How the Gender or Morphological Specific TKA Prosthesis Improves the Component Fit in the Chinese Population?

Abstract The purpose of this study was to evaluate how the gender specific or morphological specific total knee prostheses improve the component fit in the distal femur of the Chinese population. The data showed that the perfect fit rate of the femoral component remarkably increased in both the male...

Description
Summary:Abstract The purpose of this study was to evaluate how the gender specific or morphological specific total knee prostheses improve the component fit in the distal femur of the Chinese population. The data showed that the perfect fit rate of the femoral component remarkably increased in both the male and female subjects when using the gender specific (Nexgen-LPS GSF, Zimmer) or morphological specific (Advance Stature Knee, Wright Medical Technology) knee prostheses, compared to their standard counterparts. The highest femoral component perfect fit rate was achieved when both the standard and the corresponding gender or morphological specific knee prostheses were available for selection. Additionally, the percentage of the gender or morphological specific prosthesis selection in the females was significantly higher than the males.
