Arthritis refers to inflammation of a joint. The inflammation may cause pain, swelling, and stiffness.
The joint inflammation of arthritis can occur for many reasons. Often the lining of the joint, the synovium, becomes inflamed. It reacts by making extra synovial fluid. This causes the joint to become swollen. The smooth white surface of the joint, the hyaline cartilage, can become thin, worn, and rough. Any joint in the body can be affected by some form of arthritis.
There are many types of arthritis, with a host of different causes, such as:
Some of the risk factors for arthritis are as follows:
Symptoms vary according to the type of arthritis and how severe it is. However, common symptoms include the following:
Diagnosis of arthritis starts with a medical history and physical examination. Joint X-rays may be normal at first, perhaps showing some swelling. Later the X-rays may show narrowing of the joint space, roughness of the joint surface, or poor alignment of the joint. Bone spurs, which are calcium deposits at the edge of the joint, may also be seen.
Blood tests, including a complete blood count, or CBC, can help detect some types of arthritis. Joint aspiration, which means removing joint fluid with a needle under local anesthesia, can sometimes provide useful information. Rarely, a magnetic resonance imaging, or MRI, is needed to determine the cause or extent of the arthritis.
Following sports safety guidelines for children, adolescents, and adults may help prevent some joint damage. Injuries and infections should be treated promptly. For example, a severe ankle sprain that is not properly splinted may lead to osteoarthritis. Untreated Neisseria gonorrhoeae\ bacteria. These infections are usually acquired through sexual contact. A gonococcal infection may also be passed from mother to baby during childbirth. ',CAPTION,'Gonococcal Infections');" onmouseout="return nd();">gonococcal infections may lead to infectious arthritis.
If the arthritis progresses, joint function may keep declining. The person will have more joint pain, stiffness, and swelling. The amount and rate of decline depend on the type of arthritis and how well the available treatments work.
Arthritis is not contagious. It poses no risk to others. If the arthritis is caused by an infection, such as gonorrhea, the infection may be contagious.
Treatment varies quite a bit, depending on the type of arthritis and its severity. The age, health, and activity level of the person also are factors to consider. Education about the disease can help bring about improved daily self-management and coping skills.
Nonsteroidal anti-inflammatory drugs, or NSAIDs, such as ibuprofen and aspirin, are often used to treat early symptoms of arthritis. COX-2 specific inhibitors, such as rofecoxib or celecoxib, can also help to relieve symptoms. For some forms of arthritis, corticosteroids such as prednisone can work very well. Corticosteroids can be taken by mouth or injected into the joint. Depression and sleep disorders may be treated with low doses of antidepressant medicines, such as amitriptyline.
A wide variety of medicines are used to treat rheumatoid arthritis:
If there is a bacterial infection of the joint, antibiotics are critical. The joint may be drained by repeated aspiration or by open surgical drainage.
A change in diet may help some forms of arthritis. People who have arthritis might experience loss of appetite or anemia, which is a low red blood cell count. Frequent small feedings or protein supplements may be prescribed. Some medicines, such as oral corticosteroids, can stimulate the appetite and lead to weight gain. Losing excess weight can help, especially when the leg joints are affected. Foods high in protein, iron, and vitamins contribute to tissue building and repair.
Physical activity is important in the treatment of arthritis. Thirty minutes of moderate exercise a day can help to prevent complications of arthritis, as well as heart disease, stroke, and diabetes. Low impact aerobics and water aerobics are two exercises that minimize joint stress.
A recent study focused on adults with osteoarthritis who used tai chi, a form of Chinese exercise that uses slow, fluid movements. Study participants reported better management of their symptoms, along with improved physical and mental health.
Surgery may be indicated when pain cannot be controlled or function is lost. Several types of surgery may be done:
There has been a great deal of interest lately in the use of glucosamine and chondroitin. These dietary supplements may decrease joint pain associated with arthritis. A large scale study is currently being conducted to determine their effectiveness.
Medicines used to treat arthritis may cause stomach upset, allergic reaction, and decreased resistance to infection. Surgery may cause bleeding, infection, or allergic reaction to anesthesia.
Most types of arthritis require lifelong treatment. Exercises to maintain range of motion and muscle strength are very important.
A healthcare provider will monitor the person's level of comfort and function of the joint. Any new or worsening symptoms should be reported to the healthcare provider.
