After discharge from the hospital, in order to better protect your joints and improve the quality of your life, you need to pay attention to the following matters in your daily life: 1. When standing up or sitting down, first straighten the affected limb (surgical side limb) and support your torso with both upper limbs on the armrests of the chair to stand up or sit down. 2.After arthroplasty, use a high-backed chair with armrests and appropriate height. 3. Avoid flexion of your hip joint beyond 90 degrees. Forbid cross-legged, forbid erlang-legged, forbid sitting on low stools, soft sofa, forbid deep squatting action. 4.Avoid bending and pulling the quilt in bed, squatting to relieve the bowels or using a low toilet and other dangerous movements. 5, within two weeks after hip replacement surgery, you should lie flat, forbid lateral lying, place the affected limb in abducted neutral position, and place pillows between the lower limbs to prevent the affected limb from excessive induction. Four weeks after the operation, lateral lying to the healthy side is allowed, but pillows should be placed between the lower limbs. 6. When picking up things from the ground, excessive bending should be avoided, and a pick-up device can be used. Or use the upper limb to hold on the auxiliary, first flex the hip and knee on the healthy side, then kneel on the ground with the affected knee (hip replacement side) to pick up things. 7. When putting on and taking off shoes, sit on a chair and keep the hip flexed less than 90 degrees, bend the knee of the leg to be taken off and place the foot under the knee of the other leg. Do not wear laced|, because it is easy to make you slip and fall, in addition to the trouble of tying up. 8.When going upstairs, the healthy limb should go up first, and when going downstairs, the affected limb should go down first, for the same reason, you should pay attention to this point when going up slopes, steps and uneven ground. One step at a time is safer than alternating legs, so you better take one step at a time. 9, strengthen muscle strength. Good muscle strength can not only make patients move freely, but also can reduce the force on the joints to a certain extent, so usually insist on exercising the muscle strength of the affected limbs. 10, in standing must ensure that the leg straight, walking to maintain a normal gait walking, can not curl the leg walking. 11.Avoid a lot and high activities.
