Meniscus is cartilage in the knee joint. It helps to stabilize and cushion the knee. A meniscectomy is the removal of all or part of the meniscus.
Reasons for Procedure
A meniscectomy is done when the cartilage is damaged. Damaged cartilage can cause pain, or give you problems with knee motion.
Problems from the procedure are rare, but all procedures have some risk. Your doctor will review potential problems, like:
Factors that may increase the risk of complications include:
What to Expect

Talk to your doctor about your medications. You may be asked to stop taking some medications up to one week before the procedure, like:

Description of the Procedure
There are two methods for meniscectomy. The more common procedure is called arthoscopy. Arthrotomy, an open technique, is rarely used. This may also be referred to as an open meniscectomy.
Small incisions are made around the knee. Special tools are inserted into the knee joint. A tiny camera will provide a view of the inside of the knee. The damaged meniscus is either repaired or removed. The doctor will remove as little cartilage as possible. A drain may be inserted to drain away fluid. The incisions are closed with stitches. The stitches are usually removed in the doctor's office one week later.
A larger incision is made over the knee joint. The meniscus is then either repaired or removed. The incision is closed with stitches. It usually results in a longer recovery period. This process is usually done when there are problems with the knee that make the arthroscopic procedure difficult.
How Long Will It Take?
The procedure usually takes less than one hour.
How Much Will It Hurt?
Anesthesia will block pain during the procedure. You will have pain after the procedure. Ask your doctor about medication to help manage pain.
At the Care Center
Right after the procedure, the staff will monitor your recovery. The staff may give you:
If the meniscus was removed, it generally takes 3-6 weeks to return to full activities.
If the cartilage was repaired, it can take up to four months for full recovery. The goal of the first week is to reduce pain and swelling. After this, the goals are to increase range of motion and weight-bearing. Physical therapy is often done several times a week for four weeks or more. At 6-8 weeks, low impact activities can often be added. This will help to prepare you to return to sports or activities. Running, cutting, and rotation are avoided for at least 16 weeks.
