Patellofemoral joint

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.

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
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
  • 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)
