Case contributed by Varun Babu


Bilateral knee pain

Patient Data

Age: 50
Gender: Male

Coronal proton density weighted fat suppressed and T1 weighted spin echo images reveal an unfused accessory ossification center along the superolateral aspect of the patella. This should not be confused with a patellar fracture. 

Case Discussion

Usually bipartite patella are incidental findings. However they may present with anterior knee pain. Typically they are incidentally dropped upon when patient is evaluated for some other knee signs and symptoms. Knowledge of this variant is important to not overcall patellar fractures.
