Artificial hip arthroplasty is an important method of treating advanced femoral head necrosis. If the surgery is successful, the recovery is faster, but after discharge, patients should still pay attention to some details of life. The postoperative care methods of artificial hip replacement are as follows: 1. Sitting The sitting time should not be too long in the first month after surgery to avoid hip edema, and can be improved by applying cold compresses and elevating the affected limb, keeping the knee joint lower than or equal to the hip, not sitting on a chair or sofa that is too low, not crossing the legs and not bending forward more than 90 degrees, leaning the body backward and extending the legs forward when sitting. 2.Toilet Use a raised homemade toilet seat to go to the toilet, or lean back with the assistance of the body, extend the affected leg forward to the toilet, pay attention to keep the knee joint higher than the hip. Do not bend down to pick up things on the floor for 2 weeks after surgery, do not turn around suddenly or reach for objects behind you, and place the rice bowl in front of you when eating. 4.Ride in a car Sit with your hips positioned forward, lean your body backward and stretch your legs forward as much as possible. 5.Shower After the wound has healed, rely on reliable objects for showering, because there is a certain danger of standing in the shower, so you can sit on a high stool, the nozzle is a removable handheld nozzle, and prepare a bath sponge with a long handle so that it can reach the lower limbs and feet. 6.Put on and take off shoes and socks Ask someone to help or use shoe plugs, choose elastic shoes without laces, loose pants, and carry shoes medially for those with lateral incisions after the line and laterally for those with medial incisions before the line. 7.Sports and exercise Physical activities that can be performed after full recovery: walking, gardening, cycling, bowling, table tennis, swimming, dancing, and maintaining proper weight. Avoid activities that produce excessive pressure on the new hip joint and cause wear and tear, such as enthusiastic jumping, fast running, skiing, water skiing, tennis, etc. The above post-operative care methods for artificial hip replacement should be noted by patients and their family members who have undergone replacement surgery. If you can do these things in life, it will help a lot to prolong the life of the prosthesis and delay the arrival of revision surgery.
