Two-Dimensional Finite Element Analysis for Investigating Stresses Developed in Cement and Bone Layers in Total Knee Replacement

Article Preview

Abstract:

When a patient is undergoing a total knee arthroplasty, the proximal tibia is cut with a certain depth for tibial tray mounting. Moreover, the proximal tibia plateau is then drilled distally to create a hole where the tibial tray stem is inserted. Due to the existence of tibial tray stem stuck into the central part of the proximal tibia, the development of stress around the stem becomes the interesting parameter to be investigated, especially in the cement. For this purpose, a simplified two-dimensional finite element model has been created. The focus of the result analysis was fixed only on the knee bend activity load due to the highest von Mises stress occurred in this activity. The highest von Mises stress of 52.80 MPa occurred in the tibial tray, and then followed by the cortical bone, cement, central cancellous bone, and edge cancellous bone with von Mises stresses were 34.56, 5.40, 1.41, and 1.26 MPa, respectively. In the field of displacement and true strain in the cement, the highest resultant of displacement of 0.2mm occurred in the top section of the cement. Around the posterior tip, the cement experienced the tensile strain of 0.02 and around the anterior tip the strain was the compressive strain with similar value.
