In this study, the 3D reconstruction of a healthy knee joint from an MRI scan is carried out to determine the stresses in the knee joint using finite element analysis. The process of reconstruction involves identifying and segmenting the components of the knee joint, such as bones, articular cartilages, menisci and ligaments from MRI. This is followed by smoothing and wrapping the components, performing volumetric mesh and finite element analysis. Accurate 3D models of components of the knee joint are reconstructed and assembled in ANSYS Workbench. A force of 1150 N corresponding to the gait cycle for the full extension position was applied on the top surface of the femur. The maximum compressive stress and Von Mises stress distributions were determined in the different components of the knee joint. The results of this study indicated that the high load bearing area was located on the posterior portion of the cartilages. It was also observed that the medial meniscus was more likely to rupture as the stresses in the medial meniscus was more than the lateral meniscus.
