Arthritis

How common is arthritis?

Arthritis is the most common cause of disability in the U.S. About 50 million adults and 300,000 children manage some form of arthritis.

What causes arthritis?

Different types of arthritis have different causes. For instance, gout is the result of too much uric acid in your body. But for other types of arthritis, the exact cause is unknown. You may develop arthritis if you:

Have a family history of arthritis.

Have a job or play a sport that puts repeated stress on your joints.

Have certain autoimmune diseases or viral infections.

What are the risk factors for arthritis?

Some factors make you more likely to develop arthritis, including:

Age: The risk of arthritis increases as you get older.

Lifestyle: Smoking or a lack of exercise can increase your risk of arthritis.

Sex: Most types of arthritis are more common in women.

Weight: Obesity puts extra strain on your joints, which can lead to arthritis.

What are the symptoms of arthritis?

Different types of arthritis have different symptoms. They can be mild in some people and severe in others. Joint discomfort might come and go, or it could stay constant. Common symptoms include:

Pain.

Redness.

Stiffness.

Swelling.

Tenderness.

Warmth.

How is arthritis diagnosed?

If you think you may have arthritis, see your healthcare provider. The provider will ask about your symptoms and learn how joint pain affects your life. Your provider will perform a physical exam, which may include:

Assessing mobility and range of motion in your joints.

Checking for areas of tenderness or swelling around your joints.

Evaluating your overall health to determine if a different condition could be causing your symptoms.

Can imaging exams detect arthritis?

Imaging exams can help your healthcare provider get a clear picture of your bones, joints and soft tissues. An X-ray, MRI or ultrasound can reveal:

Bone fractures or dislocations that may be causing you joint pain.

Cartilage breakdown around your joints.

Muscle, ligament or tendon injuries near your joints.

Soft tissue inflammation.

Can a blood test detect arthritis?

There is no blood test that can directly detect arthritis. But if your healthcare provider suspects gout or rheumatoid arthritis, they may order blood work. It looks for uric acid or inflammatory proteins.

How is arthritis treated?

There’s no cure for arthritis, but there are treatments that can help you manage the condition. Your treatment plan will depend on the severity of the arthritis, its symptoms and your overall health.

Conservative (nonsurgical) treatments include:

Medication: Anti-inflammatory and pain medications may help relieve your arthritis symptoms. Some medications, called biologics, target your immune system’s inflammatory response. A healthcare provider may recommend biologics for your rheumatoid or psoriatic arthritis.

Physical therapy: Rehabilitation can help improve strength, range of motion and overall mobility. Therapists can teach you how to adjust your daily activities to lessen arthritic pain.

Therapeutic injections: Cortisone shots may help temporarily relieve pain and inflammation in your joints. Arthritis in certain joints, such as your knee, may improve with a treatment called viscosupplementation. It injects lubricant to help joints move smoothly.

Will I need surgery for arthritis?

Healthcare providers usually only recommend surgery for certain severe cases of arthritis. These are cases that haven’t improved with conservative treatments. Surgical options include:

Fusion: Two or more bones are permanently fused together. Fusion immobilizes a joint and reduces pain caused by movement.

Joint replacement: A damaged, arthritic joint gets replaced with an artificial joint. Joint replacement preserves joint function and movement. Examples include ankle replacement, hip replacement, knee replacement and shoulder replacement.
