The management of these fractures can be difficult; a stable repair of the tibial tubercle fragment is essential if the extensor mechanism is to be reconstituted. There are few reported techniques described to manage tibial tubercle fractures in conjunction with complex proximal tibial injuries. Traditionally, tibial tubercle fractures have been repaired by lagging the tubercle fragment to the posterior cortex of the tibia using 1 or more screws. However, the cortex of the posterior tibia does not always offer good purchase for screw fixation, particularly in osteopenic bone. Additionally, in complex proximal tibial fractures, comminution often extends posteriorly, further complicating stable lag screw fixation. Placement of an anteroposterior lag screw can also be complicated by screw traffic if there are a lar
