After tendon repair surgery. The flexor tendon, in particular, may be severely tendon adhesions child require second stage release surgery. In fact, most tendon repairs do not require re-release surgery if handled properly. The causes of tendon adhesions are analyzed as follows: The degree of adhesions and suture technique are related to each other, generally the suture is advocated to be flat at the severed end and the suture strength is high, currently the better suture is Tsai type six-strand suture, the higher the suture strength, the better the early postoperative exercise. Tendon adhesion is an inevitable process in the tendon healing process, but the more serious the local injury is, the more obvious the scar adhesion is. So the recovery effect after crush injury are not as good as cutting injury. The results vary depending on the location of the injury. The proximal and middle finger tendons are in a very narrow canal and have the highest rate of postoperative adhesions. Postoperative functional rehabilitation is the most neglected, and patients often believe that the surgeon should be solely responsible for the outcome of their treatment. In fact, 70% of the treatment should take place in the rehabilitation unit. Rehabilitation interventions should be done early after surgery, with the attending surgeon and a professional rehabilitation physician working together to develop a complete functional rehabilitation program.
