[1][2] This point of origin is distal to the superior genicular arteries, and between, equidistantly, the medial condyle of femur and the lateral condyle of femur.
[2] As a normal variation, the MGA may emerge from the popliteal artery at a common point of origin shared with the superior lateral genicular artery, or both vessels may arise at separate, distinct points.
It pierces the oblique popliteal ligament and the joint capsule of the knee.
[2] The middle genicular artery may be damaged during knee arthroscopy, particularly using a posterior approach through the popliteal fossa.
[1] It may also be damaged in traumatic injuries to the knee, often caused by sports.
