  Background & Aim: Normal axial alignment restoration in lower extremities is very important for surgeons that perform reconstructive surgeries. Since normal values of axial alignment in Iranian population aren't available, normal values in western countries are used in practice.

  In this study axial alignment norms in Iranian adults were determined and the results were compared with those of the studies in China and America.

  Patients and Method: Through a cross-sectional design, axial alignment view of lower extremities was taken in 68 volunteers (34 males & 34 females) between 18 and 32 years old. The. average of axial alignment angles was measured. Data analysis was done by t-test and the existence of correlation was examined by using SPSS software. Then the results were compared to those obtained by the studies in China and America.

  Results: The average angle between anatomical axis of femur and tibia was 5. 10 ,which was different from 60 in western countries studies.

  Medial proximal tibial angle was 86. 30 ,which was different from Chinese and American studies.

  The angle between mechanical axis of femur and tibia was 178. 50,which was not different from past studies. Tibia, in this study, had 0. 9 degrees tibia vara. and ankle was of 1. 7 degrees in valgus.

  Conclusion: Lower extremity axial alignment angles in Iranian adults are different from those in Chinese and American adults. Based on the angle between anatomical axis of tibia and femur, women's knee has 1. 60 more valgus than men's. No correlation was found between axial alignment and height, weight, tibia and femur length.
