Which ligament is responsible for resisting valgus forces during knee flexion?

• A. Patellar ligament
• B. Medial collateral ligament
• C. Lateral collateral ligament
• D. Anterior cruciate ligament

Answer: (B)

The medial collateral ligament (MCL) is primarily responsible for resisting valgus forces, which are forces that push the knee inward towards the midline of the body. During knee flexion, the MCL plays a critical role in maintaining the stability of the knee joint by preventing excessive lateral movement and ensuring proper alignment of the femur and tibia. The MCL connects the femur to the tibia on the inner side of the knee and is particularly active in situations where the knee is flexed and subjected to forces that could lead to excessive inward angulation. This protective function is crucial for activities involving weight-bearing and directional changes, which can otherwise put the knee at risk of injury. Understanding the role of the MCL emphasizes the need to focus on knee mechanics and injury prevention strategies, particularly for athletes and individuals engaged in physical activities that stress the knee joint.
