Knee Anatomy Flashcards
1
Q
Joints of the knee
A
Tibiofemoral joint - medial and lateral condyles of the femur articulate with the tibia
Patellofemoral joint - anterior and distal part of the femur articulate with the patella
Superior tibiofibular joint – Tibia and fibular. Not directly involved at the knee joint.
2
Q
Ligaments at Tibiofemoral joint
A
- MCL/Tibial collateral (Medial Collateral Ligament) - Medial femoral epicondyle to medial tibial condyle, Limits extension and abduction of leg; attached to medial meniscus.
- LCL/Fibular collateral (Lateral Collateral Ligament) – Lateral femoral epicondyle to fibular head, Limits extension and adduction of leg; overlies popliteus tendon
- ACL (Anterior Collateral Ligament) – Anterior intercondylar tibia to lateral femoral condyle, Prevents posterior slipping of femur on tibia; torn in hyperextension
- PCL (Posterior Collateral Ligament) – Posterior intercondylar tibia to medial femoral condyle, Prevents anterior slipping of femur on tibia; shorter and stronger than anterior cruciate
- Transverse Ligament - Anterior aspect of menisci, Binds and stabilises menisci

Ligaments at the Patellofemoral joint
A
Patellar ligament - Patella to tibial tuberosity
