The Polarstem Versus Corail; a Comparison of Micromotion and Periprosthetic Bone Remodelling of Two Femoral Stems. A Randomised Trial of 60 Patients Using Radiostereometric Analysis, Dual Energy X-ray Absorptiometry and Computer Tomography
In Brief
A clinical study evaluating Polarstem and Corail for Arthritis of the Hip. Active but no longer recruiting, targeting 60 participants across 1 site.
Detailed Summary
A randomised controlled trial comparing a recently introduced femoral stem with an established stem for total hip arthroplasty (THA). 60 patients will be randomised into one of the two groups 1. Polarstem uncemented femoral stem (Smith \& Nephew) 2. Corail uncemented femoral stem (De Puy) All patients will receive a 32mm cobalt-chromium (CoCr) femoral head and an R3 acetabular cup with a 10 Mrad highly cross-linked polyethylene (XLPE) liner (Smith \& Nephew). Radiostereometric analysis (RSA) will be used to measure stem migration. Dual-energy x-ray absorptiometry (DXA) measurements will be used to measure bone mineral density. Clinical outcome will be assessed at different time point to evaluate satisfaction and function. Data from the Norwegian Arthroplasty Register will be used to investigate the risk of revision.
