Definition
The popliteal artery is the continuation of the femoral artery behind your knee. It supplies blood to the knee joint and lower leg. Think of it as the critical link delivering nutrients to your lower leg and foot. It's located in the popliteal fossa, the hollow behind your knee. It branches into other arteries that supply the calf and foot. It is vulnerable to injury due to its location. It's a key artery for leg movement.
