Table 1 Outerbridge classification.
| Grade | Macroscopy | MRI |
|---|---|---|
| Grade 0 | Normal cartilage | Normal cartilage |
| Grade 1 | Rough surface; chondral softening, focal thickening | Inhomogenous; high signal; surface intact; cartilage swelling |
| Grade 2 | Irregular surface defects; | Superficial ulceration, fissuring, fibrillation; |
| Grade 3 | Loss of >50% cartilage thickness | Ulceration fissuring, fibrillation; >50% of depth of cartilage |
| Grade 4 | Cartilage loss | Full thickness chondral wear with exposure of subchondral bone |
