What failure assessment actually decides
A failed hip replacement does not automatically mean the whole implant is replaced. According to the American Academy of Orthopaedic Surgeons, revision hip surgery may replace some or all implant components. That single distinction drives everything else: the extent of surgery, the implants required, the length of the operation and how your recovery is planned.
The assessment also has to separate mechanical problems from infection. AAOS notes that infection or bone loss can change reconstruction planning. A loose or worn component is a different problem from a deep infection, and the two are not managed the same way. Bone loss around the implant can also mean the surgeon needs additional reconstruction material or a different fixation strategy.
This is why a remote opinion cannot be a final decision. A surgeon reviewing records can form a view on what is likely, but the definitive assessment often depends on examination, current imaging and sometimes tests that can only be arranged locally. Treat any pre-travel opinion as a planning tool, not as clearance for surgery.
Your practical question is therefore not "do I need revision?" but "what does the surgeon still need to know before they can tell me what revision would involve for me?" That reframing keeps the enquiry honest and gives you a clear list of what to gather.
Which implant and operation records to send first
The most useful starting point is the record of your original operation. Ask the hospital where you had your first hip replacement for the operative note and the implant record. The implant record usually identifies the manufacturer, the model and the lot or serial numbers. Those details matter because the surgeon needs to know what is currently in your body before planning what to remove or retain.
If you have had more than one hip operation, send the notes for each one in date order. A previous revision changes the anatomy and the available bone stock, so the surgeon needs the sequence, not just the most recent report.
Current imaging is the second essential item. Ask your local clinician which imaging is appropriate and how recent it should be; do not assume a particular scan is required. If you already have recent X-rays or other imaging, send the images themselves rather than only the written report, because the surgeon will want to review the films.
Blood tests and any culture results are relevant if infection is a concern. If you have had a hip aspiration or tissue samples taken, include those results. If you have not, that is a question for the assessing clinician, not something to arrange on your own initiative before you have spoken to a surgeon.
A short cover note helps. State your main question in one or two sentences, list your operations with dates, and note any current symptoms such as pain, instability or difficulty weight-bearing. This is not a substitute for the records, but it tells the reviewing team what you are trying to decide.
Whether a staged revision is being proposed, and why
One of the most important questions to ask is whether the surgeon is considering a single-stage or a two-stage revision. In a two-stage approach, the first operation removes the infected or failed components and places a temporary spacer, and a second operation later implants the definitive components. AAOS notes that infection can change reconstruction planning, and staging is one way that change shows up.
If a staged plan is proposed, ask what the interval between stages would be for your case and what has to happen before the second stage goes ahead. The answer depends on infection control, wound healing and your general health, so it is a clinical judgement rather than a fixed schedule. Do not accept a number from anyone who has not assessed you.
Ask what you would be able to do between stages. Weight-bearing status, mobility aids and wound care all affect daily life, and the instructions come from the treating team. If you are planning to travel to China for surgery, you need to understand whether a staged plan would keep you in the country for an extended period or whether part of the interval could be spent elsewhere. That is a logistics question with a clinical input, so ask the surgeon and the coordinating team together.
Also ask what happens if the first stage shows more bone loss or more infection than expected. A good assessment includes a plan B. You do not need a technical explanation, but you should know whether the surgeon would proceed differently and how that would be communicated to you.
How rehabilitation and weight-bearing would be coordinated
Rehabilitation after revision hip surgery is not the same as after a first hip replacement. AAOS notes that individual rehabilitation and weight-bearing instructions matter. That means the plan has to be specific to your operation, your bone quality and what the surgeon actually did.
Ask who will give you the weight-bearing instructions and when. Ask whether you would see a physiotherapist before discharge and how many sessions are anticipated. Ask what equipment you would need, such as crutches or a walker, and whether it can be arranged locally.
If you are travelling from another country, ask how rehabilitation would continue after you return home. The receiving physiotherapist will make their own assessment, so the useful thing to request is a written summary of the operation and the restrictions in place at discharge. Ask the hospital what it can provide and in what language.
Do not treat rehabilitation as an afterthought. If you cannot follow the weight-bearing restrictions safely at home, that affects when you can travel and what support you need. Raise it during planning, not after surgery.
Questions to put in writing before you commit
Put your questions in writing and ask for written answers. This creates a record you can refer back to and reduces the chance of misunderstanding across languages.
Ask which components the surgeon expects to revise and which, if any, might be retained. Ask what imaging and tests are still needed before a plan can be confirmed. Ask whether a staged procedure is being considered and what that would mean for your length of stay. Ask what the rehabilitation and weight-bearing plan would involve and who provides it.
Ask what the written quote covers and what it does not. Do not assume that a figure you have seen online applies to your case. Revision surgery varies with the extent of reconstruction, the implants used and the length of stay, so ask the named hospital for an itemised scope based on your records.
Ask what would make you unsuitable for surgery in China, and what would make the team recommend you stay closer to home. A surgeon who answers that question directly is giving you useful information, not a rejection.
What to do next
Start by gathering your original operative note, implant record and current imaging. Write down your main question and any symptoms that have changed recently. If your pain is severe, you cannot weight-bear, or you have fever or wound discharge, seek local medical care promptly rather than waiting for an overseas enquiry.
You can send a brief summary through the enquiry form, email or WhatsApp. The team will check what you have, identify what is missing and suggest the relevant next step. An initial enquiry is free and does not commit you to a proxy consultation or to treatment.
The hospital and its surgeons decide whether revision is appropriate and what it would involve. Your job is to give them enough information to answer that question properly.
