Research has shown that variations in femoral intercondylar notch morphometry may be a predisposing factor for noncontact anterior cruciate ligament injury.
There are anatomic differences in the anterior cruciate ligament and femoral notch between men and women.
Descriptive anatomic study.
Using magnetic resonance imaging, we performed a three-dimensional analysis of the femoral intercondylar notch morphometry to look for differences in femoral notch and anterior cruciate ligament volumes between men and women. Axial plane magnetic resonance imaging scans were performed on 96 knees in 48 asymptomatic subjects. Digital measurements were taken of femoral notch area, anterior cruciate ligament area, notch width, and bicondylar width, within defined parameters of the femoral notch. The notch and anterior cruciate ligament volumes were then calculated. Analysis of variance was performed using sex, height, and weight as covariates.
The volume of the femoral notch was found to be statistically smaller in women compared with men; this difference was primarily related to height. A similar relationship was found for anterior cruciate ligament volume. A statistically significant correlation was found between femoral notch volume and anterior cruciate ligament volume; patients with smaller notches also had smaller anterior cruciate ligaments.
Our results suggest that there is a difference in femoral notch and anterior cruciate ligament volume between men and women, which, in turn, is related to differences in height and weight.
研究表明，股骨髁间窝形态测量的差异可能是非接触性前交叉韧带损伤的一个诱发因素。
男性和女性的前交叉韧带和股骨髁间窝存在解剖学差异。
描述性解剖学研究。
我们使用磁共振成像对股骨髁间窝形态测量进行三维分析，以寻找男性和女性在股骨髁间窝和前交叉韧带体积上的差异。对48名无症状受试者的96个膝关节进行了轴向平面磁共振成像扫描。在股骨髁间窝的定义参数内，对股骨髁间窝面积、前交叉韧带面积、髁间窝宽度和双髁宽度进行数字测量。然后计算髁间窝和前交叉韧带的体积。以性别、身高和体重作为协变量进行方差分析。
发现女性的股骨髁间窝体积在统计学上比男性小；这种差异主要与身高有关。在前交叉韧带体积方面也发现了类似的关系。在股骨髁间窝体积和前交叉韧带体积之间发现了统计学上的显著相关性；髁间窝较小的患者前交叉韧带也较小。
我们的结果表明，男性和女性在股骨髁间窝和前交叉韧带体积上存在差异，而这又与身高和体重的差异有关。
