  Purpose

A randomised, comparative, prospective, single-blinded trial of two hip prosthesis:

  1. Marathon cemented all-poly acetabular cup(Depuy, Warsaw, Indiana), Corail uncemented femoral stem(Depuy, Warsaw, Indiana), 32mm Alumina Biolox Forte femoral head(Depuy, Warsaw, Indiana) and
  2. Pinnacle/Marathon uncemented cup(Depuy, Warsaw, Indiana), Corail uncemented femoral stem(Depuy, Warsaw, Indiana), 32mm Alumina Biolox Forte femoral head(Depuy, Warsaw, Indiana)

There will be a further in-group randomisation to a Corail femoral stem with or without a collar, creating a number of 4 study-groups in total.

The aims of the study are:

  • To compare polyethylene wear and migration of the moderately cross-linked Marathon polyethylene in a cemented version(Marathon) and in an uncemented cup(Pinnacle/Marathon)
  • To evaluate micromigration and periacetabular bone mineral density of the 2 cups using radiostereometry(RSA)
  • To evaluate the migration patterns and proximal femoral bone density changes around the Corail stems with and without a collar

Official Title: Cemented Marathon/Corail Versus Pinnacle/Corail. Comparison of Polyethylene Wear, Component Migration and Periprosthetic Bone Mineral Density. A Randomised Study of 48 Hips Using Radiostereometry and Dual-energy X-ray Absorptiometry

Further study details as provided by Haukeland University Hospital:

Primary Outcome Measures:
  • Polyethylene wear [ Time Frame: After 5 years of follow-up ]
    Comparison of polyethylene wear rates in a modular uncemented acetabular component and a cemented all-polyethylene acetabular component using radiostereometric analysis

  • Component migration-cup [ Time Frame: After 5 years of follow-up ]
    Comparison of the migration of a modular uncemented acetabular component and a cemented all-polyethylene acetabular component using radiostereometric analysis.

  • Periprosthetic bone mineral density [ Time Frame: After 2 years of follow-up ]
    Differences in bone mineral density around a cemented and an uncemented acetabular component using Dual X-ray absorptiometry. Differences in bone mineral density around an uncemented fully HA-coated femoral component with or without a collar using Dual X-ray absorptiometry.

  • Component migration-stem [ Time Frame: After 5 years of follow-up ]
    Comparison of the migration of an uncemented fully HA-coated femoral component with and without a collar using radiostereometric analysis.


Secondary Outcome Measures:
  • Clinical outcome [ Time Frame: After 5 years of follow-up ]
    Comparison of clinical results between study groups using HHS and PROMs
