Characteristic | Magnetic resonance imaging score | |||
|---|---|---|---|---|
| Â | 1 (normal) | 2 (mild) | 3 (moderate) | 4 (abnormal) |
Defect filling | 11 (complete filling), including 3 with minimal hypertrophic changes (<125%) | 5 (>50%) | 1 (<50%) | 0 (no filling) |
Signal intensity | 8 (normal) | 8 (some hyperintense areas) | 1 (hyperintense areas) | 0 (no signal) |
Subchondral edema | 4 (no edema) | 7 (mild edema) | 5 (moderate edema) | 1 (distinct edema) |
Effusion | 1 (no effusion) | 11 (mild effusion) | 4 (moderate effusion) | 1 (distinct effusion) |
