A meniscal tear is a tear in the meniscus. The meniscus is cartilage, which acts as a shock-absorbing structure in the knee. There are two menisci in each knee, a medial one on the inside, and a lateral one on the outside.
There are different types of tears depending on the location and how they look. Treatment depends on the severity of the tear.

Most injuries to the meniscus are caused by trauma. This usually includes compression and twisting of the knee. Because the aging process tends to break down the inner tissues of the meniscus, minor trauma can injure the meniscus in an older adult.
Factors that may increase your risk of a meniscal tear include:
Symptoms may include:
You will be asked about your symptoms and medical history. A physical exam will be done.
Your knee may need to be viewed. This can be done with:
Talk with your doctor about the best treatment plan for you. Recovery time ranges depend on the severity of your injury. Treatment steps may include:
Your knee will need time to heal. Avoid activities that place extra stress on the knee:
Your doctor may recommend a knee brace to stabilize the knee, and crutches to keep extra weight off your leg.
Apply an ice or a cold pack to the area for 15-20 minutes, four times a day, for several days after the injury. Do not apply the ice directly to your skin. Wrap the ice or cold pack in a towel.
To manage pain, your doctor may recommend:
Compression can help prevent more swelling. Your doctor may recommend an elastic compression bandage around your knee. Be careful not to wrap the bandage too tight.
Elevation can also help keep swelling down. Keep your knee higher than your heart as much as possible for the first 24 hours or so. A couple of days of elevation might be recommended for severe sprains.
Your doctor may refer you to a physical therapist. The therapist can help you control discomfort and regain function.
Use heat only when you are returning to physical activity. Heat may then be used before stretching or getting ready to play sports to help loosen the knee joint.
When the acute pain is gone, start gentle stretching as recommended. Stay within pain limits. Hold each stretch for about 10 seconds and repeat six times. Stretch several times a day.
Begin strengthening exercises for your legs as recommended.
Repair or removal of all or part of the damaged meniscus may by performed. This is usually done through small incisions of the skin. A camera and special tools are inserted through the incisions.
