The hallmark feature of osteoarthritis is the breakdown in the anudar cartilage of joints such as the knee and hip. Increased T2 is virtually all commonly associated with cartilage damage; yet , low-signal-intensity lesions that may be because of increased water interaction with molecular fragments in cartilage are seen in some cases. Although T2 maps can be used to differentiate normal areas of cartilage from parts of deterioration, there does not appear to be any linear relationship among T2 and osteoarthritis grade that could aid differentiation between mild and more severe disease ( 42 tommers skærm ). Furthermore, physical activity seems to play a role in cartilage T2 values ( 53 ).
Marrow stimulation - underneath the ruined cartilage, the surgeon drills tiny holes (micro-fractures), revealing the blood vessels that lie inside the bone tissue. This causes a bloodstream clot to form inside the cartilage that triggers the availab
