Biomechanical Assessment of Modular Tibial Tray Configurations in Total Knee Arthroplasty

EasyChair Preprint no. 13965

Abstract

Total Knee Arthroplasty (TKA) is a widely performed surgical procedure aimed at alleviating pain
and restoring function in patients with severe knee joint pathologies. The design of tibial trays in
TKA is crucial for the long-term success of the prosthesis. Modular tibial tray configurations offer
the potential for enhanced fit and customization but their biomechanical performance, particularly
under fatigue loading conditions, requires thorough assessment, this study conducts a
biomechanical assessment of various modular tibial tray configurations used in TKA. A series of
experimental tests were performed using cyclic loading to simulate the repetitive stresses
experienced by the knee joint during typical daily activities. Finite Element Analysis (FEA) was
also utilized to model stress distribution and identify potential failure points in the modular
constructs.
The experimental results demonstrated significant differences in fatigue performance among the
modular tibial tray configurations. Specific designs exhibited superior resistance to cyclic loading,
attributed to optimized material selection and geometrical enhancements. FEA results corroborated
the experimental findings, highlighting regions of high stress concentration and potential fatigue
failure, the biomechanical performance of modular tibial tray configurations in TKA varies
significantly based on design and material characteristics. The findings underscore the importance
of careful selection and optimization of modular components to enhance the durability and
longevity of the prosthesis. Further research is recommended to explore additional design
modifications and their impact on fatigue performance.
