Patient Education: Arthrocentesis
What is Arthrocentesis?
Arthrocentesis, also known as joint aspiration, is a medical procedure where a sterile needle and syringe are used to remove fluid from a joint space. This procedure is commonly performed to diagnose and treat various joint conditions, including arthritis, infection, and inflammation.
Purpose of Arthrocentesis:
- Diagnostic: Arthrocentesis can help identify the cause of joint symptoms by examining the characteristics of the fluid, such as color, clarity, and cell count.
- Therapeutic: Removing excess fluid from a joint can help alleviate pain, swelling, and improve joint mobility.
Procedure Overview:
During arthrocentesis:
- Your skin will be cleaned and sterilized around the joint area.
- A local anesthetic may be administered to numb the area.
- A sterile needle is inserted into the joint space under the guidance of imaging (e.g., ultrasound).
- Fluid is withdrawn into a syringe for analysis or therapeutic purposes.
- After the procedure, a bandage may be applied to the site, and you may be instructed to rest and apply ice to the area.
Risks and Complications:
Although arthrocentesis is generally safe, potential risks and complications may include:
- Infection
- Bleeding
- Joint damage
- Allergic reactions to medications
Preparation:
- Inform your healthcare provider about any allergies, medications, or medical conditions you have.
- Follow any pre-procedure instructions provided, such as fasting or discontinuing certain medications.
Aftercare:
- Rest the joint and avoid strenuous activities for a period recommended by your healthcare provider.
- Apply ice to reduce swelling and pain as needed.
- Monitor the site for signs of infection, such as increased pain, redness, or swelling.
Follow-Up:
Your healthcare provider will discuss the results of the arthrocentesis and any further treatment recommendations. Follow-up appointments may be scheduled as needed.
Questions and Concerns:
If you have any questions or concerns about the arthrocentesis procedure, its risks, benefits, or aftercare, do not hesitate to discuss them with your healthcare provider.
