Abstract : Abstract - This study aims to compare the biomechanical characteristicof the tibiofibular contact pressure in the total knee arthroplasty (TKA) between the cruciate retaining-CR and posteriorstabilized-PS type. A three-dimensional finite element (FE) model consisting of the femur and tibial insert components was constructed to analyze using computer-aided engineering software. The bearing load in the vertical direction was performed in a range of 4 to 5 times body weight based on the various flexion angle corresponding to the PI-17 standard loading. The contact stress distribution, including the contact area between TKA, was evaluated and then verified with the mechanical test using the Fujifilm technique. The results showed that the maximum contact pressure ofCR-type TKA ranged from 18.55 MPa to 57.00 MPa, and the contact area was displayed between 275.02mm2 to 602.27 mm2 for the increased flexion angle from 0 to 90 degrees. While the maximum values of contact pressure and contact area ofPS-typeTKA were in the range of 27.69 MPa to 76.88 MPa, and 232.64mm2 to 266.29 mm2, respectively. According to the specific design oftibial insert components, the tibiofibular contact area of CR-type TKA exhibited a higher value than PS-type TKA. The magnitude of contact pressure in the CR-type TKAdisplayed a lowervalue than PS-type according to the increased flexion angle. For the validation, theresults of contact stress and contact area from numerical simulations displayed similar to those of Fujifilm mechanical tests. This study explains the differences in the two types of TKA, which describe the contact mechanism behavior based on the contact knee test.
