Fouchet’s Test or Fouchet’s Sign is a clinical examination of the knee that, if positive, may suggest the diagnosis of chondromalacia patella and/or other knee related disorders.


  1. Patient supine with legs straight
  2. Examiner applies downward pressure over the patella with palmar surface of the hand in a circular motion.
  3. Examiner observes the patient for signs of pain or discomfort.
  4. If no sign of discomfort or pain is noted, the examiner then proceeds to move the patella from side to side


Positive Fouchet’s Test

Any sign of pain and audible or palpable crepitus (grating, crackling, or popping sounds) may indicate any of the following:

  • Patellar tracking disorder
  • Peri-patellar syndrome
  • Patellofemoral dysfunction
  • Chondromalacia patella

  1. Vastus medialis oblique deficiency
