<prompt> Mechanism of injury in lateral condylar fracture of proximal tibia is ?Strain of valgus kneeStrain of varus kneeStrain of valgus knee with axial loadingRotational injury  <response>: A valgus force loads the lateral tibial plateau to failure from direct impact with the lateral femoral condyle. A combination of valgus and axial compression produces lateral side depression,split depression or less commonly lateral split or total lateral condyle fractures. ref : maheswari 9th ed
