We undertook this study to determine the average valgus cutting angle of distal femur in South Indian population since most of the studies are on western population and very few studies in Indian population and particularly South Indian population. Methods: We did a study femoral valgus angle of 174 knees in 87 patients with full length CT scannograms in our radiology department. Results: The average Femoral valgus angle was found to be of 6.51 ± 0.76 and there was no statistically significant difference between male and females or between both the sides. There was a strong correlation between the two sides(0.971) and weak correlation with regards to age(.003).
