Abstract

PURPOSE: To evaluate the anatomical configuration of the lateral tibial condyle using the MR axial images and to present the proper configuration of the head of the buttress plate that fit the lateral tibial condyle of Korean
MATERIALS AND METHODS
With 110 MR axial images of the knee joint of male and female, we calculate the ratio of the maximal height of the arc of the l ateral tibial condyle to the length of the line between the end point of the arc of the lateral tibial condyle(the ratio of convexity) and the angle of the peak point of arc of the lateral tibial condyle(the angle of convexity), the absolute value of the difference of the angle of the end point of the arc(the value of symmetry) of that. then we evaluate the head of 3 the buttress plates with same methods and then compare with the result of the lateral tibial condyle.
RESULTS
The ratio and angle of convexity of Korean were average 0.216/49.04(total), 0.203/49.35(male), 0.235/50.36(female), and the value of symmetry were average 5.68(total), 5.76(male), 5.56(female). the ratio and angle of convexity of the head of buttress plate were average 0.177/43.21(EGIRE), 0.114/25(AO), 0.101/23.83(Solco) and the value of the symmetry were 1.643(EGIRE), 0.75(AO), 1.5(Solco). the ratio of convexity was correlated with age, height, and weight but angle of convexity was not correlated with weight.
CONCLUSION
The anatomical configuration of the lateral tibial condyle of Korean did not fit that of the head of the buttress plates and it would be necessary to make a new plate that fit the lateral tibial condyle for Korean.
