The time to walk normally after knee surgery needs to be determined by the specific surgery method, as follows: First, artificial joint replacement surgery: If the artificial joint replacement surgery is used for severe osteoarthritis, the patient can walk on crutches the day after surgery and gradually resume normal walking, which usually takes 2-3 weeks to recover. Second, knee meniscus suture surgery: If the knee meniscus suture surgery is performed, it usually takes 6-8 weeks before the patient can walk normally. Third, arthroscopic meniscus revision: If an arthroscopic meniscus revision is performed, you can usually walk normally in about a week. Therefore, the normal walking time after knee surgery needs to be determined by the condition and the type of surgery. If walking is done too early, certain structures may not heal completely, making clinical symptoms worse. If joint replacement surgery is performed, early activity is beneficial to the patient’s recovery.
