Figure 1 The ultrasonographic views: the apex of the femoral triangle (A) and the distal end of the adductor canal (B). The apex of the femoral triangle (A) was found at the level where the medial border of the sartorius muscle (yellow arrow) intersects the medial border of the adductor longus muscle (green arrow). Local anesthetic was injected laterally to the femoral artery (yellow star) where the saphenous nerve is located. The distal end of the adductor canal (B) was found at the level where the femoral artery and vein dive deeper from the sartorius muscle and become the popliteal vessels. The needle (pink arrowhead) was placed and the local anesthetic was injected above the artery. SM – sartorius muscle; AL – adductor longus muscle; VM – vastus medialis muscle; AM – adductor magnus muscle; Gr – gracilis muscle; SmM – semimembranosus muscle; A – femoral artery; V – femoral vein; LA – spread of local anesthetic after injection.
