Total Knee Arthroplasty (TKA) treatment has been widely used for knee joint, having the most complex motion sequences and shape of the body, in case of loss of motion ability such as gonarthrosis. Lots of failures such as loosening, wear and instability have occurred as a result of increasing usage period. Instability is the most commonly seen failure associated with fixation. Especially loosening of tibial component is more common than that of femoral component. Evaluation of bone in terms of shape related with patient’s weight, height and gender is required to increase the success of TKAs comprising traditional tibial components. Most of the current commercially available knee prostheses are designed based on the anthropometric data of Caucasian knees. This means an accordance problem for the people in different regions having different joint size. In this study, a patient specific tibial component has been designed according to cutting surface of tibial bone obtained from the patient’s computed tomography images. This proposed design has been comparatively investigated with the traditional cemented tibial component by using the finite element analysis. In conclusion, more uniform stress distribution on the tibial trabecular bone related with stress shielding due to long term use was obtained in the patient specific prosthesis. The results have shown that the compatibility |

In conclusion, more uniform stress distribution on the tibialtrabecular bone related with stress shielding due to long term use was obtainedin the patient specific prosthesis. The results have shown that the compatibility between the tibial bone and its component is better than the traditional modeland possibility of loosening failure in the patient specific model is lower. |
