Wear particles produced during articulating artificial joints contribute to aseptic loosening. The biomaterials used to manufacture the artificial joints have different wear rates and liberate particles of different size and different biological reactivity. The main goal of this work was to compare the results of isolation of wear polyethylene particles from periprosthetic tissues with histological results of two groups of implants. Two groups of implants were examined; in both, the femoral stem was made of Ti6Al4V alloy, and the acetabular component was made of polyethylene. Implants differed in the material of femoral head, which was stainless steel or ceramic (Al2O3).
