Anterior patella apophysis

Case contributed by Dr Jeremy Jones


Knee pain following direct trauma after fall.

Patient Data

Age: 10 years old

On the lateral film, there is a small focal ossific density projected anterior to the patella. This represents non-union of the anterior patella apophysis (normal variant) rather than an avulsion injury.

Case Discussion

Non-union of an anterior patella apophysis is a normal variant and does not represent an avulsion injury. Differential diagnosis: sleve fracture.
