Type I: Type 1 is the same as the true injury Blake and McBryde described with extra-articular fractures of both bones [3, 4].Type II is subdivided into 3 groups, as follows: Type II A: Type 2a involves femoral shaft and tibial plateau fractures. Type II B: Type 2b includes fractures of the distal femur and the shaft of the tibia. Type II C: Type 2c indicates fractures of the distal femur and tibial plateau.
