Does cartilage grow appositionally and interstitially?

Cartilage grows both appositionally and interstitially. Appositional growth occurs at the outer surface, where new cartilage is added by chondroblasts in the perichondrium. Interstitial growth happens from within the cartilage itself, as chondrocytes divide and secrete new matrix, leading to an increase in cartilage size. Both mechanisms contribute to the overall growth and maintenance of cartilage tissue.
