Patients and Methods
The aim of this study was to compare the incidence of aseptic
loosening after the use of a cemented acetabular component and a
Trabecular Metal (TM) acetabular component (Zimmer Inc., Warsaw,
Indiana) at acetabular revision with bone impaction grafting. A total of 42 patients were included in the study. Patients were
randomised to receive an all- polyethylene cemented acetabular component
(n = 19) or a TM component (n = 23). Radiostereometric analysis
and conventional radiographic examinations were performed regularly
up to two years post-operatively or until further revision.Aims
