High Tibial Osteotomy (HTO) is a reliable procedure with proper patient selection and a precise surgical technique for patients who had the medial compartment osteoarthritis of the knee with a varus deformity. HTO has the major advantages in the preservation of bone stock and intra-articular structures. In addition to the coronal alignment of the lower limb following HTO, however, various anatomical elements including the morphology of the proximal tibia, the relative patellar height, the tension of surrounding soft tissues and the whole leg length are changed. These alterations can adversely affect both tibiofemoral and patellofemoral kinematics or the dynamic loading of the knee, which cannot be assessed using conventional radiology. It is necessary, therefore, to evaluate those changes following HTO from many aspects. Identifying and understanding these relationships may lead to further improvement in the clinical success of HTO in the future.
