Repair does exist; a majority of a panel of experts judged the follow-up image to be better when presented with single joints from each time point, the pair having been selected for illustrating repair, even though the images were blinded as to sequence and were randomly ordered and mixed with cases of progression and equivocal or no change when presented to the readers. Furthermore when the panel was shown the entire hand or foot film in a separate session that included the joints selected as demonstrating repair, the panel again selected the second in the true order as improved.
