- Discussion:
    - descending genicular artery  arises superomedially from from superficial femoral artery  just proximal to adductor hiatus, and then immediately, it
             divides into the saphenous and articular branches;
    - saphenous branch anastomosises w/ medial inferior genicular artery;
    - articular branch: descends in the substance of the vastus medialis;
            - it supplies vastus, & then pass over patellar surface to anastomose with other genicular arteries; (see Genicular art. system)

Safe zone for the descending genicular artery in the midvastus approach to the knee
