After a sports injury, we usually choose one of two options: conservative or surgical treatment. Regardless of the response, rehabilitation should be introduced at the right time and at the right level during the recovery process to ensure that the many impairments caused by braking are avoided or mitigated as much as possible. Regardless of the treatment option, the initial goal is to reconstruct the anatomical structure, and after surgery/conservative treatment, varying degrees of braking are unavoidable. The main manifestations are adhesions and contractures. Long-term braking makes the relevant joints continue to be in a relatively static state, the muscles, tendons, ligaments, joint capsule, skin and other soft tissues around the joint will produce a significant contracture phenomenon, in the process of joint movement, the soft tissue in the direction of joint movement antagonism will produce a much higher than normal level of resistance, when the resistance exceeds the maximum force of the active muscle that produces the movement, the action can not be completed. At the same time, due to bleeding in the injury, a large number of fibroblasts are released into the interstitial space, thus producing a “glue” effect and forming extensive adhesions in the tissue. In addition, as a result of braking, a large number of transverse bonds are created between the free sliding myofilaments of the myogenic fibers, which prevent them from sliding, thus forming adhesions within the muscle. During the whole braking process, contractures and adhesions occur simultaneously and act together, and a short period of training time will result in serious ROM impairment, sowing the seeds of difficulties for training. 2, injury-related joint cartilage quality decline – joint cartilage nutrition mainly from the joint fluid, in the normal movement, the cartilage surface between the mutual sliding, extrusion will make the cartilage like a sponge absorbing water in its internal and external environment to form material exchange, so as to achieve its nutritional process, long braking seriously impede the metabolic function of cartilage In the future, the normal activities will accelerate the rate of degenerative osteoarthritis and aggravate its severity. 3, affect the healing of damaged tissue – not conducive to tissue repair. Whether it is bone tissue or other soft tissue, its healing cannot be separated from the appropriate stress. Take the joint ligament as an example: the healing of the ligament (external fixation conservative treatment or surgical reconstruction) will appear 2 weeks after the disposal of obvious collagen fiber connection, about 6 weeks fiber connection has been more reliable, but at this time the fiber arrangement order is disordered, the strength is only close to the normal ligament stress level of about half, can not reach the normal function of the treatment is declared failure. 4, the overall functional level of the whole body decreases – because the absolute brake can cause different degrees of respiratory system (lung capacity decline, pulmonary embolism, etc.), circulatory system (circulating blood volume reduction, thrombosis, etc.), digestive system (loss of appetite, etc.) and other system functional degeneration, at the same time, in addition to the injury-related parts, the motor system will also have the overall functional Level of decline, such a comprehensive systemic degeneration, for frail and elderly people especially has a horrible killing power. 5, heart factors – long-term social isolation on the patient’s psyche caused by the huge pressure is not negligible aspects. 6.Economic factors – the consequences of being cut off from economic resources in this era are very serious. In a word, after sports trauma, long-term braking will have a huge impact on the patient, and even excessive local braking may cause serious consequences, so the patient should be rehabilitated in a scientific way, at the right time and in the right degree for the patient’s injury, and strive for the patient to be injured but not disabled, and return to society as soon as possible.
