The intricate geometry of the cruciate ligament and the lack of adequate description of the methods used to obtain its cross-sectional area have complicated the normalization of the load-elongation data in terms of stress and strain respectively. An experimental study was undertaken to quantify the dependence on the applied pressure of cross-sectional area in canine ligaments. Twenty-two canine preparations were compressed with a non-rotating spindle blade micrometer (Mitutoyo, 122), whose thimble breakaway tongue develops a constant force of 1.96 N. By the use of matching pairs of plexiglass blocks of various widths, the applied pressure on the ligament could be varied between 0.041 and 0.355 MPa. Data from all the ligaments were reduced to a single curve which illustrates a decrease in the normalized cross-sectional area by 25% for pressures ranging from 0.04 to 0.36 MPa. For all pressures between 0.20 and 0.35 MPa the normalized cross-sectional area remained constant.
十字韧带复杂的几何形状以及获取其横截面积所使用方法的描述不充分，使得负荷-伸长数据分别在应力和应变方面的归一化变得复杂。开展了一项实验研究，以量化犬类韧带横截面积对应用压力的依赖性。使用非旋转主轴叶片千分尺（三丰，122）对22个犬类标本进行压缩，其测微螺杆分离舌产生1.96 N的恒定力。通过使用不同宽度的匹配有机玻璃块对，施加在韧带上的压力可在0.041至0.355 MPa之间变化。所有韧带的数据被简化为一条单一曲线，该曲线表明，对于0.04至0.36 MPa的压力范围，归一化横截面积减少了25%。对于0.20至0.35 MPa之间的所有压力，归一化横截面积保持恒定。
