Partial articular, medial sagittal fragmentary fracture (AO/OTA 34B2.2)

Partial articular, fragmentary, lateral, fractures of the lateral patella are classified by AO/OTA as a 34B2.2 fracture.

They may be due to direct impact to the front of the knee (eg, dashboard injury). The surgeon must not confuse a well-corticated superolateral bipartite patella with an acute fracture.
