"We advise kids not to specialize in just one sport. Multi-sport athletes tend not to get as many meniscal tears and other acute and overuse injuries. And for practicing, we advise kids and coaches to alternate exercises and vary drills. In the long term, your muscle memory is better if you change up your practice exercises."

--Orthopedic Team, Boston Children's Hospital Orthopedic Center

With more and more kids playing organized sports, there’s been a rise in the number of overuse injuries, as well as acute injuries like meniscus tears, among children and adolescents.

If your child or teen has been diagnosed with a torn meniscus, we at Children’s Hospital Boston know that he’s experiencing discomfort, as well as some disappointment at the disruption of his sports training. We’ll approach your child’s treatment with sensitivity and support. We want to get your child back to his normal activities—and back into his game safely.

About meniscus tears (also called meniscal tears)

  • A meniscus tear is sometimes thought of as an overuse injury, but is more accurately classified as an acute injury, usually from sports.
  • The meniscus is a wedge-shaped structure in the knee that consists of fibrocartilage—a very tough but pliable material.
  • The medial meniscus is located on the inside of the knee (toward the middle of the body) and the lateral meniscus is located on the outside of the knee.
  • In the knee joint, the menisci act primarily as stabilizers and shock absorbers between the thigh bone and the shin bone.
  • Compressing or twisting the knee can tear the meniscus, a common injury in sports such as football.
  • More than 500,000 meniscal tears happen in the United States every year.
  • Meniscal tears are often associated with injuries to the anterior cruciate ligament (ACL).
  • Meniscal tears can lead to early arthritis.

If a piece of torn meniscus isn't removed and "floats" around the knee, it may cause the joint to lock.

Signs that your child's knee has a torn meniscus include:

  • a popping sensation
  • swelling or stiffness
  • pain associated with twisting or rotating the knee
  • difficulty in fully straightening the knee, or feeling like the knee is locking

Meniscus tears can often be prevented with:

  • proper conditioning and training (especially cross-training)
  • sport-appropriate equipment and protective gear
  • adequate rest between exercise sessions
