What is Knee Arthroscopy?
KNEE ARTHROSCOPY is a procedure used to diagnose the cause of pain, swelling, tenderness, or weakness in your knee. The doctor examines your knee with an instrument called an arthroscope. An arthroscope is a tube with a light on the end that is inserted in your knee and projects an image of the inside of your knee onto a TV monitor. The arthroscope is about the diameter of a pencil.
During the procedure, the doctor will give you a general, regional, or local anesthetic. A general anesthetic will relax your muscles and make you feel as if you are in a deep sleep. Both local and regional anesthetics numb part of the body while you remain awake. All three types of anesthesia should keep you from feeling pain during the operation. The doctor will then insert the arthroscope, a tube containing a saltwater solution, and a probe instrument into the lower part of your knee. He will then inject fluid into the knee. Your doctor may find loose material in the knee, or a tear in the cartilage or ligaments. Sometimes the doctor can repair the tears and remove loose pieces of cartilage using small instruments and the arthroscope. If the problem cannot be fixed by this procedure, the doctor may recommend open knee surgery. After the procedure the doctor will close the small openings with one or two stitches or sticky tape.
