متن کاملFive-year comparison of oxidized zirconium and cobalt-chromium femoral components in total knee arthroplasty: a randomized controlled trial.
BACKGROUND In vitro analysis has shown that oxidized zirconium on ultra-high molecular weight polyethylene has better wear properties than cobalt-chromium on ultra-high molecular weight polyethylene. The purpose of this study was to determine if oxidized zirconium femoral components performed better than cobalt-chromium in vivo and if the use of oxidized zirconium components had clinical advers...
متن کاملDifferences in metal ion release following cobalt-chromium and oxidized zirconium total knee arthroplasty.
Ions are released from all metals after implantation in the body through processes of corrosive and mechanical wear. The aim of this study was to investigate whether serum metal ion levels are raised in patients following total knee arthroplasty. Serum levels of chromium, cobalt, aluminium, molybdenum and zirconium were measured in two groups of patients at a minimum of 3 years after knee arthr...
متن کاملKnee Simulator Protocol for Testing of Oxidized Zirconium and Cobalt Chrome Femoral Components under Abrasive Conditions
INTRODUCTION: Surfaces of retrieved total knee arthroplasty (TKA) femoral components reveal that roughening often occurs in vivo [1,2]. Many scratches have plowed-up adjacent peaks often with some crosshatching, and appear to be created by abrasive particles, such as bone cement, metal, or bone debris. In vitro studies have shown that scratches, particularly those at an angle to the direction o...
متن کاملMetal sensitivity in patients before and after total knee arthroplasty (TKA): comparison between ceramic surfaced oxidized zirconium and cobalt-chromium implants
Backgrounds: The purpose of this study was to investigate clinical relevance of preoperative screening for metal sensitivity (MS), and to assess whether there is any difference in the MS after total knee arthroplasty (TKA) between oxidized zirconium (OxZr) and cobalt-chrome (Co-Cr) implants. Methods: A total of 48 subjects referred for TKA were enrolled the study with no history of metal allerg...
