The collapse of the medial arch can increase pressure on which part of the knee?

The collapse of the medial arch, commonly associated with flatfoot or overpronation, can lead to a shift in the alignment of the lower extremities. When the medial arch collapses, the foot tends to roll inward, which alters the biomechanics of the entire leg. This excessive pronation can cause increased internal rotation of the femur and tibia.

As a result, the altered alignment and shift in weight distribution can place additional stress on the lateral aspect of the knee. The lateral side becomes overworked to accommodate the change in mechanics, leading to increased pressure and potentially resulting in conditions such as iliotibial band syndrome or patellar tracking issues. This is why the lateral side of the knee is particularly affected in cases of medial arch collapse, highlighting the interconnectivity of joint mechanics and foot alignment in overall movement patterns.
