The femur is the thigh bone.


Anatomy of the femur in the knee joint

Only the lower  (distal) end of the femur forms part of the knee joint. Together with the plateau of the tibia, the bony ends are encased by the knee capsule so that the joint is water-tight.

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.
