Recently, gender-specific designs of total knee replacement have been developed to accommodate anatomical differences between males and females. We examined a group male female distal femora matched for age height, determine if there was difference in the aspect ratio (mediolateral distance versus anteroposterior distance) height anterior flange genders. The Hamann-Todd Collection provided 1207 skeletally mature cadaver femora. femoral length, lateral medial flanges mediolateral width were measured all specimens. mechanical axis femur, cut articular assessed. Statistical analysis effect gender upon undertaken, controlling age, race. mean 1.21 (sd 0.07) it 1.16 0.06) (p < 0.001).

Future work design prostheses should take into account overall variability anatomy femur.
