What is the position of the knee during midstance?

During midstance in the gait cycle, the knee is typically in a position of approximately 15 degrees of flexion as it transitions from flexion toward extension. This slight degree of flexion is essential for maintaining stability and absorbing impact forces as the body moves over the supporting leg. If the knee were fully extended, it would lack the necessary joint mobility and shock absorption required during this phase of gait. Moreover, having the knee in a more flexed position allows the muscles and tendons around the joint to engage effectively, providing both stabilization and the preparation needed for the subsequent phases of the gait cycle. This slight flexion is a natural part of the walking process, facilitating smoother movement and reducing stress on the knee joint itself.
