The Unhappy Triad I

Have you ever heard of the unhappy triad?

The unhappy triad refers to a sprain injury in 3 of the structures in the knee. These structures include the anterior cruciate ligament (ACL), the medial collateral ligament (MCL), and the medial meniscus.

This injury often occurs when a lateral force is applied to the knee when the foot is fixed on the ground. This increases the valgus and rotational stress in the knee and overstretches the ligaments, causing the knee to fail.

When the ligaments fail, there is more stress placed on the medial meniscus, leading to the rupture of the medial meniscus.

This injury is commonly seen in contact sports such as football, rugby, and soccer.

Hope you learn more about the unhappy triad today. Stay tuned for symptoms and treatment next week!
