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 2 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.
Older adults and men are at increased risk. Factors that may increase your risk of:
Occupations that involve kneeling and squattingClimbing stairsPrevious knee injuriesObesity
Participating in contact sports, such as soccer or rugbyPoor techniques for jumping, landing, pivoting, and cutting
Symptoms may include: A popping sound at the time of the injuryPain and swelling in the kneeTightness in the kneeLocking up, catching, or giving way of the kneeTenderness in the joint
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: X-rayMRI scanArthroscopy
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:

Ice—Ice therapy may help relieve swelling. You may be advised to use heat as you begin to return to normal activities. Compression—Compression bandages can provide gentle pressure to help move fluids out of the area. Elevation—Keeping the knee elevated can help fluids drain out or prevent fluids from building upA knee brace to stabilize the kneeCrutches to keep extra weight off of the leg
Over-the-counter or prescription medication may be advised to reduce pain.
A physical therapist will assess the knee. An exercise program will be created to help recovery and to stretch and strengthen the muscles.
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.
