Effects of micro-arc oxidation coating on outcomes of a cementless grit-blasted tapered-wedge stem in total hip arthroplasty.
To evaluate the effects of micro-arc oxidation (MAO) coating on the outcomes of a grit-blasted tapered-wedge stem in total hip arthroplasty (THA), we performed a retrospective review of 141 THAs using MAO coated stem for a minimum of 5years and compared them to 219 THAs using the same geometry stem without MAO coating. Harris hip score improved from 43.7 points preoperatively to 93.9 points pos...
متن کاملEarly Cementing Does Not Increase Toughness of Grit Blasted Interfaces
Introduction: Grit blasted stem-cement interfaces have been advocated as a means of increasing the bond strength of the stem-cement interface in cemented total hip arthroplasty. Recent work has suggested that early cementing of rough stem surfaces can increase the bond strength of the interface when compared to the same interface cemented using very doughy cement [1]. Based on these findings, s...
متن کاملSurvival analysis of cementless grit-blasted titanium total hip arthroplasties.
Although about 200000 cementless Zweymüller-Alloclassic total hip arthroplasties (THAs) were carried out worldwide in the last decade, the survival analysis of these prostheses was not available in the 2000 report of the Swedish national hip arthroplasty registry. We report a prospective survivorship analysis of 200 consecutive grit-blasted cementless Alloclassic primary THAs carried out since ...
متن کاملBiomaterial Property Effects on Platelets and Macrophages: An in Vitro Study
The purpose of this study was to evaluate the effects of surface properties of bone implants coated with hydroxyapatite (HA) and β-tricalcium phosphate (β-TCP) on platelets and macrophages upon implant installation and compare them to grit-blasted Ti and Thermanox used as a control. Surface properties were characterized using scanning electron microscopy, profilometry, crystallography, Fourier ...
متن کاملHydroxyapatite-coated versus grit-blasted femoral stems. a prospective, randomised study using EBRA-FCA.
We have carried out a prospective, randomised study designed to compare the long-term stability of the stem of cementless femoral implants with differing surface configurations. A total of 50 hips (46 patients) was randomised into two groups, according to whether the medullary stem had been grit blasted (GB) or coated with hydroxyapatite (HA). Both femoral prostheses were of the same geometrica...
