(1) Elements Confidence: Rehabilitation exercise is hard, especially at the beginning, you must have confidence in yourself. Persistence: Rehabilitation exercise is not a temporary activity for patients after artificial joint replacement surgery, but needs to be persisted for a long time. Be careful: Safety is very important. A fall can sometimes have very serious consequences and undo all previous efforts. Therefore care needs to be taken when performing any rehabilitation exercises. Early morning rises after surgery require particular attention and must be completed with someone accompanying you. (2) Precautions Use your artificial joint correctly and appropriately so that it can serve you better and for a longer period of time. The following actions should be avoided as much as possible, otherwise the chance of loosening of your artificial hip joint will be greatly increased. ◆ Prohibit “stilted legs” in the morning after the operation, and do not apply pressure while stilting legs; ◆ Prohibit sitting on low stools (about 20cm), including squatting; ◆ Prohibit jumping from high places; ◆ Avoid strenuous exercise; ◆ Avoid falling; ◆ Do not rotate your hip outward no matter lying down or walking; ◆ Do not lie down to the surgical side when lying on the lateral side. Do not lie on your side when you are lying on your side. Rehabilitation exercise for artificial hip joint replacement Perioperative rehabilitation exercise: It is mainly the rehabilitation treatment during the postoperative hospitalization, and it can be divided into several stages according to the postoperative physical recovery. 1.1-3 days after surgery On the first day after surgery, the patient is usually weaker due to blood loss during surgery, the pain of the wound is more obvious, the gastrointestinal function caused by anesthesia has not yet recovered, so he can not eat, and at the same time, the accumulated blood in the joints still needs to be drained out through the retained drainage tube. Therefore, the rehabilitation training at this time is aimed at restoring muscle strength and promoting blood circulation in the lower limbs to prevent thrombosis. Temporary inactivity of the hip joint, because the contraction of the muscles of the lower limbs is like a pump that constantly squeezes the blood back to the heart, the complete lack of activity of the affected limbs after the operation may cause blood stasis and swelling in the lower limbs, resulting in deep vein thrombosis, if the thrombus falls off, it may cause life-threatening pulmonary and cerebral radiculopathy, and meanwhile, complete inactivity of the lower limbs may cause the muscles and joints to lose their elasticity, which will affect the recovery of the limbs and joints function after the operation. Therefore, the lower limbs should be slightly elevated on the 1st-3rd day after surgery to promote blood return to the lower limbs. (1) Flexion and extension of the ankle joint: slowly hook the toes upward and then extend them farther so that the surface of the foot is taut. Do this 5-10 times at 1 hour intervals for 3 seconds each, starting immediately after surgery until you are fully recovered. (2) Rotate the ankle: Rotate your ankle joint from the inside out, 3-4 times a day, 5 repetitions each time. (3) Exercises for the healthy side: contract the muscles of the healthy side of the lower limb by flexing the hip and knee, 1 set of 30 repetitions every 2 hours, each lasting 10-15 seconds. Through this stage of exercise, the following should be achieved: ◆ Basic elimination of swelling of the affected limb; ◆ The thigh and calf muscles on the affected side can coordinate and exert force to make muscle contraction and relaxation movements. 2.Postoperative days 4-7 During this period, the patient can have a normal diet, physical strength gradually recovered, wound pain reduced, blood and fluid accumulated in the joints have been drained out, drainage tubes have been removed, swelling of the affected limb has gradually subsided, and you can start to perform some prone hip activities to restore muscle strength and gradually increase the mobility of the hip joints. 3-4 times a day, repeat the following three exercises 10 times each time: (1) Flexion of the hip, knee joint contact: as shown in the figure, the patient can be autonomous hip, knee flexion and extension, so that your heel slides to the buttocks, and then straighten, be careful not to make the knee swing to the sides. (2) Hip contraction exercises: Hold your hip muscles tight for 5 seconds in the flat position. (3) Abduction contact: straighten the legs in a flat lying position to separate them as far as possible to the sides, then recover them, taking care not to bring them completely together. (4) Quadriceps Contraction Exercise: Keep your front thigh muscles tense by pressing down and straightening the knee as much as possible, hold for 10-15 seconds, and practice 10 times every 10 minutes until you feel a little fatigue in your thigh muscles. (5) Straight leg raising exercise: your thigh muscles in front of you are tense, try to straighten the knee joint, raise the lower limb (10cm from the bed), hold for 5-10 seconds, slowly put it down, repeat the exercise, you will feel a little fatigue of the thigh muscles. (6) Hip straightening exercise: the hip joint of the operative side is actively straightened or the pillow is placed under the hip, which can stretch the hip flexor and the anterior part of the joint capsule. 3.Postoperative day 8-14 According to the recovery situation, continue the previous stage of practice, and can further increase the sitting and standing position of the exercise, to restore the normal hip joint activities while increasing muscle strength. In most patients, the artificial hip joint can be partially weight-bearing at this period (patients with non-cemented prosthesis should delay weight-bearing time, please follow your doctor’s instruction), carry out the following rehabilitation exercises: (1) How to get down to the ground Place the walker beside the operated leg and move your body to the bedside. Move the operative leg under the bed to prevent external rotation of the operative hip. Move the healthy leg under the bed, turn the body upright and stand with the walker. (2) How to sit down Prepare yourself before sitting down. You need a chair with a backrest and armrests, with a cushion, slowly back up, watch your position, hold your hands steady, and then sit down slowly. Hip flexion should not exceed 90 degrees, and sit on a higher chair. (3) Standing Exercises You may feel dizzy at the beginning, so be sure to have someone beside you to assist you and know that you are strong enough to stand on your own. When practicing standing exercises, you must hold on to the side of the bed or the handrail on the wall, and practice 3-4 times a day. Standing Leg Raise Exercise: Hold the handrail with both hands and raise your leg on the affected side, be careful not to raise your knee above your waist, practice 2-3 times each time. Standing backward extension and abduction exercises: slowly backward extension of the affected limb, head up and chest, stretching the hip joint capsule and hip flexor muscle groups, pay attention to keep the upper body upright, 2-3 times each time, and then the lower limb straight outward lifting slowly recycling, stretching the hip joint adductor muscles, 2-3 times each time. (4) How to walk with a walker First, use the walker to assist in walking, keep the center stable, and switch to bilateral axillary canes. Position the walker 20 centimeters in front of the body first, step the art side leg first, then the healthy side leg to follow, and so on. At first, walk for 5-10 minutes 3-4 times a day, and then increase to 20-30 minutes 2-3 times a day after gradual adaptation. After full recovery, you should keep walking for 20-30 minutes 3-4 times a day. Walking helps you maintain muscle strength around the hip joint. Through this phase of exercise you should achieve: ◆ 90 degrees of active hip flexion ◆ Partial weight-bearing walking on your own with the help of a walker ◆ Extended weight-bearing walking with a non-cemented prosthesis
