A Schematic diagrams of lap shear testing on the meniscus slice B Load-displacement curves and lap shear strength of S-Gel with the different concentrations of PIL bonding with meniscus slice. Data are presented as mean ± SD (n = 3 independent experiments), and exact p-value was calculated with one-way ANOVA Tukey’s multiple comparison test. C Swelling conditions and D swelling ratio of S-Gel and S-PIL10 in PBS buffer. Data are presented as mean ± SD (n = 3 independent samples). E Ashby plot of S-PIL10 compared with reported adhesives. F Macrograph and stress-strain curves of S-PIL10 with cyclic compressive loading-unloading testing for 1000 cycles. G Twisting and water-flushing after meniscus adhesion by S-PIL10. H Load-displacement curves of S-PIL gel bonding meniscus tear and SEM image of interface between S-PIL10 and meniscus. I Retention condition of S-PIL bonding meniscus tear after 60 days.
