Objective To obtain the normal linear parameters on the different resection levels of normal proximal tibia in Chinese, and provide reference for improving the design of domestic knee prosthesis and clinic technology of TKA. Method Choose 61 normal Chinese (100 knees, include 65 male and 35 female knees), with average age of 47.2 years (range from 1 7 to 81 year-old), Then divided them into groups according to the age, side of the knee and gender. Utilized original CT image data to set up the three-dimensional model of Chinese normal knees and measure the related linear parameters of different proximal tibia sections on the work station. Result The average anterior-posterior (AP) and medial-lateral (ML) lengths of the proximal tibia section were 48.9±3.1 and 75.2±4.5mm, respectively; the ratio of anterior- posterior (AP) and medial-lateral (ML) was 0.650±0.034. the average anterior-posterior dimensions through the spots with 10, 20 and 30% were 36.1, 46.6, 51.2, 37.1, 44.1 and 47.6 mm, respectively; It is confirmed through statistics analysis that the length of AP and the ratio of AP/ML shows statistics significance among different gender and resection level. Conclusion The geometry and anatomy of proximal tibia in Chinese shows significant differences comparing with westerner; the characteristics and the gender difference should be considered when we use the tibial plateau prosthesis designed by the westerner; the sex difference should also be taken into account when we design the domestic tibial plateau prosthesis and total knee arthroplasty.
