Appearance of knee joint specimens. (A) Representative images of general appearance of each group at 4, 6 and 8 WPI. (B) Quantitative analyses of ICRS scores of each group at 4, 6 and 8 WPI. n = 3. Rats in Group A received minced cartilage (mixed with fibrin glue) transplantation, rats in Group B were treated with chunk cartilage (mixed with fibrin glue) implantation, and cartilage lesions of Group C were only filled with fibrin glue. *P < 0.05, Group A versus Group B. #P < 0.05, Group B versus Group C. Data are mean ± SD. Two-way ANOVA with Turkey post-hoc test was used to perform multiple-group comparisons. Scale bar = 1 mm.
