This research studies behavior of ligament reconstruction on knee while walking using the integration of dynamics motion analysis and finite element analysis. The purpose is to calculate stress and strain distribution on single and double bundle reconstruction while walking. First, ligament reconstruction is tested to obtain mechanical properties, which are used for finite element analysis. Next, 3D CAD model and finite element model are constructed. Dynamics motion analysis of femur and tibia while walking is introduced. The degrees of hip and knee motion with respect to time are resulted of dynamics analysis and set as load for finite element analysis. The stress and strain on knee’s ligament reconstruction while walking are calculated by finite element method. The maximum stress and strain occur on a top of ligament while extend leg are 33.86 MPa and 0.153 mm/mm, respectively, for single hamstring bundle. The maximum stress is 43.82 MPa and maximum strain is 0.188 mm/mm for double hamstring bundles. The advantage is to understand the biomechanics of the knee ligament reconstruction while walking. This research result can help patients who have tear problem of an Anterior Cruciate Ligaments (ACL) or stroke rehabilitation and be developed for further research about force and behaviors of the other ligament and muscle in body.
