From: Finite element analysis of the valgus knee joint of an obese child
Finite element model and model geometry of the knee joints. a Finite element model of the knee valgus child’s left knee. b Finite element model of the healthy child’s left knee. c The model geometry of natural walk with knee flexion angle 1 and ankle flexion angle 2. Loads were applied on the distal end of the tibia and fibula
