title: Revision of the acetabulum with a contemporary cementless component.
abstract: We evaluated the performance of a contemporary cementless acetabular component at a minimum of 5 years postoperatively. One hundred eighty-seven consecutive acetabular component revisions were performed using a hemispherical porous-coated component. Patients were followed prospectively with radiographs and Harris hip scores. Twenty patients died, leaving 158 patients (166 hips) available for follow-up at a mean of 91 months. No patients were lost. Eleven acetabular components (7%) required repeated revision, including 4 (2%) for aseptic loosening. Seven of the 145 unrevised acetabular components with radiographic follow-up (5%) were loose. The results of acetabular revision with this contemporary acetabular component were good but inferior to those of earlier-generation implants. This difference is likely multifactorial.
