Abstract

Seventy consecutive primary total hip arthroplasties in which a Harris-Galante porous-coated acetabular component had been used from October, 1986 to December, 1989 were reviewed for 5 to 9 years follow-up. We performed the retrospective, clinical and radiological analysis of the hemispheric, porous-coated, cementless acetabular component using press-fit and screw fixation. No component had detectable migration or any other position change. No acetabular fractures and no screw problems were noted. Initial peripheral gaps were observed in 11 cases (16%). Twelve cases had a postoperative polar gap less than 0.5 mm which were stabilized at 2 years postoperatively. Radiolucent line was present in at least one zone in 53% of cases and occurred most frequently in zones 1 and 3. No continuous radiolucent line greater than 2 mm was seen in any zone and radiolucent lines were stabilized 2-3 years postoperatively. Twelve hips (17.1%) had osteolysis of the acetabulum. No acetabular component was revised because of aseptic loosening. Revision arthroplasties were performed in 9 hips during follow-up. We concluded that the hemispheric porous-coated, acetabular components using press-fit and screw fixation had good results with a 5 to 9-year follow-up.
