- articulation: modified hinge joint between the medial and lateral condyles of the femur and the tibial condyles
- joint: knee
- ligaments: transverse ligament of the knee, medial and lateral menisci, anterior and posterior cruciate, arcuate and oblique popliteal, coronary, and posterior meniscofemoral, popliteal, and medial and lateral collateral ligaments 1
- movements: knee flexion, extension, and internal and external rotation (during knee flexion)
- blood supply: branches of femoral, popliteal, and circumflex fibular arteries, and posterior recurrent branches of posterior tibial artery 1
- innervation: branches of femoral, obturator, common fibular, tibial, and saphenous nerves 1
The articulation occurs between the medial and lateral femoral condyles and the tibial condyles.
There are a number of different muscles that permit flexion, extension, and internal and external rotation of the knee joint. See: movements of the knee.
Twelve bursae exist near the tibiofemoral joint. These are located anterior, lateral, medial, and posterior to the tibiofemoral joint, and may communicate or non-communicate with the joint. See: knee bursae.
Branches of the femoral, popliteal, and circumflex fibular arteries, and posterior recurrent branches of posterior tibial artery form a peri-articular genicular anastomosis, which in turn provides blood supply to the tibiofemoral joint1.
