was changed:
The patellofemoral joint is a synovial joint between the condyles of the femur and the articular surface of the patella. It is part of the knee joint.
Gross anatomy
Components
- medial, lateral and odd facet on the posterior surface of the patella articulate with the medial and lateral condyles of the femur
- the lateral facet is the largest and steepest facet
- articular surface: hyaline cartilage
- capsule: fibrous capsule and synovial membrane is continuous with the knee joint
Movement
- sliding articulation with knee flexion and extension
Ligaments
- patellar tendon
- medial and lateral patellar retinaculum
- medial patellofemoral ligament
Movement
sliding articulation with knee flexion and extension
Relations
- anterior: patella
- posterior: femoral condyles, intercondylar groove
- inferior: patellar tendon, infrapatellar bursa, infrapatellar fat pat, knee joint
- superior: suprapatellar bursa, common tendon of quadriceps
Blood supply
- superior medial and lateral geniculate arteries (popliteal artery)
- inferior medial and lateral geniculate arteries (popliteal artery)
- descending geniculate branches (femoral and lateral circumflex femoral arteries)
Innervation
- femoral, tibial, common fibular and obturator nerves
Variant anatomy
- variant patellar shape and position
- bipartite/multipartite patella
- absent patella
- dorsal defect of patella
