📌Signs of Osteochondral Lesion Instability in Adults

• The presence of any one sign indicates instability in adult OCD, with the most frequent finding being an underlying high-signal-intensity line.

 

✅ High-Signal-Intensity Rim

• A high-signal-intensity rim at the interface between the fragment and the adjacent bone on T2-weighted MR images.

 

✅Fluid-Filled Cysts

• Fluid-filled cysts beneath the lesion.

• Cysts surrounding a juvenile OCD lesion indicate instability only if they are multiple or larger than 5 mm.

 

✅ High-Signal-Intensity Line

• A high-signal-intensity line extending through the articular cartilage overlying the lesion.

✅ Focal Osteochondral Defect

• A focal osteochondral defect filled with joint fluid, indicating complete detachment of the fragment.
