A COMPARATIVE STUDY OF HIGH TIBIAL OSTEOTOMY USING TAGUCHI METHOD

High Tibial Osteotomy (hereinafter HTO) is a treatment method of goanarthrosis of the human knee. There are several HTO types, but the most frequent ones are the monoplanar Opening Wedge High Tibial Osteotomy (hereinafter OWHTO), the biplanar Opening Wedge High Tibial Osteotomy (hereinafter BOWHTO) and the Closing Wedge High Tibial Osteotomy (hereinafter CWHTO). This paper aims to carry out a comparative study of these procedures using engineering research methods (CAD, FEM, DOE). Specifically, a static analysis of the stress state will be performed on the intraoperative behaviour of the tibia during the realization of the corrective angulation through the prism of three variables, i.e.: HTO type, angular value and distance to the lateral cortical side of the tibia. The results obtained are eloquent and clearly presented and may constitute important elements for orthopaedic physicians
