Follow-up evaluation of ICRS grade in articular cartilage
| ICRS grade, n (%) | Group A (n = 24) | Group B (n = 25) | Group C (n = 25) |
|---|---|---|---|
| MFC | |||
| 1 | 4 (17)* | 0 (0) | 0 (0) |

| 2 | 11 (46)* | 8 (32) | 7 (28) |
| 3 | 9 (37)* | 13 (52) | 15 (60) |

The ICRS grade was compared by Pearson’s chi-squared test
ICRS—International Cartilage Repair Society grade; MFC—medial femoral condyle; MTC—medial tibial condyle
*Significant difference compared with the placebo controls (Group C)
