Early comparison of femoral components in hip arthroplasty. A preliminary study

This study sought to compare five different brands of femoral components used in hip arthroplasty with regard to the quality of results 1 year postoperatively. The five components were Zimmer Pre-coat, Harris-Galante, porous-coated anatomic (PCA), Omnifit microstructured, and Omnifit collared. The same surgeon supervised all cases. Overall, the Pre-coat, Harris-Galante, PCA, and Omnifit microstructured components produced better results than did the Omnifit press-fit collared components. Within this time frame, neither individual patient characteristics nor intraoperative fractures had a statistically significant effect on the results, and there was no correlation with roentgenographic changes.
