股骨远端关节定向线是用于评估股骨角度畸形并为矫正提供指导的解剖标志。特别是，它用于评估解剖学外侧股骨远端角。

在额状面内

股骨远端关节定向线通过髋关节腹背位X线片确定。犬取背卧位，后肢向尾侧伸展，两侧股骨相互平行。若满足以下条件，则认为体位摆放满意：

Peterson等（2020）通过首先识别Blumensaat线（即对应髁间窝顶部的不透射线）来确定股骨远端关节定向线。股骨远端关节定向线是能够沿Blumensaat线绘制的最佳拟合直线。

在矢状面内

股骨远端关节定向线通过整个股骨的内外侧位X线片确定。若内侧髁与外侧髁完全重叠，则认为体位摆放满意。

首先在小转子与滑车沟近端部分之间绘制一条直线。股骨远端关节定向线即为垂直于该第一条线的直线。此线有时被称为股骨远端参考线。
