RCT Comparing Ion Levels and Clinical Outcomes of A-Class BFH to Metal on Polyethylene Total Hip Replacement
A Prospective Randomized Clinical Trial Comparing Ion Levels and Clinical Outcomes of the CONSERVE® A-Class Total Hip System With BFH® Technology to Metal on Polyethylene Total Hip Replacement
The primary aim of this study is to demonstrate that blood ion levels (cobalt and chromium) are lower at one year in patients who receive a metal on polyethylene total hip as compared to CONSERVE® A-Class Total Hip with BFH® technology. Secondary aims include the gathering of clinical data regarding survival and dislocation rates at two years post surgery, as well as the assessment of pain, physical function, radiographic and clinical outcome at the two year interval.
