One hundred ten patients each in the MM PRT group and the MM NRT group, who were matched through propensity score matching (adjusting for confounding factors such as age, sex, body mass index, anatomic axis, cartilage state of the medial compartment, and follow\u2010up period), were included in the study. The MA angle on weightbearing whole\u2010leg radiographs and the medial JSW on weightbearing 45\u00b0 flexion posteroanterior radiographs were measured to evaluate the radiographic outcomes. The serial changes were compared between radiographs taken before surgery, at postoperative 3 to 5\u00a0years, and at postoperative 5\u00a0years to the last follow\u2010up. The linear mixed model was used to compare the changes in radiographic outcomes during the follow\u2010up period between groups.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The 2 groups were balanced with standardized mean differences of &lt;0.2 after propensity score matching. Both the MM PRT and NRT groups showed increased varus alignment after surgery. However, there was no significant difference in the change in the MA angle during the follow\u2010up period between groups (\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0= .182).
