Morphometry of the bony components of the knee joint is important in clinical, forensic and medico-legal applications. The aim of this study was to evaluate the mean values of the femoral and tibia condyle angles of the normal knee joint of Nigerians. A total of 500 standard Anteroposterior radiographs of the knee of Nigerians collected from the radiology departments of various teaching hospitals across Nigeria were used. From the obtained radiographs, the femoral condyle and tibia condyle angles were measured using meter rule and goniometer by standard protocols described by literature. Analysis was done using SPSS 20.0 version; hence mean and standard deviation was obtained. Z-test was used to compare mean values at 0.05 significant levels. The index of sexual dimorphism was also applied to ascertain level of sexual difference. The results showed sexual dimorphism in the femoral and tibia condyle angles measured (p<0.05). Racial dissimilarities were seen in mean values when compared with other races. Knowledge of these values is important in evaluation of sex, racial differences and in clinical applications. Thus, it is recommended that anatomist, forensic anthropologist, radiologists, orthopedic surgeons and orthopedic manufacturing companies adopts these findings as a reference guide for the Nigerian population.
