Patient: right hip and knee pain can not walk freely without any treatment I am 36 years old, I feel more pain in my right hip and knee after walking for a long time, a few days ago in the local hospital, the film and MRI confirmed the diagnosis of congenital hip dysplasia, subluxation, aseptic necrosis of the right femoral head, the doctor said it is best to replace the artificial hip, but the service life is only 10-15 years, I would like to ask the doctor: 1. 1) Is there any artificial hip with a longer service life, such as 30 years; 2) Will it fall off after replacement, because I have heard of people who need to have it reassembled after less than a year; 3) If the pain is tolerable and I don’t have to walk too much to do heavy work, can I postpone it for a few years? What is the essential difference between early and late replacement? What are the serious consequences of late replacement? Do I need to take rejection drugs? Are there any other after-effects? Or is it a mismatch? Is the aftercare not scientific? Or is it that a large percentage of hip replacements fall off? I look forward to the doctor’s reply. Hospital orthopedics: congenital hip dysplasia is very common in the Department of Arthroplasty, will have a great impact on the patient’s quality of life, now the only way to completely solve the problem is to perform artificial hip replacement surgery, the answer to your question: 1, now the surgical technique of artificial joint replacement and the quality of the joint are guaranteed, it is recommended that you use imported ceramic or gold-to-gold joints, according to the literature According to the literature, the ten-year survival rate of good joints is more than 95%. There are many factors that affect the life of a joint, not just the quality of the joint. 2. Most failures within a short period of time after surgery are related to surgical techniques, so it is recommended that you find an experienced surgeon to operate. 3. Your quality of life is already very poor, if you delay the surgery for a few years later, resulting in the loss of joint function, it will make the future surgery more difficult, recovery is difficult, and the effect of surgery will be greatly discounted. The main problem for you is that you are still young and may have to face a second surgery in the future, but now the surgery technology is very mature, there is no need to worry about 20 or 30 years later, there is no need to take anti-rejection drugs after joint replacement. 5. A common complication after joint replacement surgery is joint dislocation, if the surgical technique is excellent, there is usually no problem, in addition, the post-operative rehabilitation exercise is also very important, this concept is different in each hospital, good rehabilitation exercise can make the function of the joint better recovery. Patient: Thank you very much, Dr. Zhang, for replying to me in your busy schedule. How long does the surgery take? 2. Is there much bleeding from the beginning of the surgery to a few days after the surgery? 3. How long will it take to get out of bed with crutches? How long will it take to go to the bathroom on your own with crutches? I am very afraid to lie down for a long time to urinate and defecate because there is nothing I can serve at home, so I am looking forward to Dr. Zhang’s reply, thank you very much. Regular hip surgery can usually be finished within an hour, but if it is more complicated, it may take a little longer. 2, individual patients may have a bit of bleeding from the wound for a day or two after surgery, but the vast majority will not have too much bleeding, and many surgeries we can now do without drainage. 3, postoperative pain is mainly one or two days after surgery, we will have a lot of postoperative analgesic methods, pain should not be too serious, the time to get out of bed we are relatively conservative, the general situation is about a week can get out of bed activities, the time to go to the toilet depends on the situation of surgery, can not be generalized. 4, in our hospital from hospitalization to discharge generally about ten days, that is, 5-7 days after surgery can be discharged. 5, a period of time after surgery, urination and defecation have to be in bed, this is an important time for soft tissue repair, but also the most vulnerable to dislocation, it is better to be careful.
