To anatomically evaluate the femoral origin and tibial insertion of the anteromedial and posterolateral bands of the anterior cruciate ligament.
We studied eight cadaver knees as for the following: in the femur, distance from the center of the anteromedial band to the deep cartilage and the ceiling; also in the femur, distance from the center of the posterolateral band to the deep cartilage, to the inferior cartilage and to the superficial cartilage. In the tibia, we measured the distances between the anterior tibial bone edge to the anterior region of the anteromedial band, to the center of the anteromedial band and to the center of the posterolateral band. We also measured the distance between the center of the posterolateral band to the tibial posterolateral bone and the total length of the anteroposterior tibial insertion of the anterior cruciate ligament.
In the femur, the distance from the center of the anteromedial band to the deep cartilage was 6.3 ± 1.4 mm, and 11.2 ± 2 mm to the ceiling. Also in the femur, the distance from the center of the posterolateral band to the deep cartilage was 9 ± 4 mm, to the superficial cartilage 7.6 ± 1.8 mm, and to the inferior cartilage 4.2 ± 0.9 mm. In the tibia, the distance from the anterior tibial bone edge to the anterior region of the anteromedial band was 11.9 ± 2.8 mm, to the center of the anteromedial band 18.8 ± 2.6 mm, and to the center of the posterolateral band 26.5 ± 2.3 mm. The distance from the center of the posterolateral band to the tibial posterior bone edge was 19.6 ± 4 mm and the total length of the anteroposterior tibial insertion of the anterior cruciate ligament was 19.4 ± 1.8 mm.
The center of the tibial insertion of the anteromedial band is approximately 20mm distant from the anterior edge of the tibia, while the center of the posterolateral band is approximately 30 mm. The distance between the center of the origin of the anteromedial band to the deep cartilage is 6mm, and to the posterior lateral 10mm.
对前交叉韧带前内侧束和后外侧束的股骨起点及胫骨止点进行解剖学评估。
我们对8具尸体膝关节进行了如下研究：在股骨上，测量前内侧束中心至深层软骨及骨顶的距离；同样在股骨上，测量后外侧束中心至深层软骨、浅层软骨及下层软骨的距离。在胫骨上，我们测量胫骨前缘至前内侧束前部区域、前内侧束中心及后外侧束中心的距离。我们还测量了后外侧束中心至胫骨后外侧骨的距离以及前交叉韧带胫骨前后向止点的总长度。
在股骨上，前内侧束中心至深层软骨的距离为6.3±1.4毫米，至骨顶为11.2±2毫米。同样在股骨上，后外侧束中心至深层软骨的距离为9±4毫米，至浅层软骨为7.6±1.8毫米，至下层软骨为4.2±0.9毫米。在胫骨上，胫骨前缘至前内侧束前部区域的距离为11.9±2.8毫米，至前内侧束中心为18.8±2.6毫米，至后外侧束中心为26.5±2.3毫米。后外侧束中心至胫骨后缘的距离为19.6±4毫米，前交叉韧带胫骨前后向止点的总长度为19.4±1.8毫米。
前内侧束胫骨止点中心距胫骨前缘约20毫米，而后外侧束中心约为30毫米。前内侧束起点中心至深层软骨的距离为6毫米，至后外侧为10毫米。
