An osteological study of distal end of femur in adult south Indian population

Abstract

Background: Need for the study: Anthropometric studies across different population groups have exhibited significant difference between races. Hence the usage of implant for total knee arthroplasty has to be gender specific and race specific. This study was undertaken to analyse the morphometry of distal end of femur in South Indian population. Aims and objectives: To analyse the morphometry of distal end of femur and to study the anteroposterior dimensions of condyles of femur, bicondylar width, intercondylar notch width. Materials and Methods: The study was conducted on 150 femur (80 right and 70 left) obtained from Department of Anatomy of a private medical college. Measurements of anteroposterior dimensions of condyles of femur, bicondylar width, intercondylar notch width were taken using a sliding calipers. Conclusions: In the present study, mean Bicondylar width noted in the present study is 72.63 ±4.13 mm on the right side and 71.25±3.14mm on the left side The mean intercondylar width observed is 21.27±4.18mm on the right side and 20.35±2.14mm on the left side. There was no statistically significant differences observed in the values of anteroposterior length of medial and lateral condyles, bicondylar width, intercondylar width between right and left sides. The results of the study has application in the field of biomedical engineering to design knee implants specific for South Indian population.
