2. Fig. 1
Study schema. Rats had a single monoiodoacetic acid (MIA) injection in the right knee and phosphate buffer saline (PBS) in the left knee. The knees were evaluated at 2, 4, 6, 8 and 12 weeks after injection. For the control, the left knee of rats which had a 0.1 mg injection in the right knee, was used.

3. Fig. 2
Representative macroscopic features of the femoral and tibial condyle cartilage. (A) Images without India ink staining. Macroscopic cartilage score introduced in Table I is shown in each image. The tibial image with median value is selected among four samples and the femur is selected from the same knee. In the control group, the images of the left knee were inverted horizontally to match the images in the other groups. (B) Images with India ink staining. Punctate depressions are indicated with white arrowheads. Erosions are surrounded with yellow arrowheads. Areas of bone destruction are surrounded with red arrowheads. A; anterior, P; posterior, M; medial, L; lateral.

5. Fig. 4
Histological analyses for the tibial condyle. (A) Representative histological features of the tibial condyle. Medial tibial condyle was sectioned in the sagittal plane and stained with safranin-o. OARSI histological score and Mankin score are shown in each image. The tibial plateau image with median value is demonstrated. A; anterior, P; posterior, O; OARSI histological score, M; Mankin score. (B) OARSI histological score for tibial cartilage. Values are means with 95% confidence interval (n = 4). (C) Mankin score for tibial cartilage.

6. Fig. 5
Analysis for infrapatellar fat pad (IFP). (A) Study schema. (B) Representative histological images for the IFP. Whole knee joints were sectioned in the sagittal plane stained with hematoxylin and eosin. Infrapatellar fat pad inflammation score (surface score + body score) are shown in each image. (C) Infrapatellar fat pad inflammation score. Values are means with 95% confidence interval (n = 4).

7. Supplementary Fig. 1
Representative histological features of the tibial plateau. Medial tibial plateau was sectioned in the sagittal plane and immunostained with type II collagen.
