    Transcript

    00:01 Let’s just have a look at the pes anserinus. I’ve mentioned this a few times before. This really is a collection of three tendons that are going to the superomedial aspect of the tibia.

    00:14 So here, we can see we have three tendons. We’ve got the femur here. This is a slightly kind of lateral view here of the knee joint. And we can see the femurs being exposed.

    00:29 We can see we’ve got the patellar here, and we’ve got the quadriceps tendon, we’ve got the patellar tendon. And we can see just medial to the patellar tendon in the tibial tuberosity, we’ve got three tendons - the tendon for sartorius, the tendon for gracilis, and the tendon for semitendinosus. Collectively, this is known as the pes anserinus.

    00:52 We can see these muscles here on the medial view of the knee. We have this muscle here, sartorius.

    01:01 We then have this muscle here, gracilis. And then we have this muscle here, semitendinosus.

    01:08 And these are all passing just medial to the patellar tendons insertion onto the tibial tuberosity. So it’s a common attachment site for three muscles, sartorius, gracilis, semitendinosus, and it helps to stabilize the knee joint, just like the iliotibial tract stabilize the knee joint on the lateral aspect. Now, I want to talk about the femoral triangle.
