Fractures of the distal femur may be extraarticular or have an intraarticular component. Mismanagement of any of these fractures can result in abnormalities of alignment of the load-bearing axis of the lower limb and/or rotational deformities. These can have profound biomechanical consequences.
Additionally, the intraarticular fractures can result in joint irregularities leading to degenerative joint disease.
Treatment is based on sound bone healing with full restoration of the biomechanical axes and of the joint surfaces.
Accurate diagnosis and categorization of the injury anatomy leads to a full understanding of the repertoire of treatment methods, wise surgical decision making and improved outcomes.
