Fig. 8.

The type 2 collagen immunohistochemical findings of meniscal repair showing the general, repaired area and interface. A: Immunohistochemical evaluations at 8 weeks postoperatively; B: Immunohistochemical evaluations at 16 weeks postoperatively; C: Semiquantitative evaluation of type 2 collagen content reflected by immunohistochemical staining intensity. AOD values are expressed as median values with 95% CIs. n ​= ​6 (except for n ​= ​5 in blank-16W group). ∗, P ​< ​0.05; ∗∗, P ​< ​0.01; ∗∗∗, P ​< ​0.0005. The scale bar of general picture is 2.5 ​mm; The scale bar of repaired area and interface picture is 100 ​μm.

AOD: average optical density, CI: confidence interval
