• Gout, which often targets the large toe, causing very painful swelling
• Infectious arthritis, in which bacteria, viruses or fungi settle into a joint and trigger pain, swelling and/or stiffness
• Psoriatic arthritis, which is linked to the skin disease psoriasis
Depending on the definition used, arthritis includes up to 100 diseases that attack the joints. Some types of the disease respond well to treatment, others do not; some are self-limiting while others become progressively worse; some strike youngsters while others target people in their middle or senior years.
All forms of arthritis, however, have something in common: they cause pain, swelling, movement limitation or other problems with one or more joints.
