Cartilage exhibits an extremely low friction and very wearability within the liquid environment of joint. It is also capable switching wettability between superhydrophilicity hydrophobicity in both wetting dry conditions (specific experimental operations or open wounds). Therefore, understanding cartilage lubrication from perspective provides inspiration for design artificial sections with motion soft actuators coefficients (COF). In this review, articular introduced discussed view wettability. First, basic principles are described a focus on compositions cartilage, particular relationship phospholipid layers supramolecular synergy synovial fluid cartilage. Subsequently, under different stimuli (such as shear, pH, temperature, electric field) insights into lubrication. Finally, we present comprehensive summary delineate challenges domain assisting researchers formulating viable concepts efficient substitution smart lubricating devices.
