The invention provides an osteotomy device, a kit, and methods for realigning varus angulated knees. The device involves a substantially wedge shaped body (100) having two intersecting principal surfaces (112, 114) angularly offset. These principal surfaces extend in a direction of a drive axis about a principal plane from an insertion end to a drive surface at a drive end (11). At least one of the principal surfaces is adapted to engage mechanically a surface adjacent thereto. The drive surface is also adapted to receive a force in the direction of the drive axis toward the insertion end. The kit of the present invention includes substantially such an osteotomy device having a cannular opening along its drive axis and an osteotomy pin. A method of the invention involves making a transverse incision partially into the tibia; realigning tibial portions above, and below the incision with respect to each other to create a predetermined angle (A) between opposing faces of the incision, thereby creating a wedge shaped opening (142) providing substantially wedge shaped body having two angularly offset intersecting principal surfaces, wherein at least one of the surfaces is adapted to engage mechanically a surface adjacent thereto; and driving the body into the opening.
