Line 58: Line 58:     
Contraction of the quadriceps while in rest enables the patella to be hooked over the trochlea of the femur due to the binding loop formed by the patella, middle and medial patellar ligaments.  The '''femeropatellar joint''' capsule sometimes communicates with the '''lateral femerotibial''' cavity and usually with the '''medial'''. No communication exists between the femorotibial joints.
