Biomechanical analysis and ultrastructure of repaired patellar tendons at 4 weeks after surgery. Biomechanical analysis for maximum load (a), stiffness (b), maximum stress (c), cross-sectional area (d), and elastic modulus (e) in the hypoxia and scramble group and the hypoxia and shRNA group. Representative images of transmission electron microscopy of the hypoxia and shRNA group (f) and the hypoxia and scramble group (g). Scale bar = 200 nm; magnification, × 15,000. h The distribution of collagen fibril diameters of the hypoxia and shRNA group and the hypoxia and scramble group. i The average diameter of collagen fibrils of the hypoxia and shRNA group and the hypoxia and scramble group. Data were shown as mean ± SD. ★p < 0.05; ★★p < 0.01
