What is osteoarthritis?
Osteoarthritis is a disease that causes the breakdown of the
cartilage in joints. It also called degenerative arthritis
or degenerative joint disease (DJD). Cartilage is the
joint's cushion. It covers the ends of bones and allows
free movement. If it becomes rough, frays, or wears away,
bones grind against each other. As a result, the joint
becomes irritated, inflamed, and swollen. Sometimes the
irritation causes abnormal bone growths, called spurs, which
increase swelling. The disease normally affects the feet,
knees, lower back, hips, and fingers. Usually only one or
maybe a few joints are affected at one time.
How does it occur?
The exact cause of osteoarthritis is not known, but
excessive wear on joints is known to be an important factor.
Osteoarthritis is caused by excessive wear on joints.
Obesity, bad posture, old injuries, and overuse can all
cause extra wear on joints. Heredity also appears to play a
role.
Osteoarthritis is more common in women than in men.
What are the symptoms?
Because wear and tear on the joints helps osteoarthritis
develop, the joints start to be affected by early adulthood.
Osteoarthritis gradually gets worse as you get older.
Although there may be signs of it on X-rays of younger
people, they may not have any symptoms. Symptoms of
arthritis are usually first noticed after the age of 60.
However, they can happen earlier or later than this.
The symptoms of osteoarthritis include:
- mild to severe pain in a joint, especially after overuse
or long periods of inactivity, such as sitting for a long
time
- creaking or grating sound in the joint
- swelling, stiffness, limited movement of the joint,
especially in the mornings
- weakness in muscles around the sore joint from lack of
use
- misshapen joint.
How is it diagnosed?
Your healthcare provider will review your medical history
and examine you. You may also have blood tests and X-rays.
A sample of fluid in a painful joint may be taken with a
needle to check the diagnosis.
How is it treated?
The goal of treatment is to keep the joint working by
reducing strain on the joint and by relieving pain,
stiffness, and swelling.
Medicine can control pain and reduce inflammation. Most of
the time, acetaminophen is the best medicine to use to
relieve pain. It has fewer side effects than other pain
relievers when used for a long time.
Nonsteroidal anti-inflammatory drugs (NSAIDs) such as
aspirin, ibuprofen, and naproxen can help relieve pain and
inflammation. These NSAIDs may be bought with or without a
prescription. Adults 65 years old and older should not take
NSAIDs for more than 7 days without their healthcare
provider's approval. NSAIDs help reduce pain and swelling
but can cause kidney and stomach problems.
COX-2 inhibitors such as celecoxib (Celebrex) are
prescription NSAIDs. COX-2 drugs may cause fewer stomach
problems than other NSAIDs. COX-2 inhibitors can help
arthritis symptoms, but they have been linked to a greater
risk of heart attacks and stroke. Talk with your
healthcare provider to learn more about taking NSAIDs.
Rubbing anti-inflammatory or deep-heat creams over an
arthritic joint can provide short-term relief. Putting an
ice pack on the joint once or twice a day can also help
relieve pain. Hot paraffin baths can help symptoms in the
hands and feet.
Nutritional supplements such as glucosamine and ginger may
help relieve pain. Yoga and acupuncture may help reduce
pain and stiffness in the joints.
Your healthcare provider may inject steroids into the
painful joint to help relieve pain.
If you are overweight, your provider may recommend that you
lose weight. This may be done by eating fewer calories and
increasing your physical activity. This helps
reduce strain on the joint.
Canes, walkers and other mobility aids help take the weight
off of affected joints and reduce pain. Splints offer
protection from overuse of joints. Physical therapy helps
relieve pain and muscle spasms. It also helps you keep range
of motion. Regular gentle exercise is very important to
help you control osteoarthritis.
Sometimes severely damaged joints may be surgically
replaced.
How long will the effects last?
There is no cure for osteoarthritis. Once you are diagnosed
with it, you will have it for the rest of your life. It can
worsen over time. Avoiding repeated injury to your joints
can help, but damaged cartilage cannot repair itself.
How can I take care of myself?
No one yet knows how to prevent osteoarthritis, but you can
help reduce symptoms by following these guidelines:
- Keep your joints in good working order. Stay fit. Do any
exercises recommended by your healthcare provider or
physical therapist for posture, muscle strength, and joint
mobility. Daily moderate exercise is much better for your
joints than occasional strenuous exercise. Walk a little
each day if you can. Be sure to wear comfortable,
well-cushioned walking shoes. Otherwise, you can exercise
while sitting down or you might go swimming. The water in
a warm swimming pool can help support your weight while
you exercise, and the warmth helps joint movement.
- Protect your joints by doing warm-up and stretching
exercises before strenuous activity.
- Use a knee pad to protect your knees when you are
kneeling.
- Take the medicine your healthcare provider recommends
for controlling your osteoarthritis.
- Keep your body healthy by eating a healthy, varied,
low-fat diet.
- Follow your healthcare provider's recommendations for
weight control.
