1. What is artificial hip revision surgery? A: Artificial hip revision surgery is a remedial surgery for the failure of artificial hip replacement, the procedure mainly includes two parts: the first part is to remove part or all of the original implanted prosthesis; the second part is to reinstall a new prosthesis. 2. What are the common reasons for artificial hip revision surgery? A: The most common reasons for artificial hip revision are loose prosthesis, infection, dislocation, fracture around the prosthesis, etc. 3.What symptoms suggest that the artificial hip joint may need revision? A: For patients who have recovered from artificial hip replacement and can walk and move normally, the presence of pain in the hip or thigh, with or without fever, or the inability to move the hip often indicates a problem with the prosthesis, so you need to contact the surgeon as soon as possible to clarify the cause and take appropriate measures. 4.How to extend the service life of the artificial hip joint after revision? A: Generally speaking, the service life of the prosthesis after artificial hip revision is shorter than that of the initial replacement, mainly because the quality of the patient’s bone tissue is not as strong as that of the initial replacement, with the continuous progress of the revision technology, the current 10-year excellent rate of artificial hip revision has reached more than 80%. The service life of the prosthesis is related to many factors, among which the doctor’s technology is the most important factor affecting the service life of the prosthesis, followed by the suitability of the chosen prosthesis, followed by whether the patient is using it properly, generally speaking: overweight, excessive activity, etc. are all unfavorable factors affecting the service life of the prosthesis. 5.What are the requirements for the review after the artificial hip revision? A: Just like a car needs annual examination, for each case of artificial hip replacement and revision, in order to avoid the artificial joint “working with disease”, regular review is essential, including: whether the pain, walking gait, hip function, x-ray to understand the position and stability of the prosthesis, etc., and sometimes also need to make Hematological examination (blood sedimentation, C-reactive protein), CT, ECT (isotope bone scan), etc. Review method: Patients come to the hospital for examination or, with the surgeon’s permission, patients take X-rays at the local hospital and send them to the surgeon, while informing the recovery situation by phone or e-mail. 6.How many times can the artificial hip joint be revised? A: Theoretically, there is no upper limit to the number of times the artificial hip can be revised, and there have been many successful cases of the third and fourth revision in our hospital. 7.How to choose a suitable artificial hip joint revision prosthesis? A: The success of artificial hip revision, in addition to the surgeon’s surgical technique, depends largely on whether the prosthesis is selected correctly. Of course, due to the complexity and certainty of the revision surgery, several sets of surgical plans and different revision prostheses will be prepared, including other tools and materials to deal with possible complications during the surgery, such as straps, allograft bone, plates, etc. to deal with periprosthetic fractures. 8.What are the common complications of artificial hip revision surgery? A: Complications of artificial hip revision surgery are generally higher than those of initial replacement. Early complications include: dislocation, periprosthetic fracture, infection, unequal length of lower limb, etc. Late complications include: loosening, infection, dislocation, osteolysis, etc. 9.How to deal with the infection after the artificial hip revision? A: Although there are a series of strict measures to prevent infection, the incidence of infection after artificial joint revision is by far higher than that of the initial replacement, and any periprosthetic infection is a very serious complication that is very difficult to treat. The majority of infections require two or even more revisions by completely removing the prosthesis, installing a temporary antibiotic-containing bone cement prosthesis, and waiting for weeks to months for the infection to be fully controlled before re-installing the prosthesis. 10.What are the advantages of the artificial hip revision surgery in your hospital? A: Our orthopedics department is the only key specialty of Chinese medicine hip and joint disease in China, which was founded in the 1980s by Professor Yuan Hao, a famous orthopedic specialist combining Chinese and Western medicine. The comprehensive diagnosis and treatment level of hip joint diseases such as femoral head necrosis has reached the leading level in China, and the number of hip joint diseases such as femoral head necrosis admitted and treated each year is the highest in the industry. At the same time, our hospital is also one of the first specialties in China to introduce modern THA technology, and the quantity and quality of initial THA and revision carried out every year are not only at the forefront in South China, but also at the advanced level in China, and have Chinese medical characteristics in post-operative complication prevention and rehabilitation promotion, which improve the efficacy and win the trust of patients.
