عنوان انگلیسی Single Cut Distal Femoral Varus Osteotomy (SCFO): A Preliminary Study
چکیده انگلیسی مقاله Background: Genu valgum usually originates from a deformity of distal femur that is often corrected by distal femoralvarus osteotomy. The osteotomy includes both components of angulationcorrection and translation because the siteof osteotomy is not commonly at the apex of deformity. Improvement of patellar tracking not only depends on valguscorrection, but also it may be partially due to centralization of the trochlear groove under the femoral anatomical axis(FAA).We asked whether we could accurately correct the deformities based on our preoperative goals for the correction ofthe mechanical axis and centralization of the trochlear groove under the FAA by using a single bone cut.This study describes a new lateral single cut distal femoral osteotomy (SCFO) that enables concurrent correction ofangulation and translation.Methods: This study was done on 12 young adult patients with femoral juxta-articular genu valgum deformityusing SCFO. The average age at operation was 21 years (range: 16-25). SCFO is a type of closing-openingdistal femoral osteotomy that corrects the valgus deformity of the distal femur while the translation of the distalfragment is done using one oblique cut. It centralizes the trochlear groove under the FAA. We compared the preand postoperative radiographic and clinical variables including mechanical tibiofemoral angle, knee range of motion(ROM), International knee documentation committee (IKDC) score and the time to ::union::. Mean follow-up of thepatients was 24 months.Results: The average mechanical tibiofemoral angle improved from 16 degrees (10-23) to 1 degrees (-2 to +2). IKDCsubjective score slightly improved from preoperative (65) to 2-year follow-up (71). Centralization of the trochlea wasachieved in all patients.Conclusion: SCFO can be a reasonable alternative for correction of the distal femur genu valgum deformity. It cancentralize the patellar groove under the FAA with satisfactory clinical outcomes.
