In clinical practice, surgical treatment with tendon anastomosis can only be performed after a complete rupture of the tendon has occurred. In clinical practice, surgical anastomosis is mainly performed on the tendon of the heel, that is, after a rupture of the Achilles tendon has occurred. There are several clinical approaches: the first is the braiding method, which involves braiding the two heads of the ruptured tendon together like a braid. The advantage of this procedure is that after surgery, the strength of the tendon rupture is well anastomosed and strong, and secondary ruptures do not occur easily. However, there are also disadvantages. The disadvantage is that due to the overly intensive braiding, the toughness of the tendon disappears and the tendon toughness is more damaged. The next is the ring-tie anastomosis method. The advantage of this method is that after passing the ring-tie, the toughness of the tendon is well protected and there is little damage to the tendon. The disadvantage is that after the anastomosis, the tendon strength is not strong enough, and it is easy to occur the second is rupture. Therefore, after the tendon anastomosis, all should be given local brake. Before activity, be sure to perform functional exercises under the guidance of a doctor.
