Overview

Brief Summary

The purpose of this study is to monitor the stability of a total hip replacement within the thigh bone when used in artificial hip joints implanted with two different bone cements, Acryloc™ and Palacos® R, in the treatment of patients with hip joint disease requiring a total hip replacement. Patients who enter the study will be randomly allocated to Acryloc™ or Palacos® R and will be evaluated at regular intervals following hip surgery using patient, clinical, x-ray assessments and special x-rays which allow the stability of the hip implant to be determined
