Abstract

The negatively charged cartilage surface is supported by smart slippage lamellar-repulsive lubrication. The surface amorphous layer (SAL) covers the natural surface of articular cartilage. The friction is largely associated with charge density by electrostatic repulsion between the two cartilage surfaces. At pH 7.4 (± 1) we observed stable and low friction coefficient. This study examined the frictional conducting of the normal articular cartilage in relation to the surface of unhealthy one. Following sliding tests of a (cartilage/ cartilage) the worn surfaces wettability and friction coefficient were studied. It is concluded that the phospholipids bilayers formation, a lubricant influenced the friction performance.
