Arthritis

Osteoarthritis is the most common type of arthritis, affecting an estimated 20.7 million adults in the United States. Osteoarthritis primarily affects cartilage, which is the tissue that cushions the ends of bones within the joint. Osteoarthritis occurs when cartilage begins to fray, wear, and decay.

In extreme cases, the cartilage may wear away entirely, leaving a bone-on-bone joint. Bony spurs (pointy bulges of bone) may form at the edges of the joint. Osteoarthritis can cause joint pain, reduced joint motion, loss of function, and disability. Disability results most often when the disease affects the spine and the weight-bearing joints (the knees and hips).

What are the Common Symptoms of Arthritis?

• Swelling in one or more joints
• Stiffness around the joints that lasts for at least 1 hour in the early morning
• Constant or recurring pain or tenderness in a joint
• Difficulty using or moving a joint normally
• Warmth and redness in a joint

How Are Rheumatic Diseases Diagnosed?

Diagnosing rheumatic diseases can be difficult because some symptoms and signs are common to many different diseases. A general practitioner or family doctor may be able to evaluate a patient or refer him or her to a rheumatologist: a doctor who specializes in treating arthritis and other rheumatic diseases.

The doctor will review the patient’s medical history, conduct a physical examination, and obtain laboratory tests and X rays or other imaging tests. The doctor may need to see the patient more than once to make an accurate diagnosis.

The doctor will examine all of the patient’s joints for redness, warmth, deformity, ease of movement, and tenderness. Because some forms of arthritis, such as lupus, may affect other organs, a complete physical examination including the heart, lungs, abdomen, nervous system, and eyes, ears, and throat may be necessary. The doctor may order some laboratory tests to help confirm a diagnosis. Samples of blood, urine, or synovial fluid.

What Are the Treatments?

Treatments for arthritis include rest and relaxation, exercise, proper diet, medication, and instruction about the proper use of joints and ways to conserve energy. Other treatments include the use of pain relief methods and assistive devices, such as splints or braces. In severe cases, surgery may be necessary. The doctor and the patient work together to develop a treatment plan that helps the patient maintain or improve his or her lifestyle.
