MCL injuries are common among active children and teens, especially as they return to sports practices and playground time at school. An MCL injury can range from a sprain to a full tear, and depending on its severity, extensive treatment may be required.

How Are MCLs Injured?

As one of the four main ligaments in the knee, MCLs (medial collateral ligaments) are responsible for stabilizing the knee. The most common way for MCL sprains and tears to occur are when the knee is struck on the side, causing it to unnaturally bend inwards towards the other knee. Another common way is if the leg below the knee bends out too far or twists.

Injured MCL Symptoms

You may experience different symptoms, depending on the sprain or complete tear of the MCL, or grade of the symptoms: 

  • Grade 1 Tear
    • Mild tenderness on the inside of the knee
    • Usually no swelling
    • Pain can be felt when knee is bent 30 degrees and when outward force is applied
    • No joint laxity
  • Grade 2 Tear

    • Moderate tenderness on the inside of the knee
    • Some swelling can occur over the MCL
    • Pain can be felt during stress test
    • Mild to moderate joint laxity with a definite end point
    • The knee cannot be completely bent sideways
  • Grade 3 Tear

    • Indicates a complete MCL tear
    • Pain can vary but is often not as severe as a Grade 2 tear

    • May have a wobbly or unstable knee.

Treatment for MCL Injuries

MCL Injury Treatment at FastMedThe best way to know how to treat your child’s MCL injury is to visit a medical professional. It can then be diagnosed as to whether the joint ligament is sprained or torn, and what your treatment options may be.

Most minor to moderate MCL injuries can be treated at home. A medical professional will recommend ice, rest, and anti-inflammatory medicine, in addition to crutches or a brace for more serious injuries. Gentle exercises and reduced physical activity may also be recommended.

For severe MCL injuries, surgery may be required.
