History of Changes
  Purpose

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 Intervention
Osteoarthritis
 Device: Bi-Metric femoral implant (titanium versus cobalt-chromium)

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Treatment
