Result: 174/215 (80.9 percent) symptomatic hip joins, 72.4 percent hip joins with severe pain. Pain rate was highest In late stage of the disease and in class D on MRI. 70 percent hip had necrosis lesion area of the femoral head over 30 percent. 97.5 percent subchondral radiolucency hips and 98.3 percent collapsed hips that had symptom. 112 (88.9 percent) hips showed bone marrow edema and 92.9 percent joint effusion on MRI had severe pain.
