Abstract: This
paper obtained the data of custom-made tibia, femoral joints and meniscus
morphology by studying relating researches and constructed several sagittal
section of the knee joint. Based on the 2D bone morphology of femoral condyle
and the contact radius relationship of the tibial plateau, it created the design
of the sphere curvature of femoral condyle to conform to the demands of the
patients. To simulate the various meshing curved surface between bones, this
paper considered using sphere to fit femoral condyle, using femur image data to
fit the femur into spheres and using the Hertz’s elastic contact theory to
construct a femur-tibia and femur-meniscus biomechanical model. Lastly, using
the contact stress and contact deformation obtained by solving the numeric
examples under specific cases can be used as a reference in the design and
production of future prosthesis.
