Histology and OARSI score

Rabbits were euthanized [25] and the medial condyles of the femurs were fixed with 4% paraformaldehyde (Boster, Wuhan, China) overnight at 4°C on a shaker. Whole medial condyles were decalcified in 14% ethylenediaminetetraacetic acid for 5 days at 4°C on a shaker. After dehydration by gradient alcohol and infiltration by xylene and paraffin, cartilage samples were embedded in paraffin. Paraffin-embedded joints (4 μm) were sectioned on a sagittal plane. Samples were stained with safranin O (Hengyuan,Shanghai, China) and fast green (Hengyuan) using standard protocols. All sections were evaluated for histologic signs of cartilage degeneration using a modified Osteoarthritis Research Society International (OARSI) scoring system [26].
