The Articular Capsule of the Knee


The Patellar Ligament or Ligamentum Patellae (pp. 478-9)


Patellar Reflex

With the leg flexed, the patellar ligament is struck to elicit a knee jerk. This patellar reflex or knee reflex results in the extension of the leg. This reflex is blocked by damage to the femoral nerve, which supplies the quadriceps muscle. Similarly, damage to the reflex centres in the spinal cord (L2, L3, and L4) will affect the patellar reflex.
