FINITE ELEMENT ANALYSIS OF HUMAN AND ARTIFICIAL ARTICULAR CARTILAGE

Joint diseases, such as osteoarthritis, induce pain and loss of mobility to millions people around the world. Current clinical methods for diagnosis osteoarthritis include X-ray, magnetic resonance imaging, arthroscopy. These may be insensitive earliest signs osteoarthritis. This study investigates a new procedure that was developed validated numerically use in evaluation cartilage quality. finite element model human articular could helpful providing insight into mechanisms injury, effects treatment, role mechanical factors degenerativeconditions, this three-dimensional is useful tool understanding stress distributions within response external loads investigating both prevention injury pathological degeneration joints.In study, 21 models were analysed by using ANSYS workbench v12.1: four normal (distal femur, patella, medial lateral tibia). A redesign distal femur done get (simple deep) seven making partial cut without affecting subchondral bone, full with part bone different diameters. Finally treatment replacing defective parts artificial cartilages types treatment. The analysis studied depending on Von Mises criteria total deformation activities. results shows Autologous Chondrocyte Implementation best way it close 87.50% cartilage. can used diagnostic osteoarthritic patients choose options.
