Representative sagittal medial meniscal T2* maps and corresponding fused second harmonic generation (SHG) and autofluorescence (AF) multiphoton microscopy (MPM) image data. Tear limbs had focal increases in T2* (arrow) and disrupted collagen fibers in MPM imaging (arrow heads). Non-Op limbs had reduced heterogeneity of T2* and highly ordered collagen structure in the MPM images. Scale bars are given for the T2* maps and MPM images.
