Existence of variations in morphological proportions in human beings has led to the development of different values of tibio femoral angle (TFA) in different populations which is undoubtedly useful in clinical orthopaedic surgery. Meagre literature is available among Indian population. The cross-sectional study was creating baseline data of TFA among Rajasthani population of India with reasonable accuracy and also to correlate these data to radiological findings during July 2014-June 2016. The TFA (in degrees) of 500 healthy subjects from various regions of Rajasthan were measured in standing and supine positions. In addition, the TFA of 134 persons (randomly selected) from study group were also measured on roentgenogram. Subsequently both of these data were compared. The normal range of TFA angle in Rajasthani population was in between 160°-174°. TFA in standing position on right side was 170.96° (with 95% Confidence Interval (CI) = 170.24 to 171.68) and on left side was 170.14° (with 95% CI = 169.21 to 171.06). Mean TFA in supine position on right side in age group from 21 to 30 years was 167.12±6.73° and in age group from 31-40 years was 167.668±6.7°. No significant difference was observed in posture change and according to age. Statistically significant difference was observed in between radiological and gross measurement which was more in radiological than to clinical measurement of TFA (mean difference = +5.78° units) with 95% CI for the difference is (4.03°-7.53°). Higher values of tibio-femoral angle (TFA) were observed in males as compared to females and in radiological measurements.
