How It Is Done
You will be asked to remove any jewelry and to wear a hospital gown. You may be given a sedative shortly before the procedure to help you relax. The skin around your joint may be shaved.
During the procedure
If general or regional anesthesia is used, an anesthesia specialist will give the medicine. A general anesthetic will make you sleep during the procedure. Your heart rate and rhythm, blood pressure, and breathing will be watched closely during the procedure. If a local anesthetic is used, it will be injected into the skin and joint space. If a local or regional anesthetic is used, your limb will be numb. You will be relaxed and drowsy but will be awake.
You probably will lie on your back. Depending on which joint is being looked at, an inflatable band (tourniquet) may be used to briefly restrict blood flow to your joint. This allows your doctor to see all the parts inside your joint. Your joint is scrubbed with an antiseptic solution and draped with sterile towels. Before the tourniquet is inflated, the joint will be raised. It may also be wrapped with an elastic bandage to reduce blood flow to the joint.
A small incision about 0.25 in. (0.6 cm) will be made near your joint. Before the doctor inserts the arthroscope, an irrigation fluid (usually saline) will be used to flush the joint space. This gives the doctor a better view of the entire joint. A steady low flow of fluid is usually used during the procedure. This clears out any debris or blood in the joint so your doctor can evaluate your joint.
After the scope is put in, your doctor will be able to see inside the joint by viewing a video screen attached to the scope. Your doctor or the surgical assistants may bend, extend, and change the position of the joint to see it from different angles. Videotapes or photos of the joint may also be taken.
If more surgery is needed to repair your joint problem, more small incisions will be made. Other thin tools will be put into your joint. When the arthroscope and any other tools are taken out, any blood and debris will be flushed with saline and drained. To reduce swelling or pain, local anesthetics or corticosteroids may be injected into your joint.
The small incision is closed with stitches, skin glue, or tape strips. Depending on which joint was looked at, you may need to use splints, slings, or crutches while you recover from surgery.
How long the test takes
How long the procedure takes depends on what is done. It may take an hour or longer.
