title: Anatomical data and development of geometric models for the knee region bones.
abstract: Analytical geometric models for the bones of the knee region have been developed. A survey was done on real pieces to obtain the dimensions of the geometric sections used in each model. The dependence of the section dimensions on the bone length and the estimated dimensions of the bones for a 1.70 m tall person are presented. A parameter that attempts to relate the person's height to the bone length was included. Using reference data for the tissues and for bone composition, the models represent 8.7% (each knee) of a 10 kg skeleton and present the following densities: femur and tibia 1590 kg m(-3), fibula 1660 kg m(-3) and patella 1720 kg m(-3).
