Hybrid Versus Cemented TKA Using the NexGen LPS Prosthesis ...
Early total knee arthroplasty (TKA) implant systems most frequently used an all-polyethylene cemented tibial component1. Based on finite-element analysis studies reporting superior force distribution compared with conventional all-polyethylene components, metal-backed tibial baseplates have dominated the TKA implant market since the middle of the 1980's2....
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 ......

Background. Finite element analysis (FEA) has been applied to investigate dental implant designs, the structure and material of the superstructure, and the stability of the surrounding bone [1, 2].According to PubMed, only 10 FEA studies of dental implants were published in 1990, while 102 papers were published in 2014.

The goal of this research is to study the preclinical development and testing of a self-sensing and self-powered total knee replacement (TKR) that embeds piezoelectric transducers inside the polyethylene bearing of a TKR unit for load sensing of tibiofemoral forces and generation of electrical energy to power the device.

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.

Finite Element Analysis of the Proximal Femur and Femoral Component of a Total Hip Replacement The objective of this project is to determine the consequence of the fibrous tissue layer on the stress distribution of the total hip implant system . A realistic element that models the fluid-filled interface tissue has not been developed to date.

bone and implant. Two geometric models were created: an actual 3D representation of the tibia and the respective tibial components (realistic model); and a simplistic model for a better understanding of the interface behaviour. Both models were subjected to a Finite Element Analysis (FEA), varying the slopes in the sagittal
