In order to investigate this problem, several sets of in vivo polyethylene wear particles were isolated without centrifugation in the same way. The spontaneous flotation and three different centrifugation speeds were used in the final isolation step. The morphology of the wear particles was assessed by image analysis of SEM micrographs. Centrifugation speeds up to 105,000 g had no effect on observed parameters of the wear particles.
