目的探讨髌骨上下轴线与胫骨粗隆成角不同度数(@成角)的患者在髌骨纵嵴(TRA图)为基础指导膝关节斜矢扫描显示前叉韧带的关系，总结显示前叉韧带全长最优的扫描角度；要求该扫描角度能达到简捷的扫描全程地显示前叉韧带，节约扫描时间，避免病人不能长时间固定不动及以后多次扫描的情况。方法在不同的腿型如‘O’腿，骨折胫骨平台移位…等病人扫描采取相同人不同的扫描角度，不同情况相同扫描角度，共63例子做对比，根据分类作统计最优化的斜矢位扫描角度。结论根据腿型髌骨下缘与胫骨粗隆成角在(8~18)°、(18~30)°、骨折胫骨外移位者…宜用髌骨纵嵴前后轴线偏内(12~15)°(5~8)°(0~-5)°作倾斜扫描线；图像显示ACL各段比例、走形较真实反映活体组织。

objective and requirements: patellar lower axis and angle of tibial tuberosity into different degrees in patients with patellar longitudinal ridge ( TRA ) based knee oblique sagittal scan display guide front fork ligamentum relationship, summary display front fork ligamentum is best scan angle; the scanning angle can achieve simple scanning the entire process display front fork ligamentum, save the scan time, avoid the patient cannot long time is fixed and after repeatedly scanning case. Methods: in a different leg type such as ' O ' leg fracture of tibial plateau shift ... Patient scan adopted by people of different scan angle, different instances of the same scan angle, a total of 63examples to do comparison, according to the classification of statistical optimization diagonal vector scanning angle. Conclusion: according to the leg patella and the lower edge of tibial tuberosity into a corner (8~ 18°in ), (18- 30)°, fracture of the tibial external displacement ... Should be used before and after patellar longitudinal ridge axis deflection within (12~ 15)°(5~ 8)°, -5° 0 ~dip scanning; image display ACL sections, running more truly reflect the proportion of living tissue.
