Fig. 1A. 14-year-old girl with osteochondritis dissecans of
anterolateral right femoral condyle. Sagittal spin-echo proton
density-weighted MR image (TR/TE, 2400/20) shows ovoid low-signal-intensity
lesion of anterolateral femoral condyle (arrows).

Fig. 1B. 14-year-old girl with osteochondritis dissecans of
anterolateral right femoral condyle. Axial CT scan shows irregular subchondral
margin. Subchondral cysts (arrow) are present.

Fig. 2A. 24-year-old man with chronic patellofemoral pain. Axial
radiograph of knees shows bilateral osteochondritis dissecans involving
lateral aspects of each femoral sulcus (arrows).

Fig. 2B. 24-year-old man with chronic patellofemoral pain. Axial
fat-suppressed fast spoiled gradient-echo MR image (TR/TE, 18.8/2; flip angle,
30°) of left knee shows irregularity of subchondral bone of lateral sulcus
(arrow). Articular cartilage was intact, and lesion was stable at
arthroscopy (not shown).

Fig. 3A. 16-year-old boy with osteochondritis dissecans of
anterolateral left femoral condyle. Sagittal spin-echo proton density-weighted
MR image (TR/TE, 2000/20) shows low-signal-intensity lesion in anterolateral
femoral condyle.

Fig. 3B. 16-year-old boy with osteochondritis dissecans of
anterolateral left femoral condyle. Sagittal spin-echo T2-weighted MR image
(2000/70) shows high-signal interface (arrows) between
osteochondritic fragment and femur, indicating unstable lesion.

Fig. 4. 17-year-old boy with osteochondritis dissecans of
anterolateral left femoral condyle. Sagittal fast spin-echo proton
density-weighted MR image (TR/TE, 3500/8.1) shows loose body (straight
arrow). Donor site is at anterior aspect of lateral femoral condyle
(curved arrow).

Fig. 5A. 28-year-old man with osteochondritis dissecans of
anterolateral left femoral condyle. Sagittal fast spin-echo proton
density-weighted MR image (TR/TE, 4316/20) shows subchondral fragmentation and
cyst formation.

Fig. 5B. 28-year-old man with osteochondritis dissecans of
anterolateral left femoral condyle. Sagittal fast spin-echo inversion recovery
MR image (TR/TE, 5300/72; inversion time, 150 msec) shows high-signal
interface between osteochondritic fragment and femur as well as subchondral
cysts (arrow), consistent with unstable lesion. Bone marrow edema is
present at femur deep relative to osteochondral lesion. Joint effusion is
present.

Fig. 6A. 13-year-old boy with osteochondritis dissecans of
anterome-dial right femoral condyle. Sagittal fast spin-echo proton
density-weighted MR image (TR/TE, 3500/8.1) shows flattening and irregularity
of femoral condyle (arrow).

Fig. 6B. 13-year-old boy with osteochondritis dissecans of
anterome-dial right femoral condyle. Axial fast spin-echo proton
density-weighted MR image (4200/49.6) with fat saturation shows extensive
femoral bone marrow edema (curved arrow). Presence of subchondral
cysts suggests that this is unstable lesion. Loose body (straight
arrow) is identified adjacent to posteromedial femoral condyle. Joint
effusion is present.
