Joint Aspiration (Arthrocentesis)
About the procedure
Joint aspiration, or arthrocentesis, involves removing fluid from a joint using a sterile needle. It helps diagnose the cause of joint swelling, pain, or inflammation and can relieve pressure or discomfort. The fluid may be analyzed for infection, crystals (gout), or autoimmune conditions.
Care before the procedure
- Inform your doctor about medications, especially blood thinners or anti-inflammatory drugs.
- Avoid topical creams or ointments on the joint before the procedure.
- Wear loose clothing for easy access to the joint.
- Allergies or previous reactions to local anesthesia should be reported.
Care during the procedure
- The joint area is cleaned with antiseptic and local anesthesia is applied.
- A sterile needle is inserted to withdraw fluid from the joint.
- Fluid may be sent to the lab for analysis.
- The procedure usually takes a few minutes and is generally well tolerated.
Care after the procedure
- Apply pressure and a small dressing to prevent bleeding.
- Rest the joint and avoid strenuous activity for 24 hours.
- Mild pain or swelling may occur; use prescribed medications if needed.
- Report redness, warmth, increased swelling, or fever immediately.
- Follow-up may include review of lab results and further treatment.
Eligibility
- Patients with swollen, painful, or stiff joints.
- Suspected joint infections (septic arthritis).
- Individuals with gout or pseudogout to identify crystal deposits.
