An arthrocentesis is a medical procedure that involves removing fluid from a joint with a needle.

Reasons for doing an arthrocentesis may include relieving pain or inflammation in the joint, diagnosing joint disease, or evaluating the effectiveness of a treatment.

The arthrocentesis procedure usually lasts between 15 and 30 minutes.

After an arthrocentesis, pain, swelling and/or tenderness may be experienced in the treated joint. Ice should be applied to the affected area to reduce inflammation and pain, and the joint should be kept at rest for a while.

Yes, it is normal to have some pain or discomfort after an arthrocentesis. However, if the pain is severe or persistent, or if fever, redness, or severe swelling is experienced, it is important to seek medical attention.

Recovery time after an arthrocentesis can vary depending on the severity of the underlying condition and the treatment required. Generally, a full recovery can be expected within a few weeks.

As with any medical procedure, there are risks associated with arthrocentesis. Possible risks include infection, bleeding, damage to nerves and/or surrounding tissues, and an allergic reaction to the local anesthetic.

Medical checks may be needed after an arthrocentesis, especially if fluid samples have been removed for testing. It is important to follow your doctor's instructions on aftercare and schedule any necessary follow-up.
