- type A: extraarticular
- type B: partial articular, the fracture is involving one part of the articular surface, yet the rest of the joint is still attached to the metaphysis and diaphysis
- type C: complete articular, the fracture is distributing the joint surface and separated from the diaphysis

Case Discussion
The AO classification divides the distal femoral fractures into three groups, A, B and C with complexity and severity increasing 1.
- type A: extraarticular
- type B: partial articular, the fracture is involving one part of the articular surface, yet the rest of the joint is still attached to the metaphysis and diaphysis
- type C: complete articular, the fracture is distributing the joint surface and separated from the diaphysis
