Objective To establish a 3-dimensional (3-D) finite element knee model in healthy Chinese males,to verify the validity of the model,and to analyze the biomechanics of this model under axial load,flexion moment,varus/valgus torque,and internal/external axial torque.Methods A set of consecutive transectional computerized tomography images of normal male knee joints in upright weight-bearing position was selected.With image processing and inversion technology,the 3-D finite element model of the normal knee joi...
