What is the "Hoffa Sign" used for?

  • Hoffa Sign indicates a chronic Achilles tendon tear.

How to perform the "Hoffa Sign"?

  • The patient is prone with the feet projecting over the edge of the examining table.
  • The examiner passively dorsi flexes both feet.

What is the positive result?

  • In a chronic Achilles tendon tear, tension in the Achilles tendon will be reduced and the affected foot can be dorsi flexed farther than the contralateral foot. 
  • The patient is then requested to stand on tiptoe on each leg. 
  • This will be impossible with an Achilles tendon tear in the injured leg.
