Meniscus Tear in Teens: Care Instructions

Meniscus tear


The meniscus is rubbery tissue in the knee that acts as a shock absorber between the upper and lower leg bones. The meniscus also keeps your knee stable by spreading weight across it. Each knee has two menisci (plural of meniscus). You can tear a meniscus if you plant your foot and twist, or pivot. The meniscus also can wear down as you age, and it can tear from squatting or kneeling.

Small tears may heal on their own with rest and some physiotherapy. But a more serious tear may need surgery to repair it or to remove part of the meniscus. Your doctor may want you to see a doctor who specializes in bones and sports injuries.

Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse advice line (811 in most provinces and territories) if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.

How can you care for yourself at home?

  • Rest your knee when possible.
  • Do not squat or kneel.
  • Take pain medicines exactly as directed.
    • If the doctor gave you a prescription medicine for pain, take it as prescribed.
    • If you are not taking a prescription pain medicine, ask your doctor if you can take an over-the-counter medicine.
  • Put ice or a cold pack on your knee for 10 to 20 minutes at a time. Try to do this every 1 to 2 hours for the next 3 days (when you are awake) or until the swelling goes down. Put a thin cloth between the ice and your skin.
  • Prop up the sore leg on a pillow when you ice your knee or any time you sit or lie down during the next 3 days. Try to keep your leg above the level of your heart. This will help reduce swelling.
  • Follow your doctor's directions for using crutches or a knee brace, if suggested.
  • Follow your doctor's directions for exercises to keep your knee mobile and your leg muscles strong. Here are a few exercises you can try if your doctor says it is okay.
    • Quad sets: Lie down on the floor or the bed with your injured leg straight. Fully extend your leg—there should be no or little bend in your knee. Tighten the thigh (quadriceps) of your injured leg for 6 seconds. Do not lift your heel up. Relax your quadriceps for 10 seconds. Repeat this exercise 8 to 12 times several times during the day.
    • Straight-leg raises: Lie down on the floor or the bed with your injured leg flat and your uninjured leg bent so that the bottom of your foot is on the floor or bed. Tighten the quadriceps of your injured leg. Keeping your knee as straight as possible, lift your injured leg off the bed until it is about 45 centimetres (18 inches) above the bed or floor. Lower your leg back down and relax for 5 seconds. Do 3 sets of 20 repetitions, or if you tire quickly, 3 sets of 8 to 12 repetitions.
    • Heel raises: Stand with your feet 8 to 10 centimetres (3 to 4 inches) apart. Rest your hands lightly on a counter or chair in front of you. Slowly raise your heels off the floor while keeping your knees straight. Hold for 3 seconds, then slowly lower your heels to the floor. Do 3 sets of 8 to 12 repetitions.
    • Heel slides: Lie down on the floor or the bed with your leg flat. Slowly begin to slide your heel toward your rear end (buttocks), keeping your heel on the floor. Your knee will begin to bend. Slide your heel and bend your knee until it becomes a little sore and you can feel a small amount of pressure inside your knee. Hold this position for 10 seconds. Slide your heel back down until your leg is straight on the floor. Relax for 10 seconds. Repeat this exercise 20 times.

When should you call for help?

Watch closely for changes in your health, and be sure to contact your doctor or nurse advice line if:

  • You have increasing knee pain or swelling or both.
  • Your knee is so sore or stiff that you cannot walk on it.
  • You do not get better as expected.
