The SF-Lipo@KGN scaffold promotes cartilage defect repair and ECM deposition. (A, B) Macroscopic, hematoxylin and eosin (H&E) staining, and safranin O (S.O.) staining representative pictures of cartilage defects at 6 and 12 weeks after the operation. Scale bar = 800 μm and 100 μm. (C, D) ICRS macroscopic score and MODS histological score were used to evaluate the degree of cartilage repair. The data are presented as mean ± SD (n = 6). *Indicates statistically significant differences where P < 0.05, ** where P < 0.01 between the indicated groups; #where P < 0.05, ##where P < 0.01 versus the sham group.
