Gender differences in the morphology of the trochlea and the distal femur

Purpose The objective of this study was to provide a morphologic description of the distal femur and to determine whether there are any gender differences in the shape that might have an important consequence for the design of a femoral component of a total knee prosthesis.

Zusammenfassung:Purpose The objective of this study was to provide a morphologic description of the distal femur and to determine whether there are any gender differences in the shape that might have an important consequence for the design of a femoral component of a total knee prosthesis. Methods Anthropometric data on the distal femur of 200 normal knees were obtained using two-dimensional MRI measurements. In all 18 parameters of the distal femur were measured including the anteroposterior (AP) dimension of femoral condyles, the mediolateral (ML) width of the distal femur at four levels, and the AP dimension and ML width of the trochlea. The aspect ratios between the AP and ML dimensions were calculated to determine whether there is a shape difference between genders. Results The female distal femur is significantly smaller in all measured parameters. The mean AP/ML aspect ratio of the female distal femur is significantly larger ( p
