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

When considering the motion of the thigh band in relation to the mechanical and anatomical knee axes, it’s important to understand how these axes relate to the positioning and function of orthotic devices.

If the mechanical knee axis is positioned above the anatomical knee axis, this indicates that the orthotic design has created a situation where the mechanical function (the designed movement of the knee in the orthotic) is adjusted relative to where the knee naturally articulates. In this scenario, the thigh band will move distally (downward) as it seeks to align better with the lower portion of the limb and joint positioning. The distal motion helps maintain stability and function by allowing for appropriate alignment of the orthotic device.

In this case, the other options may describe various potential movements but do not accurately reflect the alignment adjustments needed when the mechanical knee axis is above the anatomical one. The focus on distal motion emphasizes the necessity of ensuring that the orthotic structure aligns properly with the functional aspects of the knee joint during use.
