Almost every patient with an osteoarticular trauma has two questions, “When will I be able to return to sports? What is the process of rehabilitation like?” I have summarized a simple and most important principle: step by step and follow the feeling. To explain it simply, the patient needs to carefully experience the state of his or her body, especially the injured part (the next paragraph explains this state), and gradually resume rehabilitative exercises. form and degree of exercise is tolerated. In other words, everyone has a sense of his or her own tissues, and whether it is at the time of injury or during the rehabilitation process after injury, the patient will feel the state of his or her injured tissues more accurately; after this feeling is analyzed by experienced doctors and then informed to the patient, most patients can grasp their injury and recovery state more accurately; this feeling is often more accurate than the doctor’s experience, and has a more precise meaning for the guidance of rehabilitation. This feeling is often more accurate than the doctor’s experience and has a more refined meaning for the guidance of rehabilitation. In fact, each person is indeed one of his or her own best doctors. Because doctors cannot personally experience what patients feel, and because doctors have not had every disease, most of their knowledge comes from patients’ complaints and the experience left by their predecessors, only the patients themselves can personally experience the pain of the disease. Therefore, it is only necessary to have a certain amount of general medical knowledge (which requires patient teaching from professional doctors and learning from other sources), and under the guidance of other professional doctors, patients can usually help you to make a smooth recovery on their own. However, we must not go to the other extreme of following our feelings completely and not listening to the advice of our doctors. Because patients have limited medical knowledge after all, they sometimes make wrong judgments. This is the time when a professional doctor is needed to help guide and gatekeep the rehabilitation results.
