RESUMO

The objective of this study is to analyze the morphometric and morphologic aspects of the femoral intercondylar notch and the femoral condyle in knees of young adult individuals, men and women, by comparing the morphologic characters among genders. 46 simple x-rays of the femoral intercondylar notch of right and left knees taken of 46 individuals, men and women, in the 18 to 35 age bracket without a pathological condition of the lower limbs. The sample was divided into two groups: 46 normal knees of 23 male individuals (group 1, G1) and 46 normal knees of 23 female individuals (group 2, G2). To obtain the radiographic images, the individuals were positioned in genuflection on the examination table with the hands and the knees supported on the table. The articular amplitude of the knees was fixed in 75Â and determined by a clinical goniometer. The radiographic images were digitized through a scanner with help from an illumination chamber and reference lines for measurement were drawn. For better viewing of the limits of the intercondylar notch, clicks with mouse were done demarcating the area with 10 to 20 points. The variables were measured through software KEYCAD complete version 1.0Â (1993). Initially the right and left knees in each group were compared, statistically significant differences were not found in the analyzed variables. The comparative analysis of lbc in relation to laterality and in relation to gender, showed that the masculine values (R= 82.17mm, L=82.13mm, p<0. 05) overlapped into feminine values (R=70.28mm, L=69.82mm, p<0. 05) on both sides. There were no statistically significant differences in if among the groups analyzed in relation to gender(p=0.177), only on the left side (G1=25.76mm, G2=21.88mm, p<0.05). For B variable significantly greater masculine values both in comparative analysis in relation to laterality (R=25.93mm, E=25.60mm, p<0.05) and between genders (G1=25.76mm, G2=21.88mm, p<0.05). In comparison between genders, the variable was significantly greatest in the masculine sex (22.2mm, p<0.05), in relation to laterality there was statistic difference only in the left side (G1=22.72mm, G2=19.63mm, p<0.05). The masculine sex (lcl=29.76mm, lcm=24.92mm, p<0.05), presented wider femoral condyles than feminine sex (lcl=23.59mm, 24.92mm,p<0.05), independent of the side. There was no statistic significance (p=0.150) in analyze of af between analyzed groups in relation to laterality and gender. The masculine sex (0.3074) presented superior values for AÂ (R=72.16Â, L=71.91Â, p<0.05) independent f the side. A bigger percentage of femoral intercondylar notch of conic shape (70.6%), followed for the circular shape (19.6%) and rectangular shape(9.8%), in both genders and sides was observed in this study. The observation of the results of this study leads to the conclusion that there is no morphometric difference between the right and left knees of the same individual and that the gender is the variation factor of the distal epiphysis of the femur in relation to femoral intercondylar notch and to the femoral condyles. The presented data offer comparison parameters to further studies involving knees with A.C.L injury
