The descriptions of criteria used in meniscal scoring.

Score	Striation	Discoloration	Deformation	Tearing	Quality
0	faint	none	none	none	non- degenerative
1	dark; thick	focal	present	none; partial	non- degenerative
2	np	np	np	complete; non-complex	non/low degeneracy
3	np	np	np	complete; complex	moderate degeneracy
4	np	np	np	np	complete structural loss

The initial scoring framework is as described by OARSI (Cook et al. 2010). Striation, discoloration, and deformation were the additional criteria used in scoring. Descriptions from the previous score may or may not be preexisting features. ‘np’ indicates non-pertinent criteria for scoring since more severe damage elicits a higher score.
