Quantitative Analysis of Contrast-Enhanced Ultrasound That Can Be Used to Evaluate Angiogenesis during Patellar Tendon Healing in Rats

Figure 1

B-mode ultrasound imaging of the patellar tendons in the control and operation groups. (a) The structures of I control group, II 7 days, III 14 days, and IV 28 days after surgery are shown clearly. The triangles point out the maximum thickness of the patellar tendons. The arrows point to strong echoes from suture lines. (b) All of the tendons thickened after surgery. Data are expressed as the mean ± SD (n = 10 rats at each time point). p < 0.01; p < 0.001.
