Examination of case 9 revealed ICRS OCD III. The cartilage was fixed by four 6-mm diameter osteochondral plugs (13 mm length) harvested from the ipsilateral lateral condyle (a). Two-month postoperative radiographs of case 9 demonstrated apparently smooth joint congruity and an open physis (b, c). Coronal T1-weighted (d) and sagittal T1-weighted (e) MRI of the knee performed 2 months later showed that the intensity of the lesion was similar to that of the surrounding normal articular cartilage, but an interface still existed between the plugs and subchondral bone
