The bandage is too tight after ACL reconstruction surgery can be loosened appropriately under the doctor’s guidance, but not too loose. 1. The bandage is tied tightly after ACL reconstruction surgery in order to play a good role in fixing and stabilizing the knee joint and to a certain extent to the surgical wound compression and hemostasis, so it is not recommended to adjust the tightness of the bandage within the tolerance range. 2. But if the patient feels that the bandage is too tight, whether it affects the blood circulation of the patient’s lower limbs. It is recommended to check whether the distal limb of the bandage has low skin temperature and purple skin, etc. If the bandage is too tight to affect the blood circulation of the distal limb, it is recommended to loosen the bandage and rewrap the bandage immediately, such as the skin temperature and the color is normal, depending on the patient’s tolerance level to decide whether the bandage needs to be loosened. 3. At present, many hospitals use elastic bandage after ACL reconstruction surgery, and it is almost impossible for the bandage to be too tight after surgery. It is not recommended to adjust the tightness of the bandage by yourself, and it is recommended to adjust the bandage under the guidance of the doctor.
