1. A method of performing a proximal tibial osteotomy comprisingproducing a curvilinear cut adjacent the proximal metaphysis of the tibia, the lower part of which cut is concave as viewed from such metaphysis, such cut being made generally perpendicular to the sagittal plane, to free a caudal, tibial portion within the metaphyseal region of the tibia for movement relative to the remaining portion of the tibia that includes the diaphysis of the tibia and the tibial crest,rotating the two thus-cut-separated tibial portions to produce a new angular relationship therebetween in such plane without effecting translation of the thus-cut-separated tibial portions relative to one another, andfixing the two thus-rotated portions to anchor them in such new angular relationship.
