RESUMO
High tibial osteotomy methods include open and closed wedge techniques. The study aims at comparing results of osteotomy methods in patients suffering from genu varum deformity. In a cohort study, 32 patients with genu varum deformity (42 knees) were evaluated. They were divided into two groups and matched according to age and gender. The patients were treated with open and closed wedge osteotomy. After surgery, they were followed up and compared for 6 months. Thirty two patients with genu varum deformity (10 cases of bilateral deformity (31.2%) including 25 women (87.2%) and 7 men (21.8%) were studied. Incidence of complications was the same after open and closed wedge osteotomy operation (12.5%). Patients overall satisfaction from open and closed wedge methods was 87.5 and 75%, respectively. There was statistically significant difference between two groups considering operation duration, weight bearing duration and return to routine activities (p < 0.001). There was no difference in other parameters including varus angle correction, Lysholm score Tegner activity as well as Insall Salvati index. This study demonstrated that there is no difference between two osteotomy methods considering patients' clinical outcomes and both methods are successful in final treatment results.
