Cartilage calcification generally speaking refers to the accumulation of a lot of calcium in the cartilage area, followed by a calcified mass of cartilage, which later leads to cartilaginous bone changes. In case of cartilage calcification, the cartilage becomes diseased and such a lesion is divided into two cases, physiological and pathological. there are three processes of cartilage calcification: 1. it is calcification seen around the cartilage cells, which is usually the case before calcification. 2. the process of calcification expands along the collagen fibers within the tissue, gradually filling the collagen fibers with calcium around them and causing calcification of the collagen fibers. 3. endochondral ossification, which is only in the cartilage Formation of calcification foci or calcification, small sugar lumps gradually increase or become larger, the entire cartilage completely formed calcified bone, such a situation is mostly seen between the chondrocyte column, stimulating the formation of bone crystals, and finally bone formation. Therefore, in layman’s terms, cartilage calcification is a process in which cartilage gradually becomes bone due to the deposition of calcium.
