背景：后交叉韧带重建术的成功率各不相同。本研究的目的是确定定量和定性的地形和骨性标志的股骨足迹的前外侧和后内侧束的后交叉韧带，以提高repair.Methods：20个不成对的膝盖从20人尸体进行了评价。结果：在20例膝关节标本中，18例膝关节后交叉韧带股骨足印近端有一骨性隆起。这个骨性标志，命名为“内侧髁间嵴”，确定了后交叉韧带足印的近端边界。在20个膝关节中的8个中，我们观察到后交叉韧带的前外侧束和后内侧束之间有一个小的骨性突起。在前外侧束和后内侧束之间观察到后交叉韧带股骨足迹的斜率发生明显变化。后交叉韧带足迹的平均面积（和标准差）为209 ± 33.82 mm（2），前外侧束的平均面积为118 ± 23.95 mm（2），后内侧束的平均面积为90 ± 16.13 mm（2）。后交叉韧带的股骨足印区具有独特的表面解剖结构，内侧髁间嵴经常出现，内侧分叉嵴较少出现。临床相关性：这些解剖学发现可能有助于外科医生以更解剖的方式进行后交叉韧带重建。
Background: The success of posterior cruciate ligament reconstruction has varied. The objective of this study was to determine quantitatively and qualitatively the topography and osseous landmarks of the femoral footprints of the anterolateral and posteromedial bundles of the posterior cruciate ligament in order to enhance repair.Methods: Twenty unpaired knees from twenty human cadavers were evaluated. The surface features of the femoral footprints of the anterolateral and posteromedial bundles of the posterior cruciate ligament were studied by means of macroscopic observation and three-dimensional laser photography.Results: We observed, both visually and with three-dimensional laser photography, an osseous prominence located proximal to the femoral footprint of the posterior cruciate ligament in eighteen of the twenty human knees. This osseous landmark, denominated the "medial intercondylar ridge," determined the proximal border of the posterior cruciate ligament footprint. In eight of the twenty knees, we observed a small osseous prominence between the anterolateral and posteromedial bundles of the posterior cruciate ligament. A clear change in the slope of the femoral footprint of the posterior cruciate ligament was seen between the anterolateral and posteromedial bundles. The average area of the posterior cruciate ligament footprint (and standard deviation) was 209 +/- 33.82 mm(2), the average area of the anterolateral bundle was 118 +/- 23.95 mm(2), and the average area of the posteromedial bundle was 90 +/- 16.13 mm(2).Conclusions: The femoral footprint of the posterior cruciate ligament has a unique surface anatomy, with a medial intercondylar ridge being frequently present and a medial bifurcate ridge being less frequently present.Clinical Relevance: These anatomical findings may assist surgeons in performing posterior cruciate ligament reconstruction in a more anatomical fashion.
