1. An animal knee joint implant that reflects an anatomical structure of an animal that is a quadruped, the animal knee joint implant comprising:
a tibia element configured to be coupled to a proximal portion of a tibia of the animal, the tibial element comprising:
a tibia contact surface configured to contact with a tibia of the animal;
a seating surface opposite of the tibia contact surface, the seating surface being a planar surface extending between a medial side of the tibia element and a lateral side of the tibia element, the seating surface being inclined posteriorly and laterally such that a medial height of the tibia element extending between the seating surface and the contact surface at the medial side is higher than a lateral height of the tibia element extending between the seating surface and the contact surface at the lateral side when the contact surface is horizontally disposed;
a post protruding from the seating surface so as to be perpendicular to the seating surface, the post being inclined laterally and posteriorly when the contact surface is horizontally disposed; and
a tibia stem outwardly protruding from the tibia contact surface and being inclined posteriorly when the contact surface is horizontally disposed;
a femur element having medial and lateral condyles; and
a bearing element seated on the seating surface of the tibia element and configured to support the medial and lateral condyles of the femur element, the bearing element encircling the post with the bearing element and the seating surface being configured so that the bearing element can freely rotate about the post while being seated directly on the planar seating surface.
