Partial articular fracture, lateral condyle, sagittal fragmentary

Partial articular fractures of the lateral condyle in the sagittal plane are not common. They may be associated with ligamentous injuries to the knee. They are challenging to fix in osteoporotic bone.

These fractures result from valgus stress, of medium to low energy, often combined with a rotational component.

The following 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.
