A 13-year-3-month-old female with FOPE zones at both proximal tibiae. Findings: coronal proton density fat-saturated image from follow-up of right knee MRI obtained 6 months after initial MRI shows decrease in the marrow edema surrounding the osteochondral lesion of the medial femoral condyle. The osteochondral lesion (arrow) is otherwise unchanged in appearance. Technique: coronal PD fat-saturated MRI (TR = 2,472.4, TE = 30), ST = 2.5 mm, spacing = 3.3 mm, FOV = 14 cm, and matrix = 312 × 244.
