-mechanical axis deviation (in mm) MAD, anatomical and mechanical femoral axes angle (aMFA),mechanical lateral proximal femoral angle (mLPFA), mechanical lateral distal femoral angle(mLDFA), joint line convergence angle (JLCA),mechanical medial proximal tibial angle (mMPTA), Mechanical lateral distal tibial angle (mLDTA), Hip Knee Ankle line (HKA) ,Mid joint line (MJL) orientation.  -to simulate, before real bone cuts are done and try different strategies in relation to the location, the type of osteotomy, the joint obliquity without to redraw in paper board countless drawings in an effort to achieve the optimal correction and mean while taking into account and balancing all influencing preoperative factors.  -pressing + or - button, one degree of correction is added or subtracted respectively and the second plane of osteotomy emerges and printed in screen real offering real time simulation of the wedge osteotomy in an instant to comprehend in real time what parameters are affected and modify favourably the correction angle.  Accurate preoperative planning is mandatory to avoid under correction or overcorrection of axes or placing the joint-line in obliquity that ends to insufficient postoperative alignment.The majority of osteotomies are still planned and performed using conventional techniques drawing over transparent papers, cumbersome measurements etc.  -evaluate in real time the success of intended osteotomy by evaluating the kinematic alignment of the knee (KAO), avoiding residual joint obliquity or malalignment.  -real time dynamically change of mechanical axis lines, modify also the drawings of femur and the tibia and in instant depicting a precise preview of the whole preoperative plan for optimal results.  -the amount of correction preoperatively by calculating the dimension of wedge size , the correction angle and osteotomy gap opening or closing.  -measure the correction angle adjusted due to ligament instability and preoperatively calculate the height of osteotomy gap opening.  - dynamicaly preview and easily predict potential intraoperative errors, that could emerge and choose the optimal degree of correction without disruption kinematic alignment of the limp.  Femoral and tibial osteotomies around the knee are established procedures for the restoration of the physiological load distribution of pressure at the knee joint.  All above mentioned angles and all limp axes are redrawn and updated accordingly for the given new correction angle.  -change the planned mechanical axis to pass at the preferred percentage (Fujisawa point) after evaluation of the residual cartilage thickness left on the involved compartment.  Mal alignment of the hip, knee, and ankle leads to premature cartilage damage and to development of degenerative arthritis of knee joint.  -categorisation of the deformities based to international literature normal references values, help to indicate to user the type of osteotomy.  The drawn schematic gives the impression of settings act as a whole interchangable interacting unit.
