The mechanical functions of regenerated cartilage are expected to be equivalent to those of natural cartilage. Articular cartilage keeps sliding with low friction over changes in the mechanical environment. In this research, we have investigated lubrication properties of regenerated cartilage with fibroin-sponge over changes of applied load. The frictional experiments showed that friction coefficient of regenerated cartilage increased with sliding distance due to exudation of proteoglycan near the surface, and in such state the friction coefficient decreased with the increase of applied load. The results suggested that the transitions of friction coefficient with the increase of applied load mainly depend on the behaviour of proteoglycan to changes of the pressure.
