Follow-up evaluation of articular cartilage regeneration
| Presence of newly formed cartilagenous tissue, n (%) | Group A (n = 24) | Group B (n = 25) | Group C (n = 25) |

The grade of articular cartilage regeneration was compared by Pearson’s chi-squared test
MFC—medial femoral condyle; MTC—medial tibial condyle
*Significant difference compared with the placebo controls (Group C)
