The lateral superior genicular artery is a branch of the
popliteal artery
The popliteal artery is a deeply placed continuation of the femoral artery opening in the distal portion of the adductor magnus muscle. It courses through the popliteal fossa and ends at the lower border of the popliteus muscle, where it branches ...

knee
In humans and other primates, the knee joins the thigh with the leg and consists of two joints: one between the femur and tibia (tibiofemoral joint), and one between the femur and patella (patellofemoral joint). It is the largest joint in the hu ...

Course
It passes above the lateral condyle of the femur, beneath the tendon of the
Biceps femoris
The biceps femoris () is a muscle of the thigh located to the posterior, or back. As its name implies, it has two parts, one of which (the long head) forms part of the hamstrings muscle group.
Structure
It has two heads of origin:
*the ''long h ...

Branching
It divides into a superficial and a deep branch; the superficial branch supplies the
vastus lateralis
The vastus lateralis (), also called the vastus externus, is the largest and most powerful part of the quadriceps femoris, a muscle in the thigh. Together with other muscles of the quadriceps group, it serves to extend the knee joint, moving the l ...

lateral femoral circumflex
The lateral circumflex femoral artery, also known as the lateral femoral circumflex artery, or the external circumflex artery, is an artery in the upper thigh. It is usually a branch of the profunda femoris artery, and produces three branches. It ...

The descending genicular artery (highest genicular artery) arises from the femoral artery just before it passes through the adductor hiatus.
It immediately divides into two branches:
* a saphenous branch, which classically joins with the medial ...
