After hip replacement surgery, it is important to perform appropriate functional walking exercises every day, and the exact distance varies for each individual. Hip arthroplasty is the replacement of diseased tissue with an artificial hip joint, which improves the ability to walk. It is important for elderly patients to prevent complications associated with prolonged bed rest. In the early days after hip replacement (within 3 days), you can walk on the ground. In the early days, the main purpose is to adapt, and it is best to control the walking distance within your own control. As you continue to adapt and heal, the walking distance and function will continue to improve. In about 2~3 months after the operation, basically it can meet the function of daily life.
