Micromotion magnitudes exceeding 150 µm may prevent bone formation and limit fixation
after cementless total knee arthroplasty (TKA). Many factors influence the tray–bone …

Background Cementless tibial baseplates in total knee arthroplasty include fixation features
(eg, pegs, spikes, and keels) to ensure sufficient primary bone-implant stability. While the …

Component alignment in total knee arthroplasty is a determining factor for implant longevity.
Mechanical alignment, which provides balanced load transfer, is the most common …

The initial fixation of cementless tibial trays after total knee arthroplasty is crucial to bony
ingrowth onto the porous surface of the implants, as micromotion magnitudes exceeding 150 …

The initial fixation of cementless tibial trays after total knee arthroplasty is critical to ensure
bony ingrowth and long-term fixation. Various fixed-bearing implant designs that utilize …

Background There has been a recent increase in the use of cementless fixation for primary
total knee arthroplasty. While the early results of contemporary cementless implants are …

Abstract Objectives The cementless Oxford Unicompartmental Knee Replacement (OUKR)
tibial component relies on an interference fit to achieve initial fixation. The behaviour at the …

Cementless total knee arthroplasty (TKA) implants rely on interference fit to achieve initial
stability. However, the optimal interference fit is unknown. This study investigates the effect …

Total knee arthroplasty (TKA) components from a material with stiffness properties similar to
the human bone, such as polyetheretherketone (PEEK), can be used to reduce peri …

Q1: Primary stability of cementless hip and knee replacement implants can be assessed
through analysis of implant-bone interface micromotions. Interface micromotions can be …
