摘要
[目的]评价计算机导航全膝关节置换系统的初步临床应用结果。[方法]将本科近期在计算机导航全膝关节置换系统辅助下的手术结果与既往的配对病例的术后X线资料进行比较。[结果]计算机术中导航能明显优化假体的位置,极大地减少假体放置的失误率;明显改善力学对线的准确性。[结论]计算机导航全膝关节置换系统能显著地提高假体置入的准确性和全膝关节置换的可重复性。
[ Objective] To evaluate the initial effect of the computer-assisted total knee replacement system. [ Method] The 24 computer-navigated knees in our department were involved, and were matched at ratio of 1： 3 by previous cases at sex, age and disease. All case＇s anteroposterior and lateral projection X-ray films were checked postoperatively. We compared α and β angles at anteroposterior films, γand δ angles ant lateral films of all involved cases [ Result ] Although there was no significant differences existing between two groups, we still observed the obvious reduce risk of malplacement both for femoral and tibial prosthesis, and improvement of mechanical alignment. [ Conclusion] By using computer-navigated total knee replacement system during operating, the precise and repeatability could be ensured.
