Figure 5

Average difference in morphological parameters between induced lesions (sutured/non-sutured) and contralateral control meniscal sections. Vascularity, cell density, proteoglycan content (safranin-O), and type I collagen were binned according to the healing status (non-healed, partially healed, and healed tears). The average difference between non-healed (n = 1), partially healed (n = 4), and healed (n = 3) tears and their respective contralateral control are shown with standard deviation bars. Cell density was the difference in cells per mm². All other parameters are differences in percent stain/immunostain positivity. Non-healed tear does not have error bars as there was only one tear with this status. Note the dotted black line indicating no difference between induced lesions and their contralateral control.
