Knee Surgery and Arthroscopy

By Dr. Richard Edelson

Typically a healthy patient can go home the same day after having arthroscopic knee surgery. Be sure to talk over the details with your hospital or surgical center. When you are preparing for this surgery, you should adhere to normal precautions. For example, you should not eat or drink after midnight on the night preceding your surgery. Be sure to arrive at the hospital an hour or two before your surgery is scheduled so you will have plenty of time for preparation.

When you get to the hospital a member of the anesthesia team will evaluate you to determine which kind of anesthesia will work best for you. There are three anesthesia options with knee arthroscopy. You may have general, regional or local anesthesia. If you have general anesthesia, you will go to sleep. If you have regional anesthesia, you will be anesthetized below the waist. Local anesthesia will just number your knee.

If regional or local anesthesia are used, you will be awake during your surgery. If this is the case, you will be able to watch your surgery on a monitor if you wish.

Initially, your orthopedic surgeon will make a few small incisions in your knee. After this, your knee joint will be irrigated with a sterile solution that will wash any cloudy fluid away. This will enable the surgeon to have a clear view of the interior of your knee.

At this point, the surgeon will use an arthroscope to look into your knee and diagnose your problem. The surgeon (and you if you wish) will be able to see an image of the interior of your knee projected on a monitor. This image will enable the surgeon to guide the arthroscope to view the interior of your knee. For surgical treatment, your surgeon will have an assortment of small surgical instruments that can be inserted into your knee through the incisions. Your surgeon may use small clamps, scissors, lasers, and motorized shavers among other sophisticated instruments.

This part of the procedure will last forty-five minutes to an hour-and-a-half.

With knee arthroscopy, you can expect some of these treatments to occur:

Inflamed synovial tissue may be removed.

A torn cruciate ligament may be reconstructed.

Loose fragments of cartilage or bone may be removed.

Torn sections of articular cartilage may be trimmed.

Torn meniscal cartilage repair or removal.

When your surgery is done, your surgeon will either stitch or tape your incisions and will cover them with a bandage.

At this point, you will be taken to the recovery room. In an hour or two you will be ready to go home. Of course, you must have someone waiting to drive you.
