Many patients undergo surface surgery of the artificial knee for reasons such as advanced osteoarthritis of the knee or advanced rheumatoid arthritis. Patients quickly return to normal ambulation and improved quality of life under the proper guidance of their physicians. It takes the combined efforts of the patient and physician to achieve a satisfactory level of recovery. Today we will talk about how to quickly recover a healthy gait after receiving an artificial knee replacement. 1. Be prepared psychologically and be confident. Because of the surgical trauma and knee proprioceptive factors in the early postoperative period, patients may be fearful, worried about not being able to walk well, and have no confidence in postoperative functional recovery. Therefore, patients must have good self-confidence and need encouragement from the doctor. 2, because the knee function is mainly reflected in the joint mobility and quadriceps, N rope muscle strength, so the main content of postoperative rehabilitation is joint mobility exercise and quadriceps, N rope muscle strength exercise. The exercise program must follow the doctor’s arrangement, do not add or change without permission. 3. The affected limb needs to be placed in the correct position after surgery. After total knee replacement surgery, the affected limb must be placed in a straight position, with the heel of the affected side padded and the knee underneath suspended, not padded, to avoid flexion contracture deformity of the knee in the future. 4. In the early post-operative period, ice should be applied to the front of the affected knee every two hours for 15-20 minutes each time, and the ice should be applied for 3 hours after one month, which should last for three months. 5, the second day after surgery, the patient needs to support the walker every day, full weight-bearing high leg walking, walking every 2-3 hours, 10-15 minutes each time, generally a week after surgery can go to the crutches full weight-bearing walking. Finally, the exercise of the ipsilateral hip joint should not be neglected. The function of the hip joint should also affect the exercise of knee mobility, and the hip joint should be placed in the corresponding position during the exercise of knee mobility. Therefore, when exercising the knee mobility, the hip function should be exercised at the same time.
