What is Wear particle diffusion and tissue differentiation in TKA implant fibrous interfaces about?
In the context of mechanical loosening, we studied the hypothesis that wear-particle migration in the "brous membrane under tibial plateaus after total knee arthroplasty can be explained by the pumping e!ects of the interstitial #uid in the tissue. Further, as a secondary objective we investigated the possibility that interface-tissue di!erentiation is in#uenced by interstitial #uid #ow and strain, as mechanical e!ects of interface motions. For comparative reasons, we analyzed a previously published simpli"ed twodimensional "nite-element model, this time assuming biphasic tissue properties. We wanted to determine hydrostatic pressure and #ow velocities in the #uid phase, in addition to stresses and strains, for time-dependent loading of the plateau. We found that #uid #ow in the interface was extremely slow, except in the periphery. Hence, loosening due to particle-induced bone resorption appears improbable. The results, however, do support the idea that particles migrate with #uid #ow, when such #ow occurs. Where "brous tissue tends to be prominent in reality, the #uid is repeatedly extruded and reabsorbed in the model. Where these values are low, "brocartilage is commonly found.
