The simulation of mechanical states of repaired articular cartilage
Though cartilage tissue is susceptible to damage anddifficult to self-repair, cartilage tissue engineering provides anideal way for the treatment of cartilage defects. Mechanicalenvironments have significant effects on the growth anddevelopment of cartilage. The research of mechanical states ofrepaired articular cartilage by tissue engineering hassignificantly clinical value. According to the physical structureand movement modes of the knee, a model for the treatment ofcartilage defects by tissue engineering was established based on the finite element method, with a rolling depression load as themechanical condition. Defect models of articular cartilage wererepresented by three different indicators: defect width, depth and the elastic modulus of artificial cartilage implanted. By finiteelement simulating, we theoretically studied the mechanical statesof articular cartilage repaired by tissue engineering. The resultsshow that the mechanical states varied in different parts of thedefect, and some stresses in the tissue engineered cartilage or hostcartilage deviated obviously from normally physiologicalconditions of the knee. An artificial cartilage with certainmechanical properties may contribute to the repair of cartilagedefects by tissue engineering.
