Selection application of material to be used in hip prosthesis production with analytic hierarchy process

Abstract

Metallic biomaterials used in making hip prosthesis are required to meet expectations in terms of fatigue strength, corrosion resistance, wear resistance, cost and biocompatibility. It is also desirable that the modulus of elasticity they possess is close to the level of the possible bone. Metallic biomaterials face the problem of ion release even though they meet the criteria mentioned above. As a result, the choice of metallic material to be preferred in the manufacture of hip prosthesis can be made by evaluating all these criteria among themselves and by the performances of biomaterials to be compared according to these criteria. In this study, firstly the criteria expected from the metals to be used as biomaterials have been determined. Expert opinions about the subject and criteria determined in accordance with the studies in the literature by using analytical hierarchy process have been graded according to each other. Afterwards, selection of the most appropriate material was ensured by making the order of importance according to the criteria of the candidate materials.

Material selection and long-term maintenance strategy of knee and hip prosthesis

“…Published by Francis Academic Press, UK -9-because of their superior mechanical properties and biocompatibility [4][5][6] . Titanium alloy is widely used in the field of joint prosthesis because of its light weight, high strength and biocompatibility.…”

“…Some investigators and researchers introduce different methods for the selection of material. These include the Analytic Hierarchy Process (AHP) [25], AHP integrated VIKOR method (Vise Kriterijumska Optimizacija Kompromisno Resenjemeaning) [26], also, the MULTIMOORA or Multi-Objective Optimization Based On Ratio Analysis [27]. However, none of them takes into account an easyto-understand explicit math of the femur.…”

Selection of Ti Alloys for Bio‐Implants: An Application of the Ashby Approach with Conflicting Objectives

“…[ 22 ] Jahan and Bahraminasab used an extended version of TOPSIS, a technique to rank ideal solutions, to evaluate the performance of more sophisticated functionally graded designs of TKR prostheses [ 23 ] and Eroğlu applied an analytic hierarchy process to rank appropriate metals for hip prosthesis based on expert opinions on the subject, which determined the weight of decisive factors in the optimal choice. [ 24 ] Finally, Ristić et al developed an expert system to rank candidates for missing bone parts based on text queries. [ 25 ] Although valuable, these approaches are very restricted from the alloy optimization standpoint, with hardly any design‐free variables.…”
