Blade-plate assemblies for performing an osteotomy procedure are disclosed. Methods of use and kits are also disclosed. The blade-plate assembly may include a modular blade component configured to be coupled to either a Varus plate component or a Valgus plate component when performing the osteotomy procedure. In some embodiments, the modular blade component includes a support portion and a blade portion that extends outwardly in perpendicular relation to the support portion. The blade portion defines a channel configured to permit passage of a guide wire when performing the osteotomy procedure. The blade-plate assembly disclosed herein simplifies the surgical technique via a chisel-free modular system and creates a biomechanically correct lateralization or medicalization of the femoral shaft depending on the type of osteotomy being performed and type of plate being used.
