TABLE I.

Arthroscopic (ICRS) Grading of Cartilage Repair*

Points
Degree of defect repair
 Level with surrounding cartilage 4
 75% of defect depth 3
 50% of defect depth 2
 25% of defect depth 1
 0% of defect depth 0
Integration to border zone
 Complete integration with surrounding cartilage 4
 Demarcating border <1 mm 3
 3/4 of graft integrated with surrounding cartilage, 1/4 with notable border of >1 mm 2
 1/2 of graft integrated with surrounding cartilage, 1/2 with notable border of >1 mm 1
 From no contact to 1/4 of graft integrated with surrounding cartilage 0
Macroscopic appearance
 Intact smooth surface 4
 Fibrillated surface 3
 Small, scattered fissures or cracks 2
 Several small or few but large fissures 1
 Total degeneration of grafted area 0
Overall repair assessment
 Grade I: normal 12
 Grade II: nearly normal 8-11
 Grade III: abnormal 4-7
 Grade IV: severely abnormal 1-3
*

The maximum possible score is 12 points, and a higher score is better.
