Representative histology images of femoral articular cartilage. A–D surgically induced group. E–H chemically induced group. Safranin O/fast green stained with 20× magnification. At week 4, the surgically induced group showed apoptosis indicated by empty chondrons (red arrow) and superficial fibrillation at week 8 (asterisk). Uneven cartilage surface can be seen at week 4 in the chemically induced group (asterisk) and cartilage erosion at week 12
