How long it takes to walk with a fracture in the knee depends on the patient’s treatment, the extent of the fracture, the patient’s age and physical condition, etc. Generally, it takes about 4-6 weeks, but it varies. Patients with fractures in the knee can get out of bed earlier than those with conservative treatment, as the surgical treatment is more firmly fixed, and they can usually put weight on the ground about 4 weeks after surgery. For conservative treatment, most patients are recommended to get out of bed and put weight on their knees in about 6-8 weeks. In addition, in the case of severe comminuted fractures, the period of weight-bearing should be extended to about 8 weeks, and the degree of fracture recovery should be reviewed in a timely manner. The knee fracture must be fixed in time, and rehabilitation should be carried out as early as possible. During the braking period, appropriate massage should be performed to promote blood circulation and prevent the formation of venous thrombosis.
