>>7603632>>7603637While there is only on joint in the knee, and those on paper makes logical sense a single mechanical joint will emulate it fine, the problem is the Knee is NOT a mechanical joint.
Due to the way the knee works a double joint provides the simulation of the effect of the huge ass gap in the joint of the bones, while the middle piece of the joint simulates the effect of tissue covering up that gap.
while most offerings of double joints are lazily put together at best, you get examples like
>>7602918 that show double joints is the right path to go for a more accurate simulation of the knee. It still is not perfect and it never will be, but we can strive to get as close as possible until the day comes when they can create synthetic flesh covered figures complete with fully accurate tendons.
