How long it takes to walk after conservative treatment of patellar fracture depends on the severity of the patellar fracture, the degree of healing and your own condition. The time to walk varies from case to case. For mild cases, it usually takes 4 to 6 weeks to walk on the ground, while for severe cases, it may take 2 to 3 months to walk on the ground. In mild patellar fracture, under the condition of keeping the knee in the straight position, plaster cast or lower limb support immobilization treatment is usually carried out, and the immobilization device can be removed after 4 to 6 weeks, and the training of walking on the ground can be started. In severe patellofemoral fracture or patellofemoral fracture in combination with infection, malnutrition, anemia, etc., the fracture healing is relatively slower, and the time of walking down to the ground will be delayed, and it may take 2~3 months to review the fracture healing well before walking down to the ground. Therefore, patellofemoral fracture should go to the hospital in time, according to the doctor’s guidance for standardized treatment and functional training, do not move too early on your own, so as not to cause adverse consequences.
