Distal femoral morphology: The difference between genders
Abstract We measured 11 linear morphometric parameters of 100 human femurs of which 52 were male and 48 female, to ascertain the difference between male and female femora. The epicondylar width (EBW) mean was 82.65±3.96 mm in male and 72.47±3.49 mm in female samples (p<0.001). Intercondylar notch width (ICW) mean in males was 19.32±4.10 mm, in the females 18.04±3.40 mm (p<0.01). Intercondylar notch height (ICH) mean in males was 29.05±4.57 mm and in the females 26.85±4.10 mm (p<0.5). Maximal Medial Condylar Width (MCWmax) was 35.86±2.89 mm in males and 31.50±2.86 mm in females (p<0.001). Medial condylar width (MCW) was 26.73±2.77 mm in males and 23.81±3.01 mm in females (p<0.001). Maximal Lateral Condylar (LCWmax) width was 36, 05±2.68 mm in males and 31.70±2.03 mm in females (p<0.001). Lateral Condylar Width (LCW) was 28.11±2.71mm in males and 24.45±2.61 mm in females (p<0.001). Medial Condylar Height (MCH) in males was 38.40±3.91 mm and in females 33.02±4.01 mm (p<0.001). Lateral Condylar Height (LCH) was 39.25±3.54 mm in males and 32.83±3.54 mm in females (p<0.001). Medial Condylar Depth (MCD) was 61.88±4.04 mm in males and 54.45±3.59 mm in females (p<0.001). Lateral Condylar Depth (LCD) was 64.67±4.48 mm in males and 56.68±3.62 mm in females (p<0.001). The obtained information can be used for gender specific total knee protheses, understanding ACL rupture epidemiology and identifying the gender of skeletal remains.
