Abstract


The purpose of research people tibial plateau morphology, the people knee tibial plateau osteotomy surface anatomy parameters, explore the significance of this prosthesis design. Methods Joint Surgery hospitalized in Shanghai Sixth People's Hospital from March 2005 to August 2006, 168 cases of 206 pathological knee, are the initial line of total knee arthroplasty, intraoperative and postoperative tibial plateau directly The related parameter measurement. 7.0 statistical software for the measured data input SARS analysis calculated the mean and standard deviation, given the correlation coefficient of the tibial plateau outside of the anteroposterior diameter of the tibial plateau width, given the regression equation. Results all 206 knee are entering the analysis of the results. Establish a proportional relationship between the various parameters after osteotomy of the tibial plateau, the result is divided into A, B group, C group the patient's height, the regression equation. Of the parameters of the three groups showed no gender differences (P gt; 0.05), statistically the left and right knee difference (P gt; 0.05). Group A, before and after the medial tibial plateau there is a linear relationship (P lt; 0.05), the correlation coefficient: 0.8246, regression equation: DMTP = -11.8702 0.8341WTP; of anteroposterior diameter DLTP in lateral tibial plateau and tibial diameter DMTP tibial plateau width WTP The platform width WTP there is a linear relationship (P lt; 0.05), the correlation coefficient: 0.8478, regression equation: DLTP = -10.6513 0.7197WTP. Group B, before and after the medial tibial plateau there is a linear relationship (P lt; 0.05), the correlation coefficient: 0.8062, regression equation: DMTP = -11.9522 0.8341WTP; of anteroposterior diameter DLTP in lateral tibial plateau and tibial diameter DMTP tibial plateau width WTP The platform width WTP there is a linear relationship (P lt; 0.05), the correlation coefficient: 0.8078, regression equation: DLTP = -11.6233 0.7992WTP. Group C, before and after the medial tibial plateau there is a linear relationship (P lt; 0.05), the correlation coefficient: 0.7234, regression equation: DMTP = -12.2436 0.8298WTP; of anteroposterior diameter DLTP in lateral tibial plateau and tibial diameter DMTP tibial plateau width WTP The platform width WTP there is a linear relationship (P lt; 0.05), the correlation coefficient: 0.7529, regression equation: DLTP = -10.7347 0.7289WTP. The tibial osteotomy surface transverse diameter / anteroposterior diameter ratio (ML / AP): A group of 1.62-1.81, B group 1.56-1.77 C 1.52-1.74 ML / AP were greater than the the same size imported prosthesis proportion. Conclusions In this study, measurement and statistics people morbid knee tibial plateau morphology size, draw people tibial plateau osteotomy surface transverse diameter and anteroposterior diameter ratio greater than Westerners, the dwarf Chinese women more obvious. People morbid knee tibial plateau relevant parameters reference value, total knee prosthesis design, production people anatomical structure more in line with scientific evidence and the reference value.
