Arthroscopy

What is arthroscopy?

Arthroscopy is a minimally-invasive procedure. This means it uses only small incisions. It is used to diagnose and treat conditions that affect joints. The surgeon can directly view the inside areas of a joint using a tool called an arthroscope. This is a small, tube-shaped tool that is used to look inside a joint.

Orthopedic surgeons use arthroscopy to diagnose and treat joint problems. The scope has a system of lenses, a small video camera, and a light for viewing. The camera is connected to a video screen. This lets the surgeon see a joint through a very small incision. The arthroscope is often used along with other tools that are put through another incision.

Arthroscopy is most often used on the knee. But arthroscopy can be used in other joints. These include:

  • Shoulder

  • Elbow

  • Ankle

  • Hip

  • Wrist

Why might I need arthroscopy?

Arthroscopy may be used to diagnose and help treat:

  • Inflammation in the knee, shoulder, elbow, wrist, or ankle

  • Shoulder rotator cuff tendon tears

  • Impingement syndrome, which causes pinching of tendons in the shoulder due to squeezing or rubbing of the rotator cuff and shoulder blade

  • Cartilage damage, such as tears, injury, or wear

  • Ligament tears with instability in the knee

  • Tendon damage

  • Loose bone or cartilage in the knee, shoulder, elbow, ankle, wrist, or hip

Arthroscopy may be used to do a biopsy. It can be used to do corrective surgery. For example, torn ligaments can be repaired or reconstructed. Arthroscopic surgery may remove the need for an open surgical procedure.

There may be other reasons for your healthcare provider to advise an arthroscopy.

What are the risks of arthroscopy?

All surgery has risks. The risks of this surgery include:

  • Bleeding

  • Infection

  • Blood clots in the legs or lungs

There may be other risks depending on your overall health. Talk about any concerns you have with your healthcare provider before the procedure.

How do I get ready for arthroscopy?

  • Your healthcare provider will explain the procedure to you. Ask any questions that you have about the procedure.

  • You will be asked to sign a consent form. This gives your permission to do the procedure. Read the form carefully. Ask questions if something is not clear.

  • Your healthcare provider will ask about your health history. He or she may give you a physical exam to make sure that you are in good health before having the procedure. You may have blood tests or other tests.

  • Tell your healthcare provider if you are sensitive to or are allergic to any medicines, latex, tape, and anesthetic agents (local and general).

  • Tell your healthcare provider of all medicines (prescribed and over-the-counter) and herbal supplements that you are taking.

  • Tell your healthcare provider if you have a history of bleeding disorders or if you are taking any anticoagulant (blood-thinning) medicines, aspirin, or other medicines that affect blood clotting. It may be necessary for you to stop these medicines before the procedure.

  • If you are pregnant or suspect that you are pregnant, you should notify your healthcare provider.

  • You will be asked to not eat for 8 hours before the procedure, generally after midnight.

  • You may receive a sedative before the procedure to help you relax. Because the sedative may make you drowsy, you will need to arrange for someone to drive you home.

  • Based on your medical condition, your healthcare provider may request other specific preparation.

What happens during arthroscopy?

Arthroscopy may be done on an outpatient basis. Or it may be done as part of your stay in a hospital. Procedures may vary depending on your condition and your healthcare provider's practices. Arthroscopy may be done while you are asleep under general anesthesia. Or it may be done while you are awake under local anesthesia. The type of anesthesia will depend on the type of procedure and your overall health. Your anesthesiologist will talk with you in advance.

Generally, an arthroscopic procedure follows this process:

  1. You will be asked to remove clothing and will be given a medical gown to wear.

  2. An IV line may be put in a vein in your arm or hand.

  3. If there is a lot of hair at the surgical site, it may be shaved off.

  4. You will be positioned on an operating table to provide the best access to the joint to be treated.

  5. The anesthesiologist will watch your heart rate, blood pressure, breathing, and blood oxygen level during the surgery.

  6. The skin over the surgical site will be cleaned with an antiseptic solution.

  7. The surgeon may drain blood from the surgical area by elevating the extremity and/or applying an elastic wrap to the extremity. The surgeon may inject a fluid solution such as saline before the arthroscope is inserted. This is done to help expand the joint.

  8. The surgeon will make an incision in the joint area.

  9. The arthroscope will be inserted through the incision, into the joint.

  10. Other incisions may be made to put other small tools that do grasping, probing, or cutting.

  11. Corrective surgery may be done if needed.

  12. The incision will be closed with stitches or adhesive strips.

  13. A sterile bandage or dressing will be applied.

What happens after arthroscopy?

After surgery, you will be taken to the recovery room. Your recovery process will vary depending on the type of anesthesia you had. The blood flow and feeling in the joint will be checked. Once your blood pressure, pulse, and breathing are stable and you are alert, you will be taken to your hospital room. Or you will be discharged to go home. Arthroscopic surgery is usually done on an outpatient basis.

Once you are home, keep the incision site clean and dry. Your healthcare provider will give you bathing instructions. If stitches are used, they will be removed during a follow-up office visit. If adhesive strips are used, they should be kept dry and will fall off within a few days.

Take a pain reliever for soreness as advised by your healthcare provider. Aspirin or some other pain medicines may increase the chance of bleeding. Be sure to take only approved medicines.

Limit your activity and the use of the joint for 24 to 48 hours after a diagnostic arthroscopy. If other procedures are done, such as a ligament repair, your activity and use of your joint may be limited for a longer period. Your healthcare provider will give you specific instructions. For knee surgery, you may be given an immobilizer to wear. Your healthcare provider may tell you to put ice on the surgical site and to elevate the knee when you sit.

Tell your healthcare provider if you have any of these:

  • Fever or chills

  • Redness, swelling, bleeding, or other fluid leaking from the incision site

  • Pain around the incision site that gets worse

  • Numbness or tingling in the affected extremity

You may resume your normal diet unless your healthcare provider advises you differently.

Your healthcare provider may give you other instructions after the procedure.
