GROSS OCD LESION DESCRIPTION – CUE BALL

Illustration

Arthroscopic Image

Need image

0 - No abnormality detectable arthroscopically

IMMOBILE Lesion

1 - Congruent

2 - Incongruent

3 - Fragmented

4 - Absent

1 - Congruent

2 - Incongruent

3 - Fragmented

6 - Exposed sub-chondral bone defect

Congruent = fragment fits into crater without modifications

Incongruent = fragment fits into crater with modifications
