The design process of a human knee cap model is presented in this work. Arthritis is the breakdown of the cartilage that lines the ends of the tibia and femur inside the knee joint, often known as the knee cap. This produces discomfort in the knee cap, prompting the replacement of the prosthetic components. In addition to being biocompatible, the prosthetic joints must fulfil and meet specific design standards. Insertion of these joints in humans should not cause too much pain or need too much postoperative care. Furthermore, the longevity and performance of the artificial caps are critical considerations. The severity of the produced stresses at the interface is determined by various parameters, including sagittal radius flexion angles, materials employed for tibia femoral components, and the load operating on the joint and cap bearing surfaces. To guarantee a decrease in stress intensity, it is essential to optimise the design of the prosthetic knee cap while taking the aforementioned parameters into account. In this context, FEM, the most powerful and commonly recognised numerical method for predicting stress state, is increasingly gaining relevance in the optimization of knee cap model design. In view of the above, this work examines the modelling and finite element analysis of a prosthetic knee cap model. |
