The aim of this study is to investigate the influences of subchondral thickness on frictional behavior of articular cartilage. It was found that friction coefficient increased with decrease of the ratio of the thickness of subchondral and eancellous layer to that of cartilage layer. In addition, frictional behavior of natural cartilage is affected significantly when the ratio of the thickness of subchondral and cancellous layer to that of cartilage layer is less than 1.0. It was found that there were little differences in apparent contact area and surtace tnoiphology between cartilage specimen with and without subchondral and cancellous layer. It is hypothesized that the thickness of subchondral and cancellous layer influences on the tranfer of water in cartilage layer and between cartilage layer and subchondral layer, and thus internal stress and hydration behavior of cartilage layer changes. These changes may induce the changes of frictional behavior of natural cartilage.
