When do doctors remove fluid from the knee?

ANSWER

The knee and all bursae of the knee are filled with fluid. If your symptoms suggest infection or crystalline arthritis, such as gout, your doctor may remove fluid, with a needle, from your knee. A lab will test that fluid for a clearer diagnosis. A microscope can often see crystals, which suggest crystalline arthritis, in the fluid. And a microscope may also flag infection by finding bacteria and pus in the fluid.
