Clinical and radiologic results after open‐wedge high tibial osteotomy in haemophilic knee arthropathy with varus deformity

Introduction The previous studies have described only closed‐wedge high tibial osteotomy (HTO) in haemophilic arthropathy (HA). Aim The purpose of this study was to evaluate clinical and radiographic results after open‐wedge HTO in HA with varus knee deformity. Methods We included 13 open‐wedge HTOs in HA performed between 2005 and 2016. The mean age of patients was 28.9 years. Visual analogue scale (VAS), Western Ontario and McMaster Universities (WOMAC), and range of motion (ROM) indices were assessed. Any complications or requirements for total knee arthroplasty (TKA) were investigated. Mechanical axis (MA), minimal joint space width (mJSW) and Pettersson score were measured. Bone union rates at 3 and 6 months postoperative were evaluated. Results VAS improved from 5.1 to 2.4 (P
