The invention relates to a device for reaxing a varus deformed knee. The implant comprises a metal osteotomy case (1) provided with a large bone rehabitation and an angular adjustable correction area. The design of the prosthesis is determined by shapes (L.5, L.8) of lateral medio faces (FS, Fl) and front/rear faces (L.4, L.7). Said body is extended on the rear tibial arms (P.1, P.2) which are slidable with respect to each other in a vertical direction, thereby actuating the opening and closing of the faces (FS, Fl) in such a way that required angular correction is performed. The arm (P.1) is provided with a neck GOC in which a cortico-spongy screw is introduced, wherein said screw is also introduced into the second orifice ORV of the arm (P.2), and, afterwards, into the tibia, thereby locking the angular correction. Hinges (C) are provided with anchor pins (PLT.1, PLT.2) which are fixed to the lower face (FI) and introducible into the orifices (0.1, 0.2) fixed to the top face (FS) for actuating said hinges (C).
