What is the motion of the thigh band if the mechanical knee axis is located below the anatomical knee axis?

When the mechanical knee axis is located below the anatomical knee axis, the thigh band experiences a proximal motion. This positioning creates a scenario where the alignment and functioning of the knee joint are affected by the relative locations of the mechanical and anatomical axes.

In prosthetics, when the mechanical axis is lower, it means that during ambulation or weight-bearing activities, the thigh band needs to adjust to accommodate the shift in axis. This results in the thigh band being pulled or positioned more closely to the body, which is described as proximal motion.

Proximal motion is crucial in ensuring stability and facilitating proper gait mechanics. It allows for better alignment of the entire lower limb, which is essential in preventing added stress on other joints and creating a smoother, more efficient movement pattern.

Understanding these principles is vital for practitioners in orthotics and prosthetics, as they need to consider how various configurations affect the fit and function of devices. By recognizing the relationship between the mechanical and anatomical axes, professionals can make informed adjustments to optimize patient outcomes.
