Cartilage is a quite incredible substance. Articular cartilage does certainly not have pain fibers and as a result the pain symptom are not equally proportional to the amount of injury in some cases. Therefore, it is possible for the articular the cartilage lesion to be minimally painful in some situations. Usually minor aches and stiffness may be the only warning of a great articular cartilage injury. In general the larger and deeper the lesion the higher the pain.
The reaction patterns of chondrocytes in osteoarthritis can end up being summarized in five groups: (1) proliferation and cellular death (apoptosis); changes in (2) synthetic activity and (3) degradation; (4) phenotypic modulation from the articular chondrocytes; and (5) formation of osteophytes. In osteoarthritis, the primary responses are reinitiation of synthesis of the cartilage macromolecules, the initiation of synthesis of types IIA and III procollagens as markers of an additional 4 flex na stawy opinie primitive phenotype, and synthesis of active proteolytic enzymes. Reversion to a fibroblast-like phenotype, known as 'dedifferentiation', does not appear to be an important component. Proliferation plays a role in forming characteristic chondrocyte groupings near the surface, while apoptosis probably occurs mostly in the calcified cartilage.

Proteoglycans are synthesized, maintained, and secreted into the ECM by chondrocytes. A quantity of growth factors and regulatory peptides have been implicated in the regulation of proteoglycan metabolism, including insulin-like growth factors, transforming development factor−β, interleukin-1, and tumour arthryl tabletki necrosis factor−α. Very little is known about the molecular mechanism in which these growth factors and peptides elicit their effects about proteoglycan metabolism.
Although an articular cartilage split isn't life threatening, that can significantly affect the top quality of life of the person with the injury. Soreness, swelling of tissues, constrained activities, and reduced range of motion are common with anudar cartilage tears By fixing the tissue after harming the articular cartilage, these negative effects can end up being greatly reduced.
