We planned a recorrection osteotomy because the patient led an active lifestyle, had well-preserved range of motion and the lateral compartment was still intact. According to preoperative deformity analysis, which indicated a tibia in slight valgus and a femur in moderate varus, recorrection of the distal femur was chosen. Seven degrees of biplanar distal femoral osteotomy (DFO) was performed using a contralateral version of the TomoFix Medial Distal Femur. At 1\u2009year follow-up, the femorotibial angle had improved from 178\u00b0 to 170\u00b0, and the Japanese Orthopaedic Association score had improved from 75 to 95 points. Additional DFO could be a viable alternative for total knee arthroplasty or recorrection HTO when the centre of the deformity is located at the distal femur.<\/jats:p>","DOI":"10.1136\/bcr-2018-224514","type":"journal-article","created":{"date-parts":[[2018,8,27]],"date-time":"2018-08-27T11:09:09Z","timestamp":1535368149000},"page":"bcr-2018-224514","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":2,"title":["Additional
