Biometrics of the four-bar link of the cruciate ligaments in projection on the flexion-extension plane of the human knee joint.

Abstract

Measurements on the proportions, angles and position were carried out on the four-bar link of the knee joint, which consists of femur, tibia and the guiding bundle of each cruciate ligament. Based on the these values it was possible to refute Menschik's kinematic concept of collateral ligament function.
