Abstract: An artificial joint includes a first engagement structure, a first connecting member, a second engagement structure, and a second connecting member. The first engagement structure has an external gear. The first connecting member is connected to the first engagement structure and configured to connect a femur. The second engagement structure has an internal gear. The external and internal gears are meshed with each other respectively based on a first pitch circle and a second pitch circle. The first pitch circle is greater than the second pitch circle. The center of the second pitch circle is located within the first pitch circle. The second connecting member is connected to the second engagement structure and configured to connect a tibia.
