Morphologic Differences of the Distal Femur between Caucasian and Japanese Women

Purpose. To compare the morphology of the distal femur between Caucasian and Japanese women. Methods. 30 Caucasian women aged 41 to 84 (mean, 67) years and 70 Japanese women aged 54 to 86 (mean, 70) years who underwent total knee arthroplasty for osteoarthritis were randomly selected. Morphologic measurements of the distal femur were compared using lateral radiographs. Both race and height influenced the morphology. To adjust for the influence of height on morphology, each measurement was divided by the patient's height and the ratios were compared. Results. Caucasian women were generally taller and heavier (p
