ABSTRACT: Purpose: To restore the normal axial alignment of the lower extremity is important in reconstructive knee surgery. The aim of this study was to evaluate lower-limb alignment and posterior tibial slope. Methods: Thirty-two male and 32 female outpatients aged 22 to 46 were recruited. A full weight-bearing anteroposterior radiograph of the entire lower limb was obtained for each subject. The axial alignment was measured based on the centers of the femoral head, knee, and ankle. The tibiofemoral (TF), tibial joint (TJ), and posterior tibial slope (TS) angles were determined. Results: The mean TF angle was more varus in women (177.8°) than men (179.2°), and the mean TJ angle was more medially inclined in women than men. Women had a greater TJ angle than men (93.3° vs. 91.6°). The mean posterior TS was greater in men than women (16.0° vs. 12.5°, p
