Three different types of pain relief (anesthesia) may be used for knee arthroscopy surgery:
- Local anesthesia. Your knee may be numbed with pain medicine. You may also be given medicines that relax you. You will stay awake.
Spinal anesthesia. This is also called regional anesthesia. The pain medicine is injected into a space in your spine. You will be awake but will not be able to feel anything below your waist. General anesthesia. You will be asleep and pain-free.
- Femoral nerve block. This is another type of regional anesthesia. The pain medicine is injected around the nerve in your groin. You will be asleep during the operation. This type of anesthesia will block out pain so that you need less general anesthesia.
A cuff-like device may be put around your thigh to help control bleeding during the procedure.
A narrow tube with a tiny camera on the end will be inserted through one of the cuts. The camera is attached to a video monitor that lets the surgeon see inside the knee.
At the end of your surgery, the saline will be drained from your knee. The surgeon will close your cuts with sutures (stitches) and cover them with a dressing. Many surgeons take pictures of the procedure from the video monitor, You may be able to view these pictures after the operation so that you can see what was done.
Why the Procedure Is Performed
Arthroscopy may be recommended for these knee problems:
meniscus. Meniscus is cartilage that cushions the space between the bones in the knee. Surgery is done to repair or remove it.
Torn or damaged
anterior cruciateligament (ACL) or posterior cruciateligament (PCL)
Swollen (inflamed) or damaged lining of the joint. This lining is called the synovium.
Kneecap (patella) that is out of position (misalignment).
Small pieces of broken cartilage in the knee joint
Baker’s cyst. This is a swelling behind the knee that is filled with fluid. Sometimes the problem occurs when there is swelling and pain (inflammation) from other causes, like arthritis.
Some fractures of the bones of the knee
The risks for any anesthesia are:
- Allergic reactions to medicines
The risks for any surgery are:
Additional risks for this surgery include:
- Bleeding into the knee joint
- Damage to the cartilage, meniscus, or ligaments in the knee
Blood clotin the leg
- Injury to a blood vessel or nerve
- Infection in the knee joint
- Knee stiffness
Before the Procedure
Always tell your doctor or nurse what medicines you are taking, even drugs, supplements, or herbs you bought without a prescription.
During the 2 weeks before your surgery:
- Your doctor may tell you to stop taking medicines that make it harder for your blood to clot. These include aspirin, ibuprofen (Advil, Motrin), naproxen (Naprosyn, Aleve), and other blood thinners.
- Ask your doctor which medicines you should still take on the day of your surgery.
- Tell your doctor if you have been drinking a lot of alcohol (more than 1 or 2 drinks a day).
- If you smoke, try to stop. Ask your doctor for help. Smoking can slow down wound and bone healing.
- Always let your doctor know about any cold, flu, fever, herpes breakout, or other illness you have before your surgery.
On the day of your surgery:
- You will usually be asked not to drink or eat anything for 6 to 12 hours before the procedure.
- Take the medicines your doctor told you to take with a small sip of water.
- Your doctor or nurse will tell you when to arrive at the hospital.
After the Procedure
You will have an ace bandage on your knee over the dressing. Most people go home the same day they have surgery. Your doctor will give you exercises to do.
Full recovery after knee arthroscopy will depend on what type of problem was treated.
Problems such as a torn meniscus, broken cartilage, Baker’s cyst, and problems with the synovium are often easily fixed. Many people stay remain active after these surgeries.
Recovery from simple procedures is usually fast. You may need to use crutches for a while after some types of surgery. Your doctor may also prescribe pain medicine.
Recovery will take longer if you have had a more complex procedure. If parts of your knee have been repaired or rebuilt, is you may not be able to walk without crutches or a knee brace for several weeks. Full recovery may take several months to a year.
