Arthritis is inflammation or degeneration of one or more joints. A joint is the area where 2 bones meet. There are more than 100 different types of arthritis.
Joint inflammation; Joint degeneration
Arthritis involves the breakdown of cartilage. Normal cartilage protects a joint and allows it to move smoothly. Cartilage also absorbs shock when pressure is placed on the joint, such as when you walk. Without the normal amount of cartilage, the bones under the cartilage become damaged and rub together. This causes swelling (inflammation), and stiffness.
Joint inflammation and damage may result from:
In most cases, the joint inflammation goes away after the cause goes away or is treated. Sometimes, it does not. When this happens, you have long-term (chronic) arthritis.
Arthritis may occur in men or women. Osteoarthritis is the most common type.
Other, more common types of inflammatory arthritis include:
Arthritis causes joint pain, swelling, stiffness, and limited movement. Symptoms can include:
Exams and Tests
The health care provider will perform a physical exam and ask about your medical history.
The physical exam may show:
Some types of arthritis may cause joint deformity. This may be a sign of severe, untreated rheumatoid arthritis.
Blood tests and joint x-rays are often done to check for infection and other causes of arthritis.
The provider may also remove a sample of joint fluid with a needle and send it to a lab to be checked for inflammation crystals or infection.
The goal of treatment is to reduce pain, improve function, and prevent further joint damage. The underlying cause often cannot be cured.
Lifestyle changes are the preferred treatment for osteoarthritis and other types of joint swelling. Exercise can help relieve stiffness, reduce pain and fatigue, and improve muscle and bone strength. Your health care team can help you design an exercise program that is best for you.
Exercise programs may include:
Your provider may suggest physical therapy. This might include:
Other things you can do include:
Medicines may be prescribed along with lifestyle changes. All medicines have some risks. You should be closely followed by a doctor when taking arthritis medicines.
It is very important to take your medicines as directed by your provider. If you are having problems doing so (for example, because of side effects), you should talk to your provider. Also make sure your provider knows about your all the medicines you are taking, including vitamins and supplements bought without a prescription.
SURGERY AND OTHER TREATMENTS
In some cases, surgery may be done if other treatments have not worked. This may include:
A few arthritis-related disorders can be completely cured with proper treatment.
Most forms of arthritis however are long-term (chronic) conditions.
Complications of arthritis include:
When to Contact a Medical Professional
Call your provider if:
Early diagnosis and treatment can help prevent joint damage. If you have a family history of arthritis, tell your provider, even if you do not have joint pain.
Avoiding excessive, repeated motions may help protect you against osteoarthritis.
