Description of the modified MOCART score
| Variable | Class | Score |
|---|---|---|
| Degree of defect repair and defect filling | Complete (on a level with adjacent cartilage) | 20 |
| Hypertrophy (over the level of the adjacent cartilage) | 15 | |
| Incomplete (under the level of the adjacent cartilage: underfilling) | ||
| >50 % of the adjacent cartilage | 10 | |
| <50 % of the adjacent cartilage | 5 | |
| Subchondral bone exposed (complete delamination or dislocation and/or loose body) | 0 | |
| Integration to border zone | Complete (complete integration with adjacent cartilage) | 15 |
| Incomplete (incomplete integration with adjacent cartilage), demarcating border visible (split-like) | 10 | |
| Defect visible | ||
| <50 % of the length of the repair tissue | 5 | |
| >50 % of the length of the repair tissue | 0 | |
| Surface of the repair tissue | Surface intact (lamina splendens intact) | 10 |
