The Effects of Proximal Fibular Osteotomy on the Knee and Ankle Joints: a Finite Element Analysis

PURPOSE OF THE STUDY In this study, our aim is to examine the effect of proximal fibular osteotomy on knee and ankle kinematics with finite element analysis method. MATERIAL AND METHODS One 62-year-old, female volunteer's radiologic images were used for creating lower limb model. Osteotomized model (OM) which was created according definition PFO non-osteotomized (NOM) created. To obtain a stress distribution comparison between two models, 350 N axial force applied femoral heads models. RESULTS After PFO, average contact pressure decreased 26.1% at medial tibial cartilage increased 42.4% lateral cartilage. The Von Mises stresses 57.1% 79.1% 44.6%, talar 7.1% joint. CONCLUSIONS FEA revealed that main loading joint shifted from after PFO. Additionally, each redistributed across wider more peripheral area. also demonstrated cartilages Key words: pain, osteoarthritis, osteotomy, analysis, loadings.
