    Abstract:
    An experimental technique was developed for measuring the swelling-induced strains in articular cartilage while attached to the subchondral bone, a configuration more representative of the in vivo state than excised cartilage. The cartilage attachment to the bone greatly limits the free swelling effect in which the strains observed were much smaller than those for excised tissue samples. The components of swelling strain varies from compressive at the deep zone to tensile at the middle-surface zones. Periods of immobilization produced an increase in strains which was not related to a change in either water volume fraction or fixed charge density.
