The purposes of this study are to evaluate the clinical and radiological results of Harris Galante porous acetabular cup and to compare the results according to the fixation methods. In cementless total hip arthroplasty using Anatomic stems and Harris-Galante Porous acetabular components, 32 acetabular cups inserted line to line with several screws(Group I) and 21 acetabular cups fixated press fit without screws(Group II) were compared. The follow-up period was between 2 years and 4 years(average, 38 months). The mean Harris hip score at final follow-up was 88.7 for group I and 94.4 for group II(p=0.018). Initial gaps were present in nine hips(28%) of Group I and six hips(29%) of Group II. New radiolucencies on the 2-year follow-up radiograph were identified in group I(eight in zone I, four in zone II, and three in zone III), but there were no new radiolucencies developed in group II. Radiolucent lines at final follow-up were seen in nine hips(28%) of Group I, but there was no radiolucencies in Group II. This study demonstrates excellent clinical and radiographic performance of HGP acetabular components at 2-4 years in primary THA. The press-fit fixation could eliminate the problems associated with use of the screws. The clinical and radiologcial results have shown press fit group to be superior to the line to line fixation group using screw.
