Hoffa Sign
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.
