33B1.1/.2   Partial articular fracture, lateral condyle, sagittal simple

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.

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.
