Introduction: Femur is an important component of the lower kinetic series and functions as a weightbearing
bone. The distal end of femur’s morphometry is vital in the designing the implants for total joint
arthroplasty. The design of prosthesis is based on morphometry of the distal end of the femur. To ensure
the early mobility as well as fewer complications after total knee arthroplasty, the designing of prosthesis
based on morphometric values of distal end of femur plays a key role.
Objectives: To study the morphometric data of the distal end of femur. To compare the morphometric data
between right and left femur.
Materials and Methods: One hundred and eighty femurs of unidentified sex were measured for the width
of Bicondylar, the maximum medial and lateral condyle anteroposterior length, the total transverse distance
of the medial and lateral condyle, and the width of intercondylar notch.
Results: The average bicondylar width of entire femur sample was 71.32 5.91 mm, mean anteroposterior
diameter of medial and lateral condyle were 56.12 4.51 mm and 56.85 4.31 mm respectively. The
medial and lateral condyle mean transverse distance of was 28.33 3.49 mm and 30.7 3 3.21 mm
respectively. It was found that the mean intercondylar notch width was 21.62 2.92 mm. In this study,
there were no statistically significant parameters between right and left femur.
Conclusion: The data obtained from this study will help the biomedical engineers to design the knee
replacement prosthesis of suitable size for Indian patients undergoing knee replacement operations.
