最近，已经开发出针对性别的全膝关节置换术，以适应男性和女性之间的解剖学差异。我们检查了一组年龄和身高相匹配的男性和女性股骨远端，以确定两性之间的纵横比（中外侧距离与前后距离）和前凸缘高度是否存在差异。 Hamann-Todd Collection 提供了 1207 具骨骼成熟的尸体股骨。测量所有标本的股骨长度、前后高度、外侧和内侧凸缘的高度以及内侧宽度。评估股骨的机械轴、切割关节宽度和纵横比。对性别对长宽比以及外侧和内侧凸缘的影响进行了统计分析，控制了年龄、身高和种族。男性股骨的平均长宽比为 1.21 (SD 0.07)，女性股骨的平均长宽比为 1.16 (SD 0.06) (p < 0.001)。雄性和雌性标本的外侧凸缘平均尺寸（分别为 6.57 毫米（SD 2.57）和 7.02 毫米（SD 2.36）；p = 0.099）或内侧凸缘（分别为 3.03 毫米（SD 2.47）和 3.56 毫米（SD 2.32）；p = 0.67）没有显着差异。膝关节假体设计的未来工作应考虑股骨远端解剖结构的整体变异性。
Recently, gender-specific designs of total knee replacement have been developed to accommodate anatomical differences between males and females. We examined a group of male and female distal femora matched for age and height, to determine if there was a difference in the aspect ratio (mediolateral distance versus anteroposterior distance) and the height of the anterior flange between the genders. The Hamann-Todd Collection provided 1207 skeletally mature cadaver femora. The femoral length, the anteroposterior height, height of the lateral and medial flanges and the mediolateral width were measured in all the specimens. The mechanical axis of the femur, the cut articular width and the aspect ratio were assessed. Statistical analysis of the effect of gender upon the aspect ratio and the lateral and medial flanges was undertaken, controlling for age, height and race.The mean aspect ratio of male femora was 1.21 (SD 0.07) and of female femora it was 1.16 (SD 0.06) (p < 0.001). There was no significant difference between male and female specimens in the mean size of the lateral flange (6.57 mm (SD 2.57) and 7.02 mm (SD 2.36), respectively; p = 0.099) or of the medial flange (3.03 mm (SD 2.47) and 3.56 mm (SD 2.32), respectively; p = 0.67). Future work in the design of knee prostheses should take into account the overall variability of the anatomy of the distal femur.
