A validated finite element study of stress shielding in a ...
Abstract . This study (1) proposes a hybrid knee implant design to improve stress transfer to bone tissue in the distal femur by modifying a conventional femoral implant to include a layer of carbon fibre reinforced polyamide 12, and (2) develops a finite element model of the prosthetic knee joint, validated by comparison with a parallel experimental study....
A total knee prosthesis CAD design | Semantic Scholar
The main topic treated in this paper is represented by the design of a total knee prosthesis in order to obtain a customized product for specific pathological cases (overweight, particular anatomical conformation for knee etc.). In such cases, given the complexity of geometric shape that has any tri-compartmental knee prosthesis and the particularity of individual dimensions of components, the ...
Design of a Free-Floating Polycarbonate-Urethane Meniscal ...
We present a computational-experimental approach for the design optimization of a free-floating polycarbonate-urethane (PCU) meniscal implant. Validated 3D finite element (FE) models of the knee and PCU-based implant were analyzed under physiological loads.
 Comparison of Cementless and Hybrid Cemented Total Knee ...
arly condylar total knee arthroplasty (TKA) implant designs most com-monly used an all-polyethylene ce-mented tibial component.1-3 Since the mid 1980s, modular, metal-backed tibial trays have dominated the TKA implant market based on finite-element analysis studies that reported superior force distribution compared with conventional all-polyeth-...
Novel adaptive finite element algorithms to predict bone ...
These new Finite Element algorithms show that using implant materials with lower elastic modulus, osteoconductive coatings or improved implant design could lead to increased bone remodelling that optimises tissue regeneration, fulfilling the potential of enhanced porosity and complex implant designs made possible by additive layer manufacturing ......
1. Introduction
Finite element analysis has been performed to evaluate and analyze the potential of the proposed design concept. In the case of the hybrid implant, numerical results have shown that the von Mises stresses were more uniform and higher by more than 15% in the cancellous bone.
High congruency MB insert design: stabilizing knee joint ...
PCL management and choice of insert design and mobility in total knee arthroplasty are still debated in the literature. Consequently, the purpose of this study was to analyze the biomechanics of a fixed and a mobile bearing total knee arthroplasty with conventional and ultra-congruent insert during walking and squat activities, using finite element analysis, and to check the performance in a ......
Physiological joint line total knee arthroplasty designs ...
Finite element calculations were conducted to analyse the stresses in the PE-Inlay and the mechanical strains at the bone side of the tibia component-tibia bone interface during normal positioning of the components and internal and external mal-rotation of the tibial component. Two designs were included, a horizontal and a physiological implant.
