The MOCART scoring system
| Variable | Classes |
|---|---|
| Degree of defect repair and defect filling | Complete (on a level with adjacent cartilage) |
| Hypertrophy (over the level of the adjacent cartilage) | |
| Incomplete (under the level of the adjacent cartilage; underfilling) | |
| >50% of the adjacent cartilage | |
| <50% of the adjacent cartilage | |
| Subchondral bone exposed (complete delamination or dislocation and/or loose body) | |
| Integration to border zone | Complete (complete integration with adjacent cartilage) |
| Incomplete (incomplete integration with adjacent cartilage) | |
| demarcating border visible (split-like) | |
| Defect visible <50% of the length of the repair tissue | |
| >50% of the length of the repair tissue | |
| Surface of the repair tissue | Surface intact (lamina splendens intact) |
