Computational biomechanics of knee joint arthroplasty : a review

抄録

Computational models have been widely used for more than four decades to evaluate the mechanical behavior of knee joint arthroplasty. Validated computational models provide a virtual platform to develop optimal articular surfaces which achieve desired implant characteristics. This review paper provides a comprehensive overview of the computational models available to represent knee joint arthroplasty. A brief overview of knee joint anatomy and arthroplasty is provided, followed by computational model development techniques. Use of the computational models in development of knee joint arthroplasty and pre- or post-clinical evaluation is summarized. This review paper presents current modeling capabilities for implant design and stability, with further suggestions for studying the performance of implants on a population level. However, simulations must include closely corroborated multi-domain analysis in order to account for real-life variability.
