Patient Demographics and Average Limb Alignment Values According to Full-Length Weight-Bearing and Anteroposterior Weight-Bearing Knee Radiographs

Demographic	Mean ± SD
Age, years	45 ± 17
Body mass index, kg/m2	26.5 ± 5.1
Gender	62M, 58F
Radiograph technique
Full-length weight-bearing, mechanical axis	178.2 ± 3.8
AP angle 1	180.0 ± 3.6
AP angle 2	182.6 ± 4.0

NOTE. N = 120. Angles were recorded in degrees with respect to neutral alignment at 180°. AP angle 1 and AP angle 2 were the two tibiofemoral angle measurement techniques used on standard AP radiographs.

AP, anteroposterior; F, females; M, males.
