Normal gait can usually be resumed in 3 to 6 months after knee replacement if there are no complications and recovery is good. Under the modern concept of accelerated rehabilitation surgery, one day after knee replacement, you can walk on the ground. Early walking on the ground can exercise the muscles of the lower limbs and prevent complications such as deep vein thrombosis of the lower limbs, but due to the traumatic stress of the surgery and the destruction of the muscles around the knee, it is difficult to achieve a normal gait at an early stage of walking. About 1 month after knee replacement surgery, the surgical incision is healed, and the main focus is on weight-bearing walking and exercising the muscle strength around the knee joint, and regular and timed exercise of muscle strength and knee joint mobility, which can make the knee joint function more satisfactory. Three to six months after knee replacement, after the preliminary exercise, the strength of the muscles around the knee joint and the mobility of the knee joint can basically reach satisfaction, and if the recovery condition is good, normal walking can be resumed completely. After knee replacement surgery, you should have regular checkups and follow the doctor’s instructions to carry out activities and functional exercises, do not blindly exercise on your own, so as not to delay the condition.
