Medial opening-wedge high tibial osteotomy is one of the common surgical procedures in treatment of knee deformities. Many methods have been proposed to fill the medial side osseous gap. The results of using allograft as void filler compared to iliac crest autograft has not been subject to a randomized clinical trial. The purpose of this study was to examine the results of medial opening-wedge high tibial osteotomy using iliac crest allograft as compared to iliac crest autograft. Forty-six patients with genovarum deformity were enrolled based on specific inclusion and exclusion criteria and were randomly assigned into two groups. Medial opening-wedge high tibial osteotomy was done using iliac crest allograft (23 patients) or autograft (23 patients) and the osteotomy site was internally fixed using proximal tibial T-plate. All patients were followed-up to 12 months after surgery. Anatomical indices of proximal tibia, complications of treatment, and functional outcome (using WOMAC osteoarthritis index) were assessed for both groups.Background
