Abstract

Cartilage cells are present in all of the articular cartilages, they form the matrix, and function to maintain the cartilages. As articular cartilages are avascular, superficial injury can therefore not induce a sufficient inflammatory reaction in other to cause regeneration. Upon injury, the regeneration capacity of cartilage is limited and injury induces degeneration of the fibrillar organization of collagens.
