Revision hip replacement starts with identifying why the original hip is failing. Pain alone is not enough. The surgeon may need X-rays, prior operative records, implant information, blood tests for infection screening, advanced imaging, and sometimes joint aspiration.
The plan changes significantly depending on whether the problem is loosening, instability, infection, fracture, implant wear, abductor weakness, or bone loss. Each cause leads to a different reconstruction strategy.
Ask during consultation: What is the suspected reason my hip replacement is failing, what tests are still needed, and how much of the implant might need to be revised?
