The tibia is the shin bone.

 

Key tibia anatomy in the knee joint

That part of the tibia which is central to the function of the knee joint is the flat upper surface - the tibial plateau.

Illustration from the top of the tibial plateau, showing the key structures - the two menisci and the two cruciate ligaments. X-ray from the front, showing the tibial plateau, with the central spines where the cruciate ligaments (which do not show on X-ray) are attached. The two menisci sit atop the tibial plateau. They are not evident on the X-ray, appearing only as a 'gap' between the two long bones.

Knee anatomy intro

This page demonstrates the bones of the knee - femur, tibia, and patella. The shock-absorbing menisci fill the gap between the rounded ends of the femur bone and the flattened upper surface of the tibia bone. The cruciate ligaments act as a 'stay' to allow movement of the femur and tibia, without the movement being excessive.
