What is Revision Hip Replacement?
Revision hip replacement surgery involves the removal and replacement of a previously implanted hip prosthesis. Unlike a primary (first-time) hip replacement, revision surgery is technically more complex, as it must address both the removal of the existing implant and any bone or soft tissue changes that have occurred since the original operation.
Mr Dennis Kosuge has developed particular expertise in revision hip replacement surgery, including the management of severe acetabular (socket) defects. He was co-author of an award-winning presentation on this topic at the American Academy of Orthopaedic Surgeons (AAOS) in 2019. He operates at The Rivers Hospital, Sawbridgeworth and The Princess Alexandra Hospital, Harlow, serving patients from across Essex and Hertfordshire.
Why Might a Hip Replacement Need to Be Revised?
Hip replacements are designed to last many years, but they may fail for a variety of reasons. Common causes for revision surgery include:
Aseptic loosening — the implant becomes loose over time as the bond between the prosthesis and the bone deteriorates
Periprosthetic joint infection (PJI) — bacterial infection around the implant
Instability and dislocation — recurrent episodes of the hip joint coming out of position
Bearing surface wear — gradual wearing of the cup or head component over time
Periprosthetic fracture — a fracture of the bone around the implant, often following a fall
Adverse reactions to metal debris (in older metal-on-metal implants)
Implant fracture
In some cases, patients may experience ongoing pain after a hip replacement without a clearly identified cause. Thorough investigation is required before any decision to revise is made.
Assessment and Planning
Revision hip surgery requires careful pre-operative planning. Mr Kosuge will arrange a thorough assessment including blood tests (to screen for infection), advanced imaging (X-ray, CT, and sometimes nuclear medicine scans), and in selected cases, joint aspiration to exclude or confirm infection. This information is used to understand the nature and extent of the problem and to plan the most appropriate surgical strategy.
The Procedure
The specifics of revision hip replacement surgery depend entirely on the underlying cause of failure and the extent of any bone loss. The procedure may involve replacing only one component (for example, the cup or the stem) or both components. In cases of significant bone loss, bone grafting or the use of specialist augmentation devices may be required. Mr Kosuge will be delighted to explain the planned procedure fully during your consultation.
