Distal Femoral Dimensions in Turkish Population and Their Implications in Knee Prosthesis.

Background: Total knee prosthesis is a frequently used material in surgery. Distal femur measurements must be taken into account to use the correct prosthesis. The aim of this study is to guide the development of a knee prosthesis suitable for distal femur dimensions in the Turkish population. Thus, it was planned to guide the Turkish population in choosing the most suitable knee prostheses imported from abroad.

Methods:  Using 138 dry bones in the study, at first, the sides of the femurs were determined and eight parameters from femur distal and proximal parts were measured by a measuring tape and a digital caliper. Five parameters were measured at the distal part to evaluate whether these parameters differ according to the femur side.

Results: According to the results, distal femur measurements do not differ by side. Distal femur measurements in the Turkish population are wider than distal measurements of the Far East and Asian populations. These measurements are more similar to the measurements of the North American population. Also, the femur can be safely used in cases where there is no possibility of making a gender determination with the pelvis or the skull.

Conclusions: The femur's distinct morphological differences between genders offer invaluable insights for anthropometric gender determination. Our study underscores the importance of considering morphological and metric measurements and sets the stage for further research in this domain.
