The mean age of patients was 28.9\u00a0years. Visual analogue scale (VAS<\/jats:styled-content>), Western Ontario and McMaster Universities (WOMAC<\/jats:styled-content>), and range of motion (ROM<\/jats:styled-content>) indices were assessed. Any complications or requirements for total knee arthroplasty (TKA<\/jats:styled-content>) were investigated. Mechanical axis (MA<\/jats:styled-content>), minimal joint space width (mJSW<\/jats:styled-content>) and Pettersson score were measured. Bone union rates at 3 and 6\u00a0months postoperative were evaluated.<\/jats:p><\/jats:sec>Results<\/jats:title>VAS improved from 5.1 to 2.4 (P\u00a0<\/jats:italic><\u00a0.001). WOMAC<\/jats:styled-content> was 66.5 preoperatively, and 26.6 postoperatively (P<\/jats:italic>\u00a0<\u00a0.001). Pre\u2010 and postoperative ROM<\/jats:styled-content> did not differ significantly. There were no cases of HTO<\/jats:styled-content> converted to TKA<\/jats:styled-content>, but one case of HTO<\/jats:styled-content> required TKA<\/jats:styled-content> 152\u00a0months postoperative. No complications were observed. The MA<\/jats:styled-content> was corrected from varus 5.1\u00b0 to valgus 1.2\u00b0 (P<\/jats:italic>\u00a0<\u00a0.001). Pre\u2010 and postoperative mJSW<\/jats:styled-content> did not significantly differ. Pettersson score improved from 3.84 to 2.47 (P<\/jats:italic>\u00a0<\u00a0.001). The bone union rates at the osteotomy gap were 45.2% and 67.8% at 3 and 6\u00a0months postoperative.<\/jats:p><\/jats:sec>Conclusions<\/jats:title>Open\u2010wedge HTO<\/jats:styled-content> should be considered in cases of HA<\/jats:styled-content> with varus deformity in young haemophilic patients, even though inflammatory arthritis is not an optimal indication for this procedure.
