Schematic illustration of the knee joint from frontal. Visible are the thigh bone (femur), kneecap (patella) and lower leg bones (tibia and fibula). Also illustrated are the ligaments of the knee (white), e.g. the patellar tendon (patellar lig.), the external ligaments (collateral fibular / tibial lig.), as well as the ligamentous structure between tibia and fibula (interosseus membrane). In the joint gap the frontal surfaces of the menisci are visible.
