Abstract
This was a prospective consecutive, study of 50 patients (mean age 72 years, 56% males) treated unilaterally for primary osteoarthrosis using the uncemented, isoelastic, monoblock RM Pressfit Cup. Migration and wear were assessed using the EBRA (Ein-Bild-Röntgen-Analyse) software (201 radiographs from 36 patients). Mean migration was 0.82 mm after 2 years and 1.25 mm after 5 years. A decreasing migration rate over the period was observed. The mean annual wear rate was 0.09 mm/y. Five years after surgery, 84% of patients reached good or excellent Harris hip score values. No revisions related to the acetabular component were necessary. All cups appeared to have high primary stability.
