The use of artificial bones in implant testing has become popular due to their low variability and ready availability. But the hole, which is created during the production process in located proximal tibia, is apprehended to change stress distribution pattern and make stress concentration. The purpose of this study was to analysis of stress distribution pattern & micromotion deviation between cancellous bone and baseplate according to hole using finite element analysis (FEA). von Mises Stress around the hole at medial, lateral on the cortical surface was measured 63.1%, 66.6% higher than the filled hole model, respectively. But Micromotion between tibia and baseplate was similarly measured in the safe region(0~45μm). These results indicate that mechanical test with artificial bone should be considered the effect of poximal tibia hole.
