Meniscus Surgery: Before Your Surgery

What is meniscus surgery?

Meniscus surgery removes or fixes the cartilage between the bones in the knee. This cartilage is called the meniscus. Each knee has two of these rubbery pads of cartilage, one on either side. When a meniscus tears, your knee may be painful, swell, get stiff, or lock up.

Your doctor may use small tools to remove parts of the damaged meniscus and smooth the edges. This is called a partial meniscectomy (say "men-ih-SEK-tuh-mee"). In some cases, tears in the meniscus can be sewn back together. But if your meniscus can't be repaired, the doctor may remove the damaged part.

Meniscus surgery is usually done as arthroscopic surgery. Your doctor uses a lighted tube called an arthroscope, or scope. Your doctor puts the scope and other surgical tools through small cuts in your knee. These cuts are called incisions. They leave scars that usually fade with time.

The surgery will take at least 1 hour. Most people go home the same day of the surgery. You may have to use crutches after surgery. If so, be sure you have a backpack or clothes with a lot of pockets to carry items.

You may be able to go back to school in 1 to 2 weeks. If you have a job and you sit at work, you may be able to go back in 1 to 2 weeks. But if you are on your feet at work, it may take 4 to 6 weeks. If you are very physically active in your job, it may take 3 to 6 months.

You may need physical rehabilitation (rehab) after surgery. The program may last for several months. At first, your physical therapist will work with you. Later, you will get exercises to do on your own. After surgery and rehab, you are likely to have less pain and more flexibility in your knee. How soon you can return to sports or exercise depends on how well you follow your rehab program and how well your knee heals. If you had a partial meniscectomy, you might be able to play sports in about 1 to 2 months. If you had meniscus repair, it may be 3 to 6 months before you can play sports.

What happens on the day of surgery?

• 
  Follow the instructions exactly about when to stop eating and drinking. If you don't, your surgery may be canceled. If your doctor told you to take your medicines on the day of surgery, take them with only a sip of water.
•  
  Take a bath or shower before you come in for your surgery. Do not apply lotions, perfumes, deodorants, or nail polish.
•  
  Do not shave the surgical site yourself.
•  
  Take off all jewelry and piercings. And take out contact lenses, if you wear them.
