    Arthroscopy is a surgery done to examine a joint visually. Most of the time, it is done on large joints like the knee or shoulder. A special tool called an arthroscope is used. It is an instrument that looks like a long tube with a miniature camera on the end. Repairs or corrections to the joint may be done by using the arthroscope and other tools.

    Reasons for Procedure

    Arthroscopy is used to see, diagnose, and treat problems inside your joint. The procedure is most often performed for the following reasons:
    • Diagnose an injury or disease inside a joint
    • Remove bone or cartilage
    • Repair tendons or ligaments

    Possible Complications

    Problems from the procedure are rare, but all procedures have some risk. Your doctor will review potential problems, like:
    • Infection
    • Blood clots
    • Swelling or bleeding
    • Damage to blood vessels, nerves, or other tissue
    • The need to have another surgery or more extensive surgery
    Factors that may increase the risk of complications include:

    What to Expect

    Prior to Procedure

      Your doctor will likely do the following to evaluate the joint:
    • Arrange for a ride to and from the procedure.
    • Do not eat or drink anything after midnight the night before the procedure.
    • You may be asked to use a special soap the morning of the procedure.


    The type of anesthesia will depend on the joint your doctor is looking at. You may receive one of the following:
    • General anesthesia —you will be asleep
    • Local anesthesia—the area will be numbed
    • Spinal anesthetic —your lower body will be numbed by putting a numbing medication in your back

    Description of the Procedure

    Tiny incisions will be made in the skin along the joint. Special tools will be inserted through the incisions. The tools include the arthroscope. The picture from the arthroscope will show up on a screen so that the inside of your joint can be viewed. The images may be used to move around other tools that can cut and repair tissue in your joint.
    For example:
    • Some meniscal tears in the knee will be repaired by cutting and removing some of the cartilage.
    • Carpal tunnel syndrome in the wrist may be treated by loosening the ligament that puts pressure on the nerves.
    When the examination or surgery is done, the tools will be removed. The skin may be closed with stitches or clips. The incisions will be covered with a dressing. The fluid or tissue that was removed may be sent to a lab for examination.

    How Long Will It Take?

    Usually less than 1 hour, but this may be longer if repairs are being done.

    Will It Hurt?

    Anesthesia will prevent pain during surgery. Pain and discomfort after the procedure can be managed with medications.

    Post-procedure Care

    The dressings can sometimes be removed as early as the next morning. When you return home after the procedure, do the following to help ensure a smooth recovery:
    It takes 4-6 weeks for the joint to recover. A specific activity and rehabilitation program may be suggested. This will help speed your recovery and protect future joint function.
    Athletes often return to athletic competition within a few weeks.
    Note: Repair of the anterior cruciate ligament (ACL) by arthroscope may require a recovery time of 4-6 months and a more specialized rehabilitation program.

    Call Your Doctor

    Contact your doctor if your recovery is not progressing as expected or you develop complications such as:
    • Signs of infection, including fever and chills
    • Redness, swelling, increasing pain, excessive bleeding, or any discharge from the incision site
    • Persistent nausea and/or vomiting
    • Pain that you cannot control with the medications you've been given
    • Cough, shortness of breath, or chest pain
    • Joint pain, fatigue, stiffness, rash, or other new symptoms
    • Swelling, tingling, pain, or numbness in your toes that is not relieved by elevating your knee above heart level for 1 hour
    • Drainage
    If you think you have an emergency, call for medical help right away.
