Abstract:
[Objective]To obtain the normal linear parameters of different resection levels of normal proximal tibia in Chinese people, and discuss the influence of the gender and resection level on the design of the tibia prosthesis. [Methods]Thirty-six normal Chinese people (36 left knees, 18 males and 18 females), with an average age of 43 years (range 18～55 years) were enrolled in this study.Original CT image data were used to set up three-dimensional model of Chinese normal knees.The related linear parameters of different proximal tibia sections were measured and compared.[Results]Parameters of mediolateral (ML) ,medial and latera anteroposteriordimensions(MAP/ LAP) and the aspect ratio(AP/ML) of the resect proximal tibia surface were obtained. The parameters were confirmed by statistics analysis.[Conclusion]The geometry and anatomy of the knee in Chinese people have significant differences from the western people.The prosthesis designed by western people should be choosen carefully.Sex and resection levels should be taken into account in designing tibia prosthesis and or choosing the imported prosthesis in the total knee arthroplasty.
