1, although modern artificial joints are more wear-resistant and durable, the materials in artificial joints still have wear and tear problems, so after surgery, you should try to wear low-heeled soft-soled shoes, appropriate walks, outings and indoor work, rather than too much climbing, up and down stairs, running and other strenuous sports, it is best to use sports that rarely increase the load on the joint, such as swimming, in situ cycling, etc., so as to prolong the service life of the artificial hip joint 2. Avoid cross-leggedness between the affected limb and the healthy limb in any position (cross-leggedness, cross-leggedness, etc.) and avoid flexion of the affected hip over 90°. Avoid the affected hip to be in internal retraction, internal rotation and semi-flexion position. Avoid the action of standing up from a sitting position when the hip is in internal retraction and internal rotation; 3. Lie on your back as much as possible within 3 months after surgery, if you need to lie on your side, turn over to the affected side or lie on your side: straighten the affected hip joint to maintain the neutral position of the affected limb, and pad soft pillows in front of and behind your chest; turn over to the healthy side or lie on your side: slightly bend the healthy limb under, straighten the affected hip joint when turning over, and pad a larger soft pillow between the two legs on your side to separate both knees and both feet, so that both feet Avoid sitting in a chair that is too short (knee is higher than hip when sitting), and add a cushion if necessary to keep the hip joint flexion less than 90°. When sitting, do not lean forward more than 90°, when standing up, gradually slide the hip to the edge of the chair, and then stand up with crutches or other supports; 5, pay attention to reasonable nutrition but need to control weight, quit smoking and alcohol, prevent infection in various parts of the body (lung, urinary system, oral or other infections), once the wound redness, swelling, yellow sputum, body temperature over 38 ℃ and other signs of infection, need to immediately seek medical attention; 6, postoperative Method of getting out of bed within 3 months: the patient first moves to the bedside of the healthy side, the healthy side leg first leaves the bed and makes the foot on the ground, the affected limb abducts, flexes the hip <45°, and is assisted by others to lift the upper body so that the affected leg leaves the bed and makes the foot on the ground, and then stands up with double canes; when getting into bed, proceed in the opposite direction, that is, the affected limb gets into bed first, and the patient gets into bed by himself using the support of both upper limbs and the healthy side lower limbs. 3 months after surgery, self-help method of getting out of bed: the foot surface of the healthy limb placed after the ankle joint of the affected limb (the toe of the affected limb is kept facing upward), hands on the bed, with the hip as the axis, rotate and move the body to sit on the edge of the bed, you can get out of bed with crutches; 7, walking with crutches or walkers until no pain, no limp can be considered to abandon crutches, crutches as far as possible when accompanied; abandon crutches when going out as far as possible to use a cane, this practice has two main benefits: first, can This practice has two main advantages: first, self-protection, second, can also be a hint to the surrounding crowd, indicating that the patient's mobility is limited, to prevent crowding, impact, accidents. Do not walk on smooth, uneven surfaces. Keep the road ahead clear within the patient's range of motion to avoid the affected limb encountering unnecessary collisions or large crossing movements. Commonly used items should be placed in an easy-to-reach place to prevent squatting or tiptoeing when picking up items; 8. Avoid excessive bending because bending at the same time as flexing the hips creates a squatting motion, which is very dangerous. Don't turn around suddenly or reach for the objects behind you, and turn around with the whole body turning, not only the upper body. Do not bend down to pick up things on the ground within one month after surgery, ask others to do it for you; 9. In the early postoperative period, family members should help to put on and take off pants and shoes, and try to wear loose pants and shoes. When putting on pants, put on the affected side first and then the healthy side (the opposite when taking off). Avoid bending movements when putting on shoes and socks, sit on a stool, extend the hip and slightly abduct the external rotation, bend the knee, pick up the shoe with the toe, lift the shoe from the inside with a long-handled shoe paddle, and put on the socks with the help of a long-handled clip; 10, use a higher toilet seat to go to the toilet, or lean the affected limb forward to go to the toilet with assistance, squatting toilet is strictly prohibited; 11, any abnormalities of the hip joint on the operated side, such as: abnormal pain, shortened limb deformity, etc. Any uncertainty in working life should be consulted for medical attention. There are many details that need to be paid attention to in life, and the above list is inevitably missing. Patients and their families need to think more and pay more attention according to the relevant principles, and gradually get used to the post-operative lifestyle.
