Abstract

We investigated the three-dimensional geometry of the distal femur and simulated hemicondylar allograft reconstruction. The CT scan data of ten distal femurs allowed graphic reconstruction and three-dimensional projections utilizing least square fit techniques to determine the radii of each condyle. Three-dimensional reconstruction of several normal subjects was used to allow hemicondylar resection and reconstruction of cadaveric femurs. Using the rigid body spring model technique, the pressure distribution in contact regions was calculated assuming a one-legged stance. Defining the most relevant geometric parameters for pressure distribution, kinematic analysis is necessary.
