Evaluation of uniplanar and biplanar valgus distal femoral osteotomy of patients with genovarum deformity

Abstract

Both uniplanar and biplanar methods have been proposed for distal femur osteotomy. Although in the recent studies comparing uni-planar and bi-planar methods, brief results have been in favor of the bi-planar method, but the number of these studies is small and weak in terms of validity, and it seems that the decision regarding The preference of the two mentioned methods is still difficult; Therefore, the purpose of this study is to investigate two uni-planar and bi-planar methods in distal femur surgeries as a clinical trial. Materials and Methods: This study is a randomized and double-blind clinical trial, after obtaining the code of ethics in Shahada and Imam Reza hospitals, with the participation of 50 patients with genovaroma, whose deformity originates from the femur, and who are candidates for distal femur osteotomy. ,Done. Patients will be placed online in two groups, uni-planar and bi-planar, and based on the type of grouping, they will undergo surgery by a single surgeon and will be followed up for 12 months. Patients underwent clinical and radiological evaluation every month until the fusion of the stoma site, in terms of fusion status, deformity correction status, and postoperative complications, and at the end of one year, the results of the two methods were evaluated with the help of 2000 IKDS and KOOS tests. KSS was evaluated. The results between the two groups were compared with the help of descriptive and inferential statistics tests. Results: The rate of improvement in patients of the biplanar group (P=0.069) was insignificantly better than that of the uniplanar group (P=0.078); But the results of the varus angle in the ionic planar group (P=0.003) compared to the biplanar (P=0.009), ROM variable in the ionic planar group (P=0.042) compared to the biplanar (P=0.042) ) and Flex variable in uniplanar group (P=0.035) compared to biplanar group (P=0.041) had insignificantly better results. Examining the results of the total scale and subscales in the KOOS and KIDS questionnaires indicated that in all cases the results of uniplanar surgery were insignificantly better than the results of biplanar surgery. The duration of union, hematoma formation and infection in the patients of the biplanar group were insignificantly more than those of the uniplanar group, while the number of people with non-union in the patients of the uniplanar group was nonsignificantly more than the patients of the biplanar group. The intensity of pain in patients of the biplanar group was insignificantly higher than the intensity of pain in the patients of the uniplanar group. Satisfaction was significantly higher in patients who underwent uniplanar surgery (P=0.048) than patients who underwent biplanar surgery.
