This invention concerns a biomimetic material based on energy-rich amorphous magnesium polyphosphate (Mg-polyP) microparticles that enhance cartilage synthesis and regeneration. One preferred formulation of the inventive material is a hyaluronic acid-Mg / Ca-polyP paste that can be produced from a water-soluble salt of polyP and water-soluble hyaluronic acid in the presence of water-insoluble / nearly insoluble calcium carbonate.
