[Biomechanical analysis of the normal knee and with cranial cruciate ligament rupture to the cranial translation degree and articular stiffness in dogs].

Purpose: To analyse the biomechanical function of the knee joint in dogs, comparing the cranial translation degree and articular stiffness of the tibia in relation to the femur, in normal joints and joints with rupture of cranial crucial ligament.

Methods: Ten mongrel dog knees were analyzed, weighting more than 20 kg. Biomechanical analysis to the cranial translation degree of the knee joint with normal cranial cruciate ligament and surgically sectioned was made.
