With the increasing awareness of fitness, physical exercise has become a widely accepted important means of preventing and treating diseases, especially chronic diseases, among our people. However, sports trauma often makes many enthusiastic exercisers unable to train normally. There are many reasons for the occurrence of sports trauma, except for some accidental factors, the occurrence of sports trauma is regular, and most of the sports trauma can be expressed by “three more”, that is, “more chronic injuries, more small trauma, more accumulated injuries”. When deciding whether a patient needs surgery or not, the sports trauma surgeon is often judged by whether the injured area affects the motor function. Since the function of the operated limb is definitely affected in the postoperative phase, despite the very good rehabilitation measures, it will still affect the patient’s exercise, and some patients may never even reach the original level of function after surgery. Therefore, even if a sports trauma occurs, as long as it does not affect the exercise capacity, sports medicine doctors advocate the immediate adoption of more radical surgical methods to solve the problem, but try to maintain the patient’s exercise capacity by means of rehabilitation, until the patient must be operated before considering surgery to solve the problem. In this sense, special emphasis should be put on early treatment of sports trauma, so as not to accumulate small trauma into big trauma, and not to drag the sports trauma into a chronic injury. Early treatment, early intervention and early rehabilitation are actually to prevent the occurrence of big traumas and avoid excessive surgical intervention. Of course, even so, there are always many patients who have to accept to receive surgical treatment for various reasons. Although the surgery may be minor and minimally invasive, temporary loss of function can still occur, and this is the problem that must be addressed in the rehabilitation of patients with sports injuries. The best time for rehabilitation interventions in the perioperative period The need for further injections and medication after surgery in patients with sports injuries is rare, and the full restoration of the patient’s motor abilities rises to the top of the list. Rehabilitation not only allows the patient to maintain the best functional status of other parts of the body to the maximum extent possible during the medical intervention, but also allows the limb part that received surgery or other treatment to regain its function as soon as possible and return to its pre-injury functional status, so that it can be quickly put into physical exercise. In fact, sports injuries occur mainly in the extremities, especially in the joints. According to statistics, knee joint injuries account for about 50% of all sports injuries, and other joints such as shoulder, ankle, elbow, hip and wrist joints also have a considerable incidence. The requirements for rehabilitation after injury to these joint parts are very high and require strict training and treatment under the guidance of rehabilitation physicians and rehabilitators. The perioperative period of sports trauma is the best time to cut into rehabilitation. Since most patients are injured when they are young and strong, they are not acclimated both psychologically and physically. During this period, the rehabilitator has to help the patient to adapt to the physical inconvenience after surgery, such as how to walk with crutches, how to take care of their own life, and also how to exercise the function of the uninjured part. For patients with sports injuries, rehabilitation consists of two parts: one is to maintain the optimal function of the whole body, and the other is to gradually restore the function of the injured area. In the functional rehabilitation of the surgical site, it is necessary to proceed gradually according to the medical advice, neither too fast nor left to chance. It is common to see that a patient does not move after surgery due to fear of pain, resulting in loss of function of the affected limb; some patients also move too early after surgery, resulting in the effect of surgery being affected. Three major problems need to be solved in the recovery of sports trauma The rehabilitation of injured parts mainly focuses on the following three problems. Once these three problems are solved, the basic function of the affected limb can meet the requirements of continuing sports. 1.To restore the mobility of the affected limb. Regardless of that part of the injury, whether or not surgery, whether or not external fixation is used after surgery, an important training element into the rehabilitation period is to restore the range of motion. If it is a joint site, it should be restored to the same basic range of motion as the contralateral joint. Bleeding during surgery, postoperative external fixation, and other factors tend to cause joint adhesions. Therefore, the restoration of joint mobility for a period of time after surgery is an important element of rehabilitation. 2. The strength of the periarticular muscles must be restored, because surgery and external fixation itself can lead to disuse atrophy of the periarticular muscles, which has a great impact on postoperative joint function. As the muscle groups around the joint can not only make the joint move normally to meet the needs of limb activities, but also is an important structure to stabilize the joint. If the muscle groups atrophy too much, the joint will not be able to meet the needs of movement either, which can very easily lead to re-injury. Generally speaking, the strength of the muscles around the joint will be gradually strengthened as the rehabilitation process proceeds, and the strength of the corresponding muscle group on the opposite side needs to reach 70% or more before the training can be gradually resumed. 3. The training of proprioception should be strengthened during the rehabilitation process. Because the injury may lead to proprioceptive function loss, and after surgery as a deep feeling and can not quickly return to normal, need to continue to strengthen the training of proprioception in the recovery process, to ensure that later in physical exercise is not due to the loss of proprioception and re-injury. This is especially important in the rehabilitation process of some patients with joint ligament injuries.
