From 2004 to 2006, 36 high tibial osteotomies were performed to treat unicompartmental arthritis with a varus deformity. Thirteen patients without instability and with an accurate radiographic evaluation were included. The changes in the deviation of the mechanical axis and femorotibial angle were evaluated retrospectively using whole extremity radiographs immediately after surgery (supine position) and 4\u00a0months after surgery (weight\u2010bearing position). In the nonweight\u2010bearing radiograph obtained immediately after surgery, the mean deviation of the mechanical axis was 22% laterally and the mean femorotibial angle was valgus 8.9\u00b0. The weight\u2010bearing radiograph at 4\u00a0months after surgery showed that the former shifted laterally 34% and the latter shifted valgus 10.6\u00b0. The changes in the mechanical axis and femorotibial angle were significant (<jats:italic>P<\/jats:italic> &lt; 0.001). During open wedge high tibial osteotomy, the surgeon should consider the increase in deviation of the mechanical axis and femorotibial angle after
