Integrated system of finite element analysis approach to surgical decision-making. (A) both training and prediction need to use the force caused by body weight and femoral bicondylar angle change for extracting biomechanical features. (B) train the relationship between the biomechanical strain information and the risk factor of UKA revision. (C) predict and validate the risk factor of UKA revision.
