Application of a finite element method to predict fatigue life of the knee mobile bearing

Knee Arthroplasty is a surgical procedure where the patient’s knee is replace by prosthesis. By using the finite element analysis method, we can properly estimate the life span of the prosthesis and also the polymer mobile bearing between the prosthesis itself. Most of the prosthesis have a lo...

Application of a finite element method to predict fatigue life of the knee mobile bearing

By using the finite element analysis method, we can properly estimate the life span of the prosthesis and also the polymer mobile bearing between the prosthesis itself. Most of the prosthesis have a long lifespan but not for the polymer mobile bearing. Having only average of 2.5 years lifespan, it is a hustle for the patient to come back every 2.5 years to replace a new polymer especially for the elderlies. This research is made to investigate and predict the fatigue life of the polymer mobile bearing via finite element method and thus to design a newly improved prosthesis model based on the commercially available. In this research, three different designs were made based on the currently available mobile-bearing design.
