Fibrocartilage is stiff and contains many collagen fibers type I and II, while hyaline cartilage is a soft cartilage that contains collage fibers type I. Fibrocartilage contains only few chondrocytes in lacunae, while hyaline cartilage has large number of them. As a result, fibrocartilage provide a restricted mobility, while hyaline cartilage enables smooth movements.
