The effect of swelling of articular cartilage, caused by the fixed charge density (FCD) of proteoglycans, has not been demonstrated on knee joint mechanics during simulated walking before. In this study, the influence of the depth-wise variation of F

Three dimensional patient-specific collagen architecture modulates cartilage responses in the knee joint during gait

Autor: Jukka S. Jurvelin, Lasse P. Räsänen, Mika E. Mononen, Miika T. Nieminen, Rami K. Korhonen, Eveliina Lammentausta

Site-specific variation of collagen fibril orientations can affect cartilage stresses in knee joints. However, this has not been confirmed by 3-D analyses. Therefore, we present a novel method for evaluation of the effect of patient-specific collagen

Focal cartilage lesions can proceed to severe osteoarthritis or remain unaltered even for years. A method to identify high risk defects would be of utmost importance to guide clinical decision making and to identify the patients that are at the highe
