Descending genicular artery
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 inferior genicular artery.[1]
- muscular and articular branches.[1]
Structure
Saphenous branch
The saphenous branch pierces the aponeurotic covering of the adductor canal, and accompanies the saphenous nerve to the medial side of the knee. It passes between the sartorius muscle and the gracilis muscle, and, piercing the fascia lata, is distributed to the integument of the upper and medial part of the leg, anastomosing with the medial inferior genicular artery.
Articular branches
The articular branches descend within the vastus medialis muscle, and in front of the tendon of the adductor magnus muscle, to the medial side of the knee, where they join with the medial superior genicular and anterior recurrent tibial artery.
A branch from this vessel crosses above the patellar surface of the femur, forming an anastomotic arch with the lateral superior genicular artery, and supplying branches to the knee-joint.
