title: A stress analysis of the proximal tibia after insertion of the endoprosthesis.
abstract: Detailed investigation for the local stress increment at the fixation post bottom of an artificial knee joint was performed by two-dimensional finite element method. A strain measurement was also conducted by wire strain gauges on a cancellous bone with a special method. It was made clear that a curvature with a certain extent of radius was necessary for the corner of a fixation post and application of acrylic cement with a certain extent of thickness (3 mm less than or equal to) was effective for stress relaxation, and that an optimum value (10(-1)-10 GPa) existed for elastic modulus of bone cement.
