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.
