Hello everyone, with the soaring economy and the progress of science and technology, artificial joints have been greatly improved in terms of material and process, and the life span of artificial joints is getting longer and longer, and more and more patients choose artificial joints, and many of them have solved the pain for many years. However, many people will face some problems before and after joint replacement. The following are the problems we met in the clinic to share with you, hoping to bring some help to you. First, what you need to do before the operation 1, the body will be adjusted to the best state, if the combination of diabetes, coronary heart disease and hypertension and other diseases patients, should be after the internal medicine doctor treatment, the symptoms are under control, and then carry out the operation, do not be in a hurry. 2, preoperative learn to lie in bed stool, urinate, this is very important, because we usually carry out in the toilet, once to the ward, lying in bed, will be very unaccustomed to these actions, many patients have appeared postoperative lying in bed stool, urinate can not be pulled. So 3-5 days before surgery, you can exercise first. 3, preoperative quadriceps and other muscles isometric contraction exercises, the healthy side can be straight leg raising exercises, etc., the purpose is to strengthen the muscle strength, to avoid bedridden lead to atrophy, postoperative also need to carry out these exercises, preoperative to learn. Practice should pay attention to, each muscle contraction need to adhere to about 5 seconds and then relax, do not fast frequency of repetition, the effect is not good, easy to get tired. Each practice to the muscles feel sore and rest, every day can be early in the morning and late at night, each line 3-5 groups, each group 10-15 times. 4, preoperative practice deep breathing, bedridden diet, etc., are for postoperative preparation. 5, the economic aspects should also be in place, because if the cost is not in place, it may lead to surgery can not be carried out, which we all understand. Second, the postoperative problems need to pay attention to 1, after surgery, the affected limb is placed in a neutral position of abduction, generally 20-30 degrees of abduction, with anti-rotation plate to prevent the affected limb from external rotation, which is done to prevent early dislocation. 2. Functional exercises can be performed from the 2nd day after surgery, the details are the same as before surgery. Early exercises can avoid muscle atrophy on the one hand, and promote blood circulation and metabolism on the other hand, which is conducive to the alleviation of distension and disappearance of pain. On the 3rd day after surgery, you can sit on the side of the bed and practice under the doctor’s guidance, and pay attention to avoiding hip flexion of more than 90 degrees when you are sitting, and avoiding flexion of the affected hip, internal and external rotation, which may easily lead to dislocation. 3, the fourth day you can stand from the bed to the ground, do not rush to walk, to adapt to the first, because just stood to the ground is easy to dizziness and other phenomena, which is caused by the position of dizziness, slowly adapt to it. After that, you can start walking slowly, pay attention to walking is a learning experience, to hold on to the walker with both hands, step by step forward, every step forward, the walker to move forward a bit, to avoid the body backward, walking practice, next to a family member must be accompanied, to avoid falls and other occurrences. 4, wound removal is usually 2 weeks after surgery, now if the slow absorption of cosmetic suture words, do not have to worry about the problem of removing the thread. Our patients can be discharged from the hospital 1 week after surgery after the above exercises. Problems to pay attention to after discharge 1. Continue functional activities with the help of a walker for at least 1 month (counting from discharge). After one month, go to the outpatient clinic for rechecking, and you can walk without the walker after the doctor’s consent. 2. Avoid sitting on a low bench within 3 months, avoid hip flexion more than 90 degrees when sitting on a chair, use a higher toilet, and forbid squatting to use the toilet. Avoid the action of crossing your legs, and when you sleep, it is best to put the affected limb in an abducted neutral position, put a thick pillow between your legs, and avoid lying on your side. Generally speaking, after 3 months, you can sleep on your side, but put a thick pillow between your legs. 3.Generally speaking, come to the outpatient clinic for review once in the first, third, sixth and twelfth month after discharge, once in half a year in the second year, and then once a year thereafter, and come to the outpatient clinic at any time if any abnormality occurs.
