Valgus & Varus Forces on the Knee | MCL vs LCL Injuries

The video tutorial explains the forces that affect the medial collateral ligament (MCL) and lateral collateral ligament (LCL) of the knee. It distinguishes between varus and valgus forces, describing how these forces impact knee alignment and ligament damage. The tutorial highlights that valgus forces, which push the knees inward, are more common and often result in MCL injuries. It also discusses the concept of the unhappy triad, where the MCL, ACL, and medial meniscus are torn. The video emphasizes understanding these forces to predict and prevent knee injuries.
