Knee fracture patients should pay attention to the treatment prescribed by the doctor, strengthen life care, and also regularly consult the doctor for review. 1. Compliance with medical treatment: In the acute stage of knee fracture, patients should pay attention to properly fix the injured part to prevent aggravation of the condition. Patients with open fracture should cooperate with the doctor for thorough debridement and treatment, and also choose manipulation, bone traction, skin traction and other treatments according to their own conditions. For severe pain, diclofenac sodium, celecoxib, tramadol and other drugs can be used as prescribed by the doctor. In addition to the above treatments, serious knee fractures need to be treated with surgical procedures such as cut-and-replace internal fixation, amputation, bone grafting, external fixation and other surgical treatments. After the operation, if the condition permits, actively cooperate with the doctor to carry out ankle pump exercise or get out of bed appropriately to prevent local muscle atrophy. 2. Strengthen life care: knee fracture patients should eat more nutritious food, such as milk, soy milk, lean meat, fish and shrimp, etc., in order to replenish the calcium and other nutrients needed by the body, which is beneficial to the promotion of bone recovery. Family members should pay attention to maintaining the cleanliness and hygiene of the fixed parts of the patient, and should also be diligent in turning over and buckling the back to prevent the occurrence of complications such as pressure sores and crashing pneumonia. In addition to the above points of attention, knee fracture patients should also follow the doctor’s instructions to regular medical review, in order to monitor the body’s recovery and timely treatment of abnormalities. It is recommended that patients follow the doctor’s instructions, and not to use drugs or prescriptions indiscriminately.
