Adductor Canal and Pes Anserinus

00:01 Now let's have a look at the adductor canal.

00:03 We've spoken about the adductor canal a few times, and this is adductor canal is an important continuation of the apex of the femoral triangle.

00:12 It importantly has an anterior wall which is known as sartorius.

00:16 It has a lateral wall where vastus medialis has a contribution.

00:20 And here we can see the femoral artery and the femoral vein passing down from the apex of the femoral triangle into the adductor canal.

00:29 They're running superficial to adductor longus.

00:32 And here, we can see them running through adductor Magnus.

00:34 through adductor Magnus.

00:35 That's hiatus created and this adductor longus and adductor Magnus from the postural medial wall of this canal.

00:44 The contents of the adductor canal, we can see here, as the femoral artery and vein.

00:49 And once again, we can now appreciate the abductor hiatus formed from the hamstring and the abductor portion of that muscle.

00:56 This allows these blood vessels to pass from the anterior aspect of the thigh into the posterior aspect, and then the popliteal fossa, which we can see previously.

01:06 This is an important transition point because although these arteries and veins stayed as the same blood vessels, they change their name.

01:14 So as they leave the femoral aspects of the thigh where the femur is located, the femoral artery and vein, they enter the popliteal fossa, they assume a different name as the popliteal artery and vein.

01:27 Now let's turn to the Pes Anserinus.

01:29 The Pes Anserinus is an important collection of tendons that are approaching the medial aspect of the tibia.

01:38 So here we can see, it's formed by the tendons of sartorius, the tendons of gracilis and the tendons of semi tendinosis.

01:47 And these three tendons, they run on the medial aspects of the tibia, and the known as the Pes Anserinus.

01:54 These are really important.

01:56 On the lateral aspect, you had the iliotibial tract, the direct continuation of the tensor fascia lata muscle.

02:04 That helps to stabilize the knee laterally.

02:07 The combination of these three tendons sartorius, gracilis, semi tendinosis helps to stabilize the knee medially.

02:14 Together they're known as the pes anserinus.
