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 long lif...
