Aseptic loosening of femoral components - materials engineering and design considerations


Bahraminasab, Marjan and Sahari, Barkawi and Edwards, Kevin L. and Farahmand, Farzam and Arumugam, Manohar (2013) Aseptic loosening of femoral components - materials engineering and design considerations. Materials & Design, 44. pp. 155-163. ISSN 0261-3069


Aseptic loosening is one of the main reasons for the revision of a total knee replacement (TKR). The design of the key component of a TKR, the femoral component, is particularly problematic because its failure can be the result of different causes. This makes the development of new biomaterials for use in the femoral component a challenging task. This paper focuses on the engineering design aspects in order to understand the limitations of current materials and design deficiencies. The paper describes the introduction of a new biomaterial for a femoral component and justifies the recommendation to use multi-functional materials as a possible solution to aseptic loosening. The potential advantages of applying functionally graded biomaterials (FGBMs) in prosthetic femur are explained by reducing the leading causes of failure including wear, micro-motion and stress-shielding effect. The ideas presented in this paper can be used as the basis for further research on the feasibility and advantages of applying FGBM in other superior implant designs.
