What happens during the test?
You will receive either a local or general anesthesia for this procedure. General anesthesia will put you completely to sleep and is given through an intravenous (I.V.) needle. Local anesthesia numbs the specific area for the test but you will still be awake. After the anesthetic is given, you will not feel any pain during the procedure, although with local anesthesia you may still feel pressure.
You will be asked to remove your clothes and accessories and dress in a hospital gown. The skin around your joint may need to be shaved.
The doctor places a band around the area to restrict blood flow to the joint before disinfecting the area. The surgeon makes a small incision in the skin around the joint and inserts the arthroscope. The camera on the arthroscope displays the image of the joint on the video screen making it possible for the doctor to identify and repair problems, or to take samples. Bending and moving the joint to various positions may be necessary throughout the test.
The doctor will irrigate the joint with solution throughout the procedure to clean out the joint. The incision will be stitched and covered with sterile bandages. You may need to use crutches, a sling, or a splint to help the affected area heal.
How should I prepare for this test?
Your doctor needs to know if you:
- are or may be pregnant
- are taking any medications, and what they are
- are allergic to any medications
- are allergic to anesthesia
- have an infection near the affected area
Since you will be receiving an anesthetic and possibly pain medications, arrange for someone to drive you home after the procedure.
Do not eat for 8 hours before the procedure. You may continue to drink clear liquids until 2 hours before the procedure. If your doctor has recommended different times, follow the timing recommended by your doctor.
Tell your doctor or prescriber about all prescription, over-the-counter (non-prescription), and herbal medications that you are taking. Also tell them about any medication allergies and medical conditions that you may have.
Ask your doctor or pharmacist whether you need to stop taking any of your medications before the test.
What can I expect after the test?
After the test you may experience:
- pain
- swelling for several days
- bruising
- tenderness of the area
To prevent infection, it is important to keep your bandages clean and dry. Take pain medication and apply ice as instructed by your doctor.
