The effect of fixed charge density and cartilage swelling on mechanics of knee joint cartilage during simulated gait

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 FCD was investigated on the internal collagen fibri...
