|Abstract:||Medial opening-wedge has gained popularity in comparison to other techniques of high tibial osteotomy. This technique involves the creation of a gap in the tibia. Filling the gap with autologous iliac bone graft was recommended in the classic description, to prevent complications such as correction loss or delayed bone union. No previous reports have compared grafted and nongrafted osteotomies. This study hypothesized that the use of autologous bone graft in medial opening-wedge high tibial osteotomy (MOWHTO) less than 12.5mm is unnecessary. A prospective randomized clinical trial was conducted. Forty-six opening-wedge high tibial osteotomies were carried out between April 2007 and December 2008. All had fixation with a type of Puddu stainless steel plate and screws. Patients were randomly divided by software analysis into two groups: group A had osteotomies that were filled with autologous bone graft and group B had osteotomies that were unfilled. Autologous iliac bone graft was harvested in both groups. Clinical and radiographic evaluations were performed twice monthly by blinded investigators. The rates of complications were compared between the groups. There was no difference in demographic data. Mean time to clinical bone union in group A was 12.4 weeks (confidence interval [CI] 11.2-13.6) and in group B was 13.7 weeks (CI 12.5-14.9), but this difference was not significant (P=0.13). Signals of correction loss occurred in one patient (4.35%) in group A, and in two patients (8.70%) in group B. All osteotomies had achieved bone union. It was concluded that time to bone union was not statistically different between the group with bone graft and the group without graft. © 2010, © the Authors.
