Benefits and Risks of Knee Aspiration for Joint Pain or Swelling
Knee aspiration, also known as arthrocentesis, is a medical procedure in which a doctor uses a needle to remove excess fluid from the knee joint. This procedure is often recommended for patients experiencing joint pain, stiffness, or swelling that does not improve with basic treatment.
Benefits of Knee Aspiration
Reduces Pain and Swelling
By removing the excess fluid buildup in the joint, knee aspiration can relieve pressure, reduce inflammation, and improve mobility.
Helps Diagnose Joint Conditions
The fluid collected during knee aspiration can be sent for laboratory testing to detect infections, gout, rheumatoid arthritis, or other underlying conditions causing knee swelling.
Improves Mobility
After the removal of excess fluid, many patients experience better joint movement and reduced stiffness.
Guides Targeted Treatment
The results from fluid analysis help doctors determine the most effective treatment plan, whether it’s medication, physiotherapy, or surgery.
Risks of Knee Aspiration
While knee aspiration is generally safe, there are some potential risks:
Infection
There is a small risk of introducing bacteria into the joint during the procedure, which can lead to joint infection (septic arthritis).
Bleeding or Bruising
Minor bleeding or bruising can occur at the needle insertion site, especially in patients on blood-thinning medication.
Temporary Discomfort
Some people may experience mild pain, soreness, or swelling at the procedure site for a short period.
Joint Injury
Rarely, the needle may cause minor injury to surrounding tissues or structures in the knee.
Conclusion:
Knee aspiration is a quick, minimally invasive procedure that offers both diagnostic and therapeutic benefits for people with knee swelling or pain. While there are some minor risks, these are rare when the procedure is performed by an experienced healthcare professional.
If you are experiencing persistent knee pain or swelling, consult an orthopaedic specialist to see if knee aspiration is suitable for your condition.
