Influence of Modularity on the Fatigue Durability of Tibial Tray Designs in TKA Prostheses

EasyChair Preprint 14328, version 2

Abstract

The influence of modularity on the fatigue durability of tibial tray designs in total knee arthroplasty (TKA) prostheses is a critical consideration in optimizing implant longevity and performance. This study investigates the impact of modularity on the fatigue resistance of four distinct tibial tray designs using a combination of computational modeling and experimental testing. By comparing stress distributions and fatigue life across modular and non-modular designs, we identify key factors affecting the mechanical performance and durability of these implants. Our findings reveal significant differences in stress concentrations and fatigue resistance among the designs, highlighting the importance of modularity in enhancing the longevity of TKA prostheses. The results provide valuable insights for the design and selection of tibial trays, aiming to improve patient outcomes and prosthetic performance.
