Total ankle replacement is a procedure in which an injured ankle joint is replaced with a plastic and metal joint. Available data suggest that total ankle replacement has a relatively short lifespan. Presently SS316L, Ni-Cr Alloys, Ti-6Al-4V are used as implant material in ankle replacement surgery. The materials are conventional material, heavier in density which fails within prescribed period and costly.
The objective of this study is to analyse stresses on implant of the ankle joint. A three-dimensional finite element method (FEM) model of the implant will be developed for the study. The analysis of the FEM model found stress concentrations in the implant. To obtain the results by considering the different loads exerted by human body weight on ankle joint implants while walking, running, jumping.
From the results of analysis on implant, it can be concluded that stainless steel have minimum stresses as compared to alumina but density is heavier considered to Titanium alloy. As metal alloys are heavier in density the bone cannot withstand that. The ankle replacement material requires less deformation and low density. The low density materials are recommended for better life and performance. Developing a new material with low density (PMC) may the future of this work.
