To correct genu valgum, forces should be applied over which locations?

To address genu valgum, which is characterized by an abnormal angling of the knees that causes them to tilt inward, forces need to be strategically applied to counteract the alignment issues. The rationale behind the correct choice involves targeting specific anatomical locations to create proper alignment.

Applying forces to the lateral thigh distal to the greater trochanter helps to realign the femur and counteract the inward angulation of the knees. This helps reduce the medial stress on the joint and promotes a more neutral knee position. Additionally, exerting force on the lateral aspect of the foot aids in realigning the foot in relation to the lower leg, ensuring that the center of gravity is maintained over the foot and promoting correct loading patterns during ambulation. Finally, applying force to the medial condyle of the femur provides a counteractive force against the tendency for the femurs to angle incorrectly.

This combination of force applications is critical in achieving a correction in the alignment and function of the knee joint in patients with genu valgum. Each of these points works collaboratively to distribute load properly, enhance joint stability, and promote proper alignment throughout the lower extremity.
