There are many investigations about the femoral osteolysis including the patterns and size of the lesion. However, the factors, which influence the patterns and size of the femoral osteolysis, are not well known. Purposes of the study were to evaluate the patterns of the femoral osteolysis, to analyze the planimetric and approximate volumetric values of the lesion after cementless total hip arthroplasty and to evaluate the factors, which influence the patterns and size of the femoral osteolysis. We analyzed 120 hips who had undergone cementless THA using Harris Galante pomus prosthesis (Zimmer, Warsaw, Indiana) in 49 hips and Anatomic components (Zimmer, Warsaw, Indiana) in 71 hips. After an average of 4.9 years (range 4-10 years), 45 cases (37.5%) showed femoral osteolysis on the radiograph. The mean rate of linear wear was 0.24+-0.14mm in the cases of the femoral osteolysis. The size of the femoral osteolysis was correlated with duration, stem type, linear wear amount and linear wear rate. The linear wear amount showed higher correlation than the linear wear rate. In this study, the factors which influence the patterns of the femoral osteolysis were not found. Among eight cases of the revision, five cases required the revision due to severe femoral osteolysis lesion and polyethylene liner wear without the loosening of the prosthesis. We could confum that the size of osteolysis is important factor for the result of THA. Therefore, it is necessary to carefully follow-up the patients which show the osteolytic lesion and include the size of osteolysis in the item of the evaluation for the result of THA.
