Polyethylene wear is one of the most important problems of total hip arthroplasty. We reported 10 cases of revision THA because of large bone absorption of acetabulum due to osteolysis. The patients underwent initial THA with the Kyocera Perfix between January 1997 and January 2000. The liners were not made of cross-linked polyethylene. The patients were 3 men and 7 women with an average age at operation of 66 years (range, 45 -80 years). The average period from the initial THA to the revision was 74 months (range, 45 -91 months). The results showed that liner wear rates were 0.28 mm/year and 107.5 mm3/year. The acetabular component had significantly high clinical wear rates. Care must be taken to avoid osteolysis and to avoid revision THA.
