What Is Joint Aspiration?

Tuesday, 29 April 2014 11:48 PM

Joint aspiration is a procedure that is conducted on patients. The procedure may either require hospitalization or it can be done in a hospital setting. An injection is used as an anesthetic. A needle is used to remove the fluid out of the knee of the patient. Joint aspiration is commonly known as arthrocentesis.
Joint aspiration is usually done on patients who are suffering from arthritis. Arthritis causes pain and difficulty in the movement of the joints. Since the patient goes through a lot of pain in the knee, the fluid developed needs to be checked in the laboratory. Analysis of this fluid can help determine the cause of the arthritis, such as rheumatoid disease, gout, or infection.

To determine the cause of infection, white cell count, glucose, and protein are tested in this fluid. The kind of arthritis is determined with this analysis of the fluid.
Joint aspiration is also used to relieve the patient from pain and swelling in the knee. The removal of the knee fluid also removes white blood cells that are enzymes, which results in the destruction of the knee joint.

How Is Joint Aspiration Performed?

Joint aspiration requires the knee to first get cleaned using Betadine. A local anesthetic is given in the form of an injection. A needle is used to remove fluid from the knee of the patient. Under some conditions, doctors may insert medicated injections into the knee. After the needle is removed, the area is dressed to cover the entry point.

What Are the Benefits Derived?

Joint aspiration helps in decreasing the fluid accumulation in the joints. It may offer temporary relief from pain and stiffness. Joint aspiration helps in treating inflammatory joint conditions such as gout, rheumatoid arthritis, psoriatic arthritis, etc.

What Are the Possible Complications?

Patients usually do not face any complications due to the joint aspiration procedure. In rare cases, some may show a reaction due to the local anesthetic. There could be minor bleeding into the joint or some minor bruising in the area. The serious complication that could arise is infection of the joint.
If corticosteroids are used in the injection, it can give rise to uncommon complications. In this case, the complications can be painful for the patient to endure.
The fluid buildup in the knee is a major cause of pain. This fluid leads to inflammation of joints and also gives rise to redness and swelling. All this adds to the pain. Joint aspiration helps to assess the nature of the fluid and helps the patient combat this pain.
