Knee replacement surgery has become one of the most common orthopedic procedures performed on older people suffering from osteoarthritis. In an aging society, the demand for knee replacement surgery is predicted to rise. The goal of this project was to design a mechanism for evaluating knee replacements that simulates the motion of a knee replacement during walking. The team designed a mechanism that accommodates a 3D printed total knee replacement. The knee replacement within the mechanism reproduces the correct angular displacement between the tibia and femur and the angular displacement of the femur swing according to our kinematic analyses. It is hoped that future iterations of this mechanism can be used for the evaluation of knee replacement designs.
