33B1.1/.2 Partial articular fracture, lateral condyle, sagittal simple
General considerations
These simple articular fractures may run through the notch or through the condylar load-bearing surface.
Partial articular fractures of the lateral condyle in the sagittal plane result from valgus stress, of medium to low energy, often combined with a rotational component. These fractures are not common. They may be associated with ligamentous injuries to the knee. They are challenging to fix in osteoporotic bone.

33B1.2 Simple, through the condylar load-bearing surface
This arthroscopic view shows a typical articular fracture through the load bearing surface. The lateral meniscus is seen at the bottom. Note the severe cartilage damage, which will finally define the outcome.
