Development of 3D Model of Tibia Femoral Bone in Knee Joint for FEA

Abstract

Tibia femoral bone is a part of knee joint which is a very complex joint of the human body. Now a days knee pain is most frequently observed problem in elderly people. Worldwide statistics reveals about 100 million people experience knee pain hence analysis of knee is very essential for diagnosis and treatment. The change in mechanical properties of knee joint lead to knee bone fracture. Loading of the knee bone and possible fracture can be analyzed using finite element analysis(FEA). The FEA technique used for analyzing mechanical properties of complex knee bone structure which needs 3D model of knee joint bone. This work mainly focuses on segmentation and 3D rendering of tibia femoral bone from MRI/CT scan data using image processing techniques. Interactive segmentation technique is used for segmentation of tibia femoral bones. Using thesegmented images 3D volume rendering is done and 3D model of tibia femoral bone is developed. Finite element meshing technique is carried out on 3D model of tibia femoral bone to create meshed model and the developed model can be used for analysis of force during loading using finite element analysis. The developed interactive segmentation technique along with 3D model creation of bone is useful in analysis and surgery planning.
