ABSTRACT
A review is presented on the anthropometric parameters of the normal radiological knee and leg bones that can be used to ascertain sex and identify race. Sexual dimorphism has been shown to exist between species but the degree of dimorphism may vary and remain uncertain except through certain anthropometric parameters. The Tibio femoral angle, femoral condyle angle, Tibia condyle angle, Quadriceps angle, distal femur anthropometry as well as knee height ratios have been researched and shown not only to be sexually dimorphic but also identify race. These parameters have shown significant differences between males and females in Africans (Nigerians and Malawians) as well as Caucasians and comparison between African values and Caucasians have shown significant differences defining race. Knee height ratios although not sexually dimorphic in Nigerians as with Caucasians; show racial differences between Nigerians and Caucasians.
This knowledge could help in implants design and prosthesis for
particular sex and race and also help in forensics to determine gender and race in skeletal remains and specimen.
