Dynamic Analysis of Hip Prosthesis Using Different Biocompatible Alloys

Abstract In the present paper, a three-dimensional finite element model of Charnley implant has been developed to analyze stress–strain distribution and deformation over stem prosthesis. Patient-specific dynamic forces have considered for analytical evaluation using commercial code. The impact each activity analyzed separately six different biocompatible alloy materials made titanium cobalt-chromium. Mechanical parameters evaluated envisage longevity functionality implant. performance suitable gait pattern is Consequently, Cobalt chromium alloys (CoCrMo alloy) demonstrate better results, i.e., maximum stress, minimum deformation, strain as compared with other materials. Every motion, viz., walking, standing up, sitting down, going upstairs, downstairs are found in good agreement safety factor every biomaterial. Additionally, down motion exhibits level, respectively. Based on outcome presurgical study, it recommended that CoCrMo should be preferred
