M S, the knee joint is a very simple and complex one all at the same time. The strengths of the joint are in the redundancies it has. For example the ACL is not the first line of stability in the knee but the hamstrings and the gastrocs are. When they fail or the stress is too much for them the ligament goes. This system of redundancy is found on all sides of the knee. The joint becomes more stable the stronger the muscles are. The weakness of the joint come from the fact that is is essentally a stick with rubberbands stabilizing it. There is a law in physics that states where there is strength or stability there is no flexibility and where there is flexibility there is no strength. The knee is that in essence. The joint itself is built around two ball bearings that are not of equal size and they are supported in two cups of shallow depth and also of unequal size and stabilization. There is a hinge joint at the knee but it is not that simple for at the same time there is a rotational movement that locks the knee when it is in full extension. The joint is most stable when it is in full extension and most unstable with flexion. The knee is most vulnerable to injury when it is in full or almost full extension for there is no give and the muscles cannot really stabilize it therefore exposing the ligaments to excessive force.
