Analyses of macroscopic observations for the medial tibial cartilage. a Macroscopic features stained with India ink. Cartilage erosion is indicated with arrow. Osteophyte is indicated with arrowhead. b Method for measurement of India ink positive area of the medial tibial plateau. A boxed area to measure India ink positive area was fixed, the fixed area was gray-scaled, the threshold for India ink positive area was decided, and India ink positive area was quantified. c Quantification of India ink positive area (n = 5, *p < 0.05, **p < 0.01 by Paired t-test). d Gross finding score (n = 5, *p < 0.05, **p < 0.01 by Paired t-test). e Osteophyte score (n = 5)
