2. Fig. 1
Human cartilage samples excised from the posterior condyle of the femur. The cartilage samples were graded macroscopically using the Outerbridge classification as grade 1 (A), grade 2 (B), grade 3 (C), grade 4 (D). Open circles (4mm in diameter) indicate the measurement area of macroscopic, spectrocolorimetoric and histological assessment.

3. Fig. 2
Box and whisker plots of the L*, a*, b* values (A – C) and the Y/R SRP values (D). The Y/R SRP was calculated using the following equation: Y/R SRP=Spectral reflectance ratio at a wavelength of 580nm (yellow as the cartilage color)/Spectral reflectance ratio at a wavelength of 680nm (red as the erosive bone color)×100. Each box represents the 25th and 75th percentiles. Lines inside the boxes represent the median. The vertical bars indicate the range.

Scatter plot of the L*, a*, b* values (A – C) and the Y/R SRP values (D). The Y/R SRP was calculated using the following equation: Y/R SRP=Spectral reflectance ratio at a wavelength of 580nm (yellow as the cartilage color)/Spectral reflectance ratio at a wavelength of 680nm (red as the erosive bone color)×100.
