The ICRS (International Cartilage Repair Society) score for quantitative macroscopic evaluations. There were no statistically significant differences in the scores of G-I, II, and III at 2 weeks. At 4 weeks, the scores of G-II and III with DN gel were significantly higher than the untreated controls in all groups (p < 0.0001). The scores in the G-I untreated controls were significantly higher than those in the G-II and III untreated controls (p < 0.0001). At 12 weeks, there were no significant differences between the DN gel and untreated controls in any group. There was a significant difference in the score between the G-I with DN gel and G-III with DN gel, and between G-II with DN gel and G-III with DN gel (p = 0.0010, p = 0.0331, respectively). And the scores in the G-I untreated controls were significantly higher than those in the G-III untreated controls (p = 0.0004)
