Brief Summary:
In this randomised study, the migration of a specific cemented titanium femoral stem will be compared with a similar cemented cobalt-chromium stem using Roentgen stereogrammetric analysis (RSA). In addition, the periprosthetic bone mineral density (BMD) will be evaluated to point out any interference from the modulus of the stem investigated.

Condition or disease Intervention/treatment
Osteoarthritis Device: Bi-Metric femoral implant (titanium versus cobalt-chromium)

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 40 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Comparison Between Titanium Femoral Stem and Cobalt-Chromium Femoral Stem in Cemented Hip Arthroplasty. A Randomized Prospective Roentgen Stereogrammetric Analysis.
