Abstract
Background: Genu valgum deformity is defined as a mechanical axis deviation (MAD) lateral to the knee joint center. In this situation the lateral compartment of the knee is overloaded. Corrective osteotomies are recommended to realign the lower extremity. Objectives: This study was designed to evaluate the lateral distal femoral biplanar open wedge corrective osteotomy results in patients with genu valgum. Patients and Methods: This is a case-series study on seven patients. All patients had genu valgum deformity and medial thrust or pain in the lateral compartment. Lateral biplanar distal femoral open wedge osteotomy was used as corrective osteotomy. Radiological findings and union time at the osteotomy site of the operated patients was determined. Results: All patients were female. The mean age was 25.14 ± 4.74. The mean follow up time for these patients was 8.28 ± 6.96 months. The mean preoperative mechanical alignment was 8.71 ± 2.21 while the post-operative was 1.42 ± 0.53. The mean wedge size used for osteotomy was 8.71 ± 2.21 mm. The mean union time was 9.71 ± 2.56 weeks. Conclusions: Stability and early union without using bone graft at the osteotomy site, rapid rehabilitation and weight bearing of patients with genu valgum are the advantages of biplanar lateral distal femoral open wedge osteotomy.
