Patient-reported outcome measures (PROM; International Knee Documentation Committee subjective knee form [IKDC]), Visual Analog Scale [VAS] for pain, Tegner Activity Scale [TAS], and satisfaction with the postoperative results (1\u201310-scale, 10 = highest satisfaction) and weight-bearing whole-leg anteroposterior radiographs were conducted pre- and postoperatively. The change in PROM and femorotibial angle (FTA) were tested for statistical significance.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>In total, 12 patients (14 knees) were included (66.7% female; mean age: 33.8\u2009\u00b1\u2009SD 6.6\u00a0years). In ten cases, lateral opening-wedge distal femoral osteotomies (DFO) were performed, of which three cases included a concomitant femoral derotation. Three medial closing-wedge DFO and one medial closing-wedge high tibial osteotomy were performed. At follow-up (55.3\u2009\u00b1\u200929.3\u00a0months), a significant improvement in knee function (IKDC: 56.4\u2009\u00b1\u200914.4 to 69.1\u2009\u00b1\u200911.2, <jats:italic>p<\/jats:italic>\u2009=\u20090.015) and reduction in pain (VAS for pain: 3.5 [interquartile range 2.3\u20135.8] to 0.5 [0\u20132.0], <jats:italic>p<\/jats:italic>\u2009=\u20090.018) were observed.

Additionally, a significant correction of valgus malalignment was observed (5.0\u00b0\u2009\u00b1\u20092.9\u00b0\u00a0valgus to 0.7\u00b0\u2009\u00b1\u20093.2\u00b0\u00a0varus, <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001).
