Purpose: The aim of this study is to evaluate clinical and radiological results of simultaneous bilateral correction of genu varum with Smart frame. Methods: Between 2011 and 2015, a total of 25 patients (10 females, 15 males) who had bilateral genu varum deformity were operated bilaterally with tibial and fibular osteotomy in the same session, using Smart frame. The mean follow-up period was 28.7 (range, 13-45) months. All patients had bilateral tibial varus deformity. Femoral deformity was corrected in an earlier session in nine patients. Mechanical axis deviation (MAD), mechanical lateral distal femoral angle, mechanical medial proximal tibial angle (mMPTA) and posterior proximal tibial angle (PPTA) were measured preoperatively and postoperatively. Short Form-36 questionnaire was filled by the patients preoperatively and during the last follow-up. Results: The mean preoperative MAD was 37.6 mm (range, 9-98 mm), which improved to 8.4 mm (range, 3-44 mm) postoperatively (p < 0.05). The mean preoperative mMPTA was 76 degrees, which improved to 89 degrees (p < 0.05). The mean preoperative PPTA was 75.5 degrees, which improved to 80.3 (p < 0.05). Ten problems (20%), two obstacles (4%) and no sequelae occurred in 50 legs of 25 patients. Conclusions: In conclusion, Smart frame is an accurate and reliable method for performing bilateral simultaneous deformity correction in patients with bilateral genu varum deformity. It can be applied for various childhood-induced severe tibial deformities such as achondroplasia, rickets, skeletal dysplasia and Blount's disease.
