The medial superior genicular artery is a branch of the popliteal artery.{{cite web|last=Healthline Editorial Team|title=Medial superior genicular artery|url=http://health.yahoo.net/human-body-maps/medial-superior-genicular-artery|publisher=Yahoo! Health|accessdate=21 October 2012}} It runs deep to the semimembranosus, semitendinosus, and tendon of the adductor magnus,{{Cite book |last=Sinnatamby |first=Chummy |title=Last's Anatomy |publisher= |year=2011 |isbn=978-0-7295-3752-0 |edition=12th |pages=134}} and superior to the medial head of the gastrocnemius.

It divides into two branches, one of which supplies the vastus medialis, anastomosing with the highest genicular and medial inferior genicular arteries; the other ramifies close to the surface of the femur, supplying it and the knee-joint, and anastomosing with the lateral superior genicular artery.

The medial superior genicular artery is frequently of small size, a condition which is associated with an increase in the size of the highest genicular.
