What angle is the knee in during the loading response phase?

During the loading response phase of the gait cycle, the knee is typically in a flexed position to absorb shock and accommodate the weight of the body as it transitions from the stance phase of the prior leg to the swing phase. At this stage, there is a need for joint flexion to provide stability and support under load. The angle of 15-18 degrees of flexion is considered optimal because it allows for adequate weight distribution across the knee joint while maintaining the necessary balance and control. This degree of flexion ensures that the knee can adequately absorb forces during the transition, facilitating a smooth gait cycle and protecting the joint from excessive strain.
