These are complex articular fractures of the proximal tibia, articular simple and metaphyseal simple. These are almost always high velocity injuries with significant damage to the soft tissue envelope. The state of the soft tissue envelope will dictate the timing and the type of the definitive intervention. These fractures are fracture dislocations of the knee and the joint is always unstable.
Intraarticular fractures should not be immobilized except as a temporizing measure prior to definite surgical treatment.
