FINITE ELEMENT MODELING OF THE OSTEOCHONDRAL DEFECTS IN THE HUMAN KNEE: INFLUENCE OF DEFECT SIZE ON CARTILAGE RIM STRESS AND LOAD REDISTRIBUTION TO ADJACENT CARTILAGE

摘要

The purpose of this study was to determine the influence of osteochondral defect size on defect rim stress concentration, and load redistribution to adjacent cartilage over the weight-bearing area of the medial and lateral femoral condyles in the human knee Subsequent finite element (FE) computer modeling of these defects was designed to determine the deformation of the underlying cartilage and to further analyze the development of rim stress.
