What would be the result of a strong knee extension moment in terms of foot placement?

A strong knee extension moment typically occurs when there is excessive force attempting to straighten the knee joint. In the context of lower limb biomechanics and prosthetic use, this force has a notable impact on foot placement. If the knee is excessively extending, it causes the ankle and foot to move forward in relation to the knee joint.

As a result, the foot placement would be positioned too anterior, meaning it is located too far forward compared to the line of the knee. This can lead to instability during ambulation, as the center of mass may shift forward, potentially compromising balance and gait efficiency.

In contrast, foot placements that are too posterior, inset, or outset do not directly result from a strong knee extension moment. These placements generally pertain to different alignment issues that could affect stability and gait, but they do not inherently relate to the mechanics of knee extension moments. Thus, foot position being too anterior accurately reflects the biomechanical consequence of a strong knee extension moment.
