An orthopedic artificial tibia including a tibial baseplate is provided. The orthopedic prosthetic tibia assists in proper positioning and orientation relative to the resected tibia, and further provides improved range of motion, soft tissue interaction, and long-term fixation of the completed prosthetic knee. A tibial base plate having an asymmetric outer periphery to facilitate is provided. The asymmetric perimeter of the base plate is formed in a size and shape that substantially matches the various perimeters of the resected typical proximal tibial surface, so it is clearly adequate by placing the base plate over the tibia Position and orientation. The outer periphery of the base plate is intentionally provided with irregularities and / or gaps located between the outer periphery of the base plate and the outer periphery of the bone. For example, to prevent a deeply bent part from hitting at the posterior-inner part 224 and to avoid improper interaction between the iliac ligament and the prosthetic component at the anterior-outer part 210. .
