Arthrocentesis (also called joint aspiration) is a procedure where a doctor uses a needle to take fluid out of a joint. Joints are where two bones meet. They allow our bodies to move. The hips, knees, ankles, elbows, shoulders, and knuckles are all joints.

Follow your doctor’s recommendations for activity after the procedure.
The lab results usually are back in a few days. The lab will look for germs (such as bacteria), germ-fighting cells, signs of inflammation (irritation and swelling), and other things in the joint fluid. Ask your doctor how you will get the test results.

The best way to prevent Lyme disease is to prevent tick bites. Find out more about this disease and how to keep those ticks away.
Lupus is known as an autoimmune disease in which a person’s immune system mistakenly works against the body’s own tissues.
Without bones, muscles, and joints, we couldn’t stand, walk, run, or even sit. The musculoskeletal system supports our bodies, protects our organs from injury, and enables movement.
In juvenile idiopathic arthritis (also called juvenile rheumatoid arthritis)), a person can develop swollen, warm, and painful joints. Learn more.
Lyme disease can affect the skin, joints, nervous system, and other organ systems. If Lyme disease is diagnosed quickly and treated with antibiotics, most people feel better quickly.
