Open Wedge High Tibial Osteotomy with Aescula® Plate

Purpose: This study is to evaluate chinical and radiological results of open wedge high tibial osteotomy using Aescula plate. Materials and Methods: Ninity one patients who have unicompartmental osteoarthritis with varus deformity were treated by open wedge high tibial osteotomy with Aescula plate and followed up at least 2 years. Clinically, visual analogue scale (VAS), range of motion (ROM) and hospital for special surgery (HSS) score were evaluated. Radiologically, tibio-femoral angle, mechanical axis, medial proximal tibia angle and posterior slope were measured. All complications were also evaluated. Results: During the follow-up VAS improved from 8.3 to 2.1, ROM were checked preoperatively from to and from to at last follow up. And HSS score improved from 76.8 to 91. Preoperative tibio-femoral angle was of varus, mechanical axis of varus, medial proximal tibia angle and posterior slope . Radiologic results at last follow up revealed significant improvements by of valgus for tibio-femoral angle, of valgus for mechanical axis and for medial proximal tibia angle. Mean posterior slope was 1 which increased compared with preoperative one. And there was one fixation failure that needed re-operation. Conclusion: Open wedge high tibial osteotomy using Aescula provided excellent clinical and radiological results at 2 years follow-up.
