- location: knee
- origin: popliteal artery
- supply: cruciate ligaments
The middle genicular artery originates from the anterior aspect of the popliteal artery approximately 3-5 cm above the knee joint line variably having a common origin with one of the other genicular arteries 1-3. It descends along the anterolateral aspect of the popliteal fossa, pierces the posterior knee capsule in the middle of the femoral condyles and is accompanied by two veins 1,2. Within the joint, it travels along the distal part of the posterior cruciate ligament to the anterior cruciate ligament. The length ranges from 3-5 cm with about half of it being extraarticular 1,2.
The middle genicular artery gives small branches to the anterior and posterior cruciate ligaments and their lining tissues 1.
The middle genicular artery participates in the supply of the following structures 1,2:
History and etymology
