I may be misunderstanding you, but it seems like youre saying the ACL is isolated system only affected by what the lower and upper leg does and is not affected by how the entire body is positioned or what its doing. The function of holding the lower leg to the upper is an important part of a much larger chain designed to support our entire being. Its orientation in space, connection to other muscles, amount of work required of it, and how energy is exerted, held or absorbed will inherently change as we introduce varied degrees of movement and forces in different directions. A simple way to feel this is to flex your toes upward; you will feel the tension in your knee because it's hugely affected by how the foot is oriented. If you push it down, the knee is serving a very different specific function and will be pressured in a different manner. If you twist your leg it's yet another plane of energy a knee is being tested. https://chatgpt.com/share/6868a37d-b...f-dac488968f56
