The geometry of the cruciate ligaments in the canine and equine knee joint, a Tchebychev mechanism.
The ratio between the length of the anterior and posterior cruciate ligaments and the distance between their femoral and tibial attachments in the canine and equine knee joint reveals that these structures form a Tchebychev mechanism for parallel motion.
