    Fracture in neck of femur
  • Which condyles of the femur articulate with the tibia?
    Medial and lateral condyles
  • What is the name of the depressed area between the condyles on the femur's posterior surface?

  • Which bones primarily articulate at the knee joint?
    Femur, tibia, fibula, patella
  • What are the functions of the medial and lateral menisci in the knee joint?
