Anatomy means the 'shape' of the structures in the body, and how the different parts correspond to one another.

The anatomy of the knee seems quite simple, but the 'functional anatomy', ie how the pieces operate together, is quite complex.

The knee joint is really three separate joints - two 'tibio-femoral' joints (contact surfaces of tibia and femur), and one 'patellofemoral' joint (contact surface of patella and femur). The thinner fibula bone at the side of the tibia does not form part of the knee joint itself. 


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.

Simplified anatomy of the knee, with illustrations.

Arthroscopic Anatomy

Part 3 of a course on Diagnostic Arthroscopy by Dr (Mr) Angus Strover of the UK.

Diagnostic Arthroscopy

This course gives one an overview of the anatomy of the knee as the surgeon sees it during arthroscopy. The reader will get an idea of how the surgeon's view inside the knee is dependent upon the positioning of the portals and instruments.
