Open Reduction and Internal Fixation of the Tibial Plateau Through the Anterolateral Approach.

Abstract

Fractures of the tibial plateau are challenging injuries to treat. The lateral tibial plateau is fractured more commonly than the medial plateau and the workhorse approach for these fractures is the anterolateral approach. This approach allows visualization of the lateral joint, metaphysis, and can be extensile if there is shaft extension. We present our technique for performing the anterolateral approach while treating a Schatzker III tibial plateau fracture. Special attention is given to performing a submeniscal arthrotomy to view the joint surface and judge the reduction. A femoral distractor is placed to assist with elevation the joint surface and visualization of the lateral plateau. A cortical window is created using a triple reamer from the sliding hip screw set. The reduction is performed and supported with cancellous bone chips. Finally, a lateral locking plate with rafting screws is placed. Knowledge of this approach and the strategies needed to address lateral and some bicondlar tibial plateau fractures are crucial to good patient outcomes.
