The purpose of the present study was to conduct direct measurements in a large sample of dried femori in order to record certain morphometric parameters of the femoral condyles and determine whether there are gender and side differences. Three hundred sixty (Greek) Caucasian dried femori (180 left and 180 right), from 192 males and 168 females, were measured using a digital caliper. The mean age was 67.52 years. The mean bicondylar width of the femur was 8.86？cm ± 0.42？cm in men and 7.85？cm ± 0.30？cm in women ( ？？ < 0 . 0 1 ). The relative values for the medial condylar depth were 6.11？cm ± 0.34？cm and 5.59？cm ± 0.29？cm ( ？？ < 0 . 0 5 ); for the lateral condylar depth were 6.11？cm ± 0.33？cm and 5.54？cm ± 0.21？cm ( ？？ < 0 . 0 1 ); for the intercondylar width were 2.20？cm ± 0.18？cm and 1.87？cm ± 0.10？cm ( ？？ < 0 . 0 0 1 ); for the intercondylar depth were 2.78？cm ± 0.16？cm and 2.37？cm ± 0.12？cm ( ？？ < 0 . 0 0 1 ). No significant side-to-side difference was observed in any parameter. The femoral condyles differences in anatomy between genders might be useful to the design of total knee prostheses. The contralateral healthy side can be safely used for preoperative templating since there were no significant side differences. 1. Introduction Quantitative anatomy of the distal femur is important for the design of total joint replacement and internal fixation material. Recent studies emphasize on differences between genders and among ethnic groups [1–5]. Preoperative templating for a total knee arthroplasty usually involves the contralateral, healthy side, based on the assumption that there are no side-to-side differences [6]. Furthermore, it has been found that certain osteometric parameters of the femur, such as the femoral intercondylar notch width, differ between genders and are associated with both the volume and the incidence of anterior cruciate ligament (ACL) rupture [7–9]. However, this association has been questioned by other researchers [10, 11]. Most morphometric large sample size studies of the distal femur include measurements on radiographs, computerized tomography or magnetic resonance imaging [1, 9, 11, 12]. A study on 1207 dried femora was published recently, where authors performed measurements using a microscribe digitizer for 3D analysis [13]. In the present study, certain osteometric parameters of the femoral condyles were recorded and the existence of gender and side-to-side difference was examined in 360 Caucasian dried femori. 2. Materials and Methods The sample consisted of 360 paired dried femori (180 left and 180 right) from 192
