A total hip joint replacement may need to be revised (changed) if it is causing significant symptoms.  This may be a result of infection, repeated dislocation, loosening of the implant, excessive wear or pain. Fortunately, this surgery is rarely required, occurring in only 4% of joints after 10 years. The operation is often complex with the extent of surgery depending on the severity of the underlying problem. 

 

Extensive investigation is required before considering revision surgery.  This usually includes blood tests to exclude infection, XR imaging of the pelvis, a bone scan and occasionally a CT scan. Once the issue is diagnosed, a plan is formulated to deal with the symptoms.
