ETHODS: The gastrocnemius bundle branch and soleus muscle bundle branch of the right achilles tendon were sutured after surface skin and subcutaneous tissue discission. The gastrocnemius bundle branch was transected at 2 cm above calcaneal bone insertion and a 2-cm silicone tube was applied to separate the site of suture using 5-0 modified Kessler method. The site of suture was treated with nothing in silicone tube as the blank control group. In other three groups, the site of suture was treated with 100, 50, 10 ng VEGF in silicone tube at the operation day and 7, 14, 21 days post-operation.
