Arthrocentesis is a relatively simple and minimally invasive procedure whereby a sterile needle and syringe are used to drain fluid from a joint.
Local anaesthetic is injected in the area of the joint. A needle with a syringe attached is inserted within the joint and fluid is sucked back (aspirated).
Joint fluid may be sent for examination to a pathologist to determine the cause of the joint swelling, such as infection, arthritis or gout.
The procedure is limited to restoring jaw function to a previously locked jaw. While admission to a Day Surgery facility is sometimes necessary, the procedure can be performed in our Consulting Rooms
