Abstract

The purpose of this paper was to investigate the anatomical location of the main axes of rotation of the knee. The study was performed as follows: joint motion registration by an electrogoniometer; joint digitization by the same electrogoniometer; computer reconstruction of motion and bone geometry; comparison of 4 hypotheses on correlation between the axis of flexion–extension and the femoral anatomy and between the axis of longitudinal rotation and the tibial anatomy in 6 human knees using an original geometrical interpolation. Our results suggest that: (a) the axis of flexion-extension lies in a cone spanned by the transepicondylar line and the so called FFc line [1]; (b) the axis of longitudinal rotation can be represented by a line parallel to the tibial anatomical axis intersecting the flexion axis in the medial compartment. Such a simplified frame for the representation of knee rotations may be useful and easily computed in computer-assisted knee reconstruction.
