Through anatomical dissection of fifty freshly amputated adult lower extremities, the origin, length, diameter and extent of perfusion of the superior genicular artery and its relation with the anterior tibial recurrent artery were investigated. Results revealed that the medial superior genicular artery originated primarily from the femoral artery (95.5%). It descends between the sartorius and majormedial muscles and then separates into branches that nourish the upper one-third of the lower leg and the medial skin of the knee, and then, by anastomosis, joins the anterior tibia recurrent artery on the level of the medial malleolus of the tibia. The formation rate of the anastomotic arch is 100% with the average outer diameter of 1.3 +/- 0.39 mm (x +/- s). Based on these observations, we conclude that the medial area of the knee is the best donor site of an island flap, which can be used to repair the medial superior one-third of the lower leg and the region around the knee.
通过对50条新鲜截肢的成人下肢进行解剖，研究了膝上动脉的起源、长度、直径、灌注范围及其与胫前返动脉的关系。结果显示，膝上内侧动脉主要起源于股动脉（95.5%）。它在缝匠肌和大内侧肌之间下行，然后分支营养小腿上三分之一和膝关节内侧皮肤，随后通过吻合在胫骨内踝水平与胫前返动脉相连。吻合弓的形成率为100%，平均外径为1.3±0.39mm（x±s）。基于这些观察结果，我们得出结论，膝关节内侧区域是岛状皮瓣的最佳供区，可用于修复小腿上内侧三分之一和膝关节周围区域。
