Arthrocentesis is a minimally invasive procedure used to treat problems within a joint. It is commonly performed on the jaw joint, known as the temporomandibular joint or TMJ, but it can also be used on other joints in the body. The main aim is to reduce pain and improve movement by flushing out the joint and relieving pressure.
This procedure is often recommended for people who have ongoing joint pain, stiffness, or limited movement that has not improved with more conservative treatments like medication, physiotherapy, or splints. In the case of the jaw, it is frequently used to manage temporomandibular disorders, which can cause discomfort when talking, chewing, or opening the mouth.
Arthrocentesis is usually done under local anaesthetic, sometimes with light sedation. During the procedure, the clinician inserts small needles into the joint space and uses a sterile fluid to gently wash it out. This helps remove inflammatory by products and can improve how the joint moves. In some cases, medication may also be introduced into the joint to further reduce inflammation.
Recovery is generally quick compared to more invasive surgical options. Most people can go home the same day and return to normal activities within a short period, although they may be advised to follow a soft diet and avoid putting too much strain on the joint for a little while. Mild swelling or discomfort can occur but usually settles within a few days.
The benefits of arthrocentesis include reduced pain, improved joint function, and better range of movement. It can also delay or remove the need for more complex surgery in some cases.
Overall, arthrocentesis is a safe and effective option for managing joint related conditions, particularly when simpler treatments have not provided enough relief. With proper care and follow up, many people experience noticeable improvements in comfort and function.
