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.
本研究的目的是评估性别特异性或形态特异性全膝关节假体如何改善中国人群股骨远端的假体适配性。数据显示，与标准假体相比，使用性别特异性（Nexgen-LPS GSF，捷迈公司）或形态特异性（Advance Stature Knee，莱特医疗技术公司）膝关节假体时，男性和女性受试者股骨部件的完美适配率均显著提高。当标准假体以及相应的性别或形态特异性膝关节假体均可选择时，股骨部件的完美适配率最高。此外，女性选择性别或形态特异性假体的比例显著高于男性。
