Osteoarthritis(Degenerative Joint Disease; Arthritis, Osteo-)
by
Editorial Staff and Contributors DefinitionOsteoarthritis is the breakdown of cartilage in the joints. This is followed by chronic inflammation of the joint lining. Healthy cartilage is a cushion between the bones in a joint. Osteoarthritis usually affects the hands, feet, spine, hips, and knees. People with osteoarthritis usually have joint pain and limited movement of the affected joint.
CausesThe exact cause is unclear. Risk Factors TOPRisk factors include:
Symptoms TOPSymptoms include:
Other symptoms include loss of cartilage, bone spurs around the joint, and muscle weakness of the extremity. Diagnosis TOPYour doctor will ask about your symptoms and medical history. He or she will do a physical exam. Tests may include:
Treatment TOPThere is no treatment that stops cartilage loss or repairs damaged cartilage. The goal of treatment is to reduce joint pain and inflammation, and to improve joint function. Treatments may include: Medications
Dietary SupplementsGlucosamine and chondroitin are two commonly used supplements. But, research has shown that these are not beneficial for most people with osteoarthritis. Talk with your doctor before taking any herbs or supplements. Alternative TreatmentsSome doctors report that acupuncture has been successful in reducing the pain of osteoarthritis. However, the evidence is not consistent. While more studies are needed, balneotherapy (hot water therapy), relaxation therapy, exercise, yoga, and tai chi may be helpful. Mechanical AidsShoes with shock-absorbing soles may provide some relief while you are doing daily activities or exercising. Splints or braces help to properly align joints and distribute weight. Knee and wrist joints may benefit from elastic supports. A neck brace or corset may relieve back pain. Also, a firm mattress may help chronic back pain. Canes, crutches, walkers, and orthopedic shoes can help with advanced osteoarthritis in the lower body. Weight ReductionLosing weight can lessen the stress on joints affected by osteoarthritis. Losing five pounds can eliminate at least 15 pounds of stressful impact for each step taken. The more weight lost, the greater the benefit. Exercise and Physical TherapyStrengthening the muscles supporting an arthritic joint (particularly the knee, lower back, and neck) may decrease pain and absorb energy around the joint. For example, if you have arthritis in the knee, exercise, including strength training, can also help improve knee function. Swimming and water aerobics are good options. They do not put stress on the joint. Another option is transcutaneous electrical nerve stimulation (TENS). With TENS, you are connected to a machine. The machine sends electrical signals through the skin to nerves. This type of therapy may decrease pain in some people. Assistive DevicesIf you are having difficulty getting around due to arthritis pain, your doctor might recommend that you install handrails and grips throughout your home. These are useful in the bathroom and shower. You may need elevated seats (including toilet seats) if you're having difficulty rising after sitting. Heat and IceApplying heat (with hot water bottles or heating pads) helps joints and muscles move more easily. It can also lessen pain. Using ice packs after activity can also help. Manual TherapyIf you have knee osteoarthritis, manual therapy (including massage therapy and manipulation) may be helpful. SteroidsCorticosteroid injections to the inflamed joint may be given if other pain medicines do not work. However, repeated cortisone injections can be harmful to the cartilage. They are reserved for those with severe symptoms. SurgerySurgery can:
