Introduction.
Overlooked polymethylmethacrylate after unicondylar knee arthroplasty can be a potential problem, since this might influence the generated wear particle size and morphology.
The aim of this study was the analysis of polyethylene wear in a knee wear simulator for changes in size, morphology, and particle number after the addition of third-bodies.
Material and Methods.
Fixed bearing unicondylar knee prostheses (UKA) were tested in a knee simulator for 5.0 million cycles.
Following bone particles were added for 1.5 million cycles, followed by 1.5 million cycles with PMMA particles.
A particle analysis by scanning electron microscopy of the lubricant after the cycles was performed.
Size and morphology of the generated wear were characterized.
Further, the number of particles per 1 million cycles was calculated for each group.
Results.
The particles of all groups were similar in size and shape.
The number of particles in the PMMA group showed 10-fold higher values than in the bone and control group (PMMA: 10.251×1012; bone: 1.145×1012; control: 1.804 × 1012).
Conclusion.
The addition of bone or PMMA particles in terms of a third-body wear results in no change of particle size and morphology.
PMMA third-bodies generated tenfold elevated particle numbers.
This could favor an early aseptic loosening.
