Meniscus injury patients are recommended to take the supine sleeping position, and when sleeping, it is recommended to the back side of the knee joint, that is, the popliteal fossa, pad small pillows, so that the knee joint to maintain a semi-flexed position, which will minimize the pressure borne by the meniscus, at this time the meniscus can be given to play a maximum help in the recovery of the meniscus. Patients with meniscus injuries are advised to try not to take the side-lying position or the prone position. In these two positions, it will cause a certain amount of extrusion on the meniscus. If the patient has unconscious knee movements during sleep, then it may cause the meniscus to be sheared, at which point it may aggravate the meniscus injury. However, in clinical practice, if the meniscus damage is more serious, the doctor will usually use an adjustable knee brace to immobilize the patient’s knee and the whole lower limb. It does not matter what position the patient sleeps in, but if no such immobilization is used, it is recommended that the patient sleeps in the supine position to allow the meniscus to achieve the best possible recovery conditions.
