MR imaging after successfully treatment with BMC. a - c MR imaging of the 16-years-old boy before (a, b) and after surgery (c, d, 12 months postoperatively). PD-weighted (a, b) and T1-weighted (c, d) sequences demonstrate no subchondral bone erosion or fracture, normal contour of the epiphyseal head and preservation of the joint space. Proton density-weighted (a, b) sequences demonstrate mostly hematopoietic marrow without cystic or fibrotic lesion
