An osteotomy is a surgical operation whereby a bone is cut to shorten, lengthen, or change its alignment. Corrective tibial osteotomies correct non-physiological axis, thus eliminating knee and ankle joint loads. In preoperative planning of the osteotomy a preoperative drawing should be made and it requires knowledge of biomechanics and physiology of the lower limbs.
Key words: corrective tibial osteotomy, manual planning, computer-aided planning.
