If the patient had followed the correct instructions of the surgeon and the rehabilitation doctor, the problem you describe would not have occurred. There are several reasons for this: one is that the doctor’s instructions were late; another is that the patient himself did not pay enough attention to the exercise, which delayed the time. However, it is important to stress that it is never too late to mend the fold, and overcoming problems as early as possible can be useful. But there is one thing, if you don’t exercise for a week or two weeks, you may be able to make up for it, but if you wait until three or four months later, it will be very, very difficult to recover. At this point, the patient may not be able to move the joint at all through the patient’s own active exercise, and the surgeon will need to perform a new joint release surgery to achieve the function of the joint. For example, we rarely see stiff joints in patients with fractures in the United States, but the incidence of postoperative bone discontinuity is much higher in the United States than in China. What is the reason for this? The different level of importance and understanding of rehabilitation. There must be a goal to reach when moving around. The first problem is normal walking, which is the most basic; then climbing hills and stairs, one of the most important requirements to achieve this function is that the patient can dorsiflex 20-30 degrees of the ankle joint; the third function is squatting, in the past, when there was no toilet, the toilet was squatting, squatting requires our The third function is squatting. Therefore, one of the most important goals for patients after ankle surgery is that the dorsiflexion of the ankle joint must reach the same degree as the normal limb on the other side, and the dorsiflexion of the ankle joint and the plantarflexion of the ankle joint must reach the same goal.
