The subject of this research consists of determining the status of lower extremities of primary school population, as well as frequency of disorders of the lower extremities in the knee joint ('X' and 'O' legs). The aim was to determine the presence of the mentioned disorders and also to establish connection of the present deformities with age and sex of subjects. The research took samples from students from the first to the eighth grade of elementary school Dragiša Luković - Španac, which is located in the suburb of the city of Kragujevac. The study comprised 651 respondents (310 girls and 341 boys). Identifying the presence of deformities of the lower extremities 'X' and 'O' legs, was carried out using Napoleon Volanski's modified method. The existence and the size of connection between the researched fields was calculated by Pearson's Chisquare test and Coniingency coefficient as a measure of connection based on Chisquare test. By analyzing the total number of respondents (651), we conclude that the deformity 'X' legs is much more widespread (7.53%) than the deformity 'O' legs (4.76%) considering the researched population. The deformity 'X' legs is mostly present in the fifth (11.36%) and in the first grade (10.59%), while it is the least manifested in the sixth (3.57%) and second grade (4.17%). 'O' legs deformity is mostly manifested in the eighth grade with 11.67%, whereas it is not present in the second, fifth, and sixth grade. Deformity 'X' legs is mostly manifested in the eighth grade for boys (10.84%), while for girls in the fourth (17.39%) and in the first grade (14.89%), and the deformity 'O' legs is mostly manifested with boys of the eighth grade (19.28%), while the girls recorded the highest manifestation in the third and eighth grade with about 5%. The value of Pearson's Chi square test of 10.00 and Contingency coefficient of 0.12 with the level of significance of 0.02, indicate a statistically significant differences in the status of lower extremity in the knee joint, depending on the sex of the researched population.
