Summary

The aim of this study is to further investigate the clinical and radiological importance of design changes in cementless hip prosthesis. The investigators have earlier evaluated the classical Furlong HAC total hip prosthesis and a first design change Furlong Active. Now a further development, Furlong Evolution, is to be evaluated. This prosthesis, furthermore, comes with and without a collar, and the investigators are going to randomize between the two. The investigators hypothesize that the new design will be easier to implant and will present equal or less migration than the older designs which would imply a favourable outcome in the long term. The investigators further hypothesize that the collar play no major part for the long term migration and bone remodelling.

We will now do a 10 year follow up of the patients including RSA, DXA and PROMS

Conditions

  • Hip Replacement in Osteoarthritis Patients

Interventions

PROCEDURE

Stem collar

The stem has two versions, one with and one without a collar. The classical Furlong HAC had a collar.
