A: safranin O-fast green staining of the knee cartilage (× 200); A1: CON group; A2: KOA group; A3: Acu group; B: Col-Ⅱ immunofluorescence staining in knee cartilage (× 200); B1-B3: CON group; B4-B6: KOA group; B7-B9: Acu group; C: analysis of the Mankin score; D: analysis of the Col-Ⅱ fluorescence intensity. CON group: no modelling or no intervention; KOA group: 6 weeks of modeling followed by no intervention; Acu group: 6 weeks of modeling followed by acupotomy intervention for 4 weeks. Col-Ⅱ: type Ⅱ collagen; CON: control; KOA: knee osteoarthritis; Acu: acupotomy. The data were presented as the mean ± standard deviation (n = 6). Compared with the CON group, aP < 0.01; compared with the KOA group, bP < 0.01.
