Meniscus injury at home rest does not necessarily have to lie down. 1. After meniscus injury, patients should take braking rest, avoid sports and so on, so as not to cause secondary injury. Patients can elevate the affected limb to avoid excessive sagging, so as not to cause congestion and edema. According to the severity of the disease, patients can sit or lie down to carry out functional exercise of isometric contraction of the lower limb muscles, in order to avoid muscle atrophy of the lower limb, poor blood flow, and also to prevent thrombosis of the lower limb. 2. Patients who have recovered well through review can carry out light activities appropriately, but avoid excessive flexion and extension. Patients should carry out rehabilitation exercises according to their own conditions and under the guidance of doctors. If the meniscus is injured, it is recommended to go to the hospital in time, under the guidance of the doctor for regular treatment. For patients with braking, they should also carry out rehabilitation training under the guidance of doctors to avoid complications.
