aspiration (joint aspiration)
Joint aspiration, also known as joint tap, is a medical procedure where a healthcare provider uses a needle and syringe to remove fluid from a joint, such as the knee or shoulder. This can help diagnose the cause of joint swelling, pain, or inflammation, and may also provide relief by reducing pressure or removing infected or excess fluid. The procedure is usually quick and performed under local anesthesia, with minimal discomfort. Analyzing the removed fluid can help identify infections, gout, or other joint problems, guiding appropriate treatment.
