Abstract
Twenty five hips involving 25 patients with Harris-Galante cementless THA were examined with a mean follow-up period of 6.5 years. They were evaluated both clinically and radiologically. The result of the JOA hip score ranged from 64 to 97 points with an average of 86 points, and thigh pain was observed in 7 hips. Radiological findings such as socket migration, osteolysis, loosening were not observed in the acetabular component. Stem sinking was seen in 2 hips, one of which showed definite loosening. Focal osteolysis occurred at zone 1 and 7 in one hip, while cortical hypertrophy was seen in 6 hips (24%) and occurred mainly in zone 2 and 6. Reactive line which indicates linear ossification around the components was observed in the socket of 8 hips (32%) and the stem of 25 hips (100%). The reactive line around the stem occurred with more than 90% of incidence at zone 1 and 4, showing a low incidence at zone 7 which contains a porous coating of the stem.
