Revision Hip Replacement

What is Revision Hip Replacement?

Revision hip replacement is surgery to replace or repair part or all of a previous hip replacement. While modern hip replacements are highly durable and most last many years, no implant lasts indefinitely, and in some cases a hip replacement may wear out, loosen, become unstable, or develop other problems over time. Revision surgery addresses these issues by replacing or rebuilding the affected components.

Revision surgery is generally more complex than the original (primary) hip replacement. It often involves working with bone that has changed since the first operation and requires specialised techniques and implants. Careful assessment to identify the precise reason for revision is essential to planning the procedure.

Why a Hip Replacement Might Need Revision

Reasons a hip replacement may require revision include:

• Loosening: one or more components losing their secure fixation over time
• Wear: wear of the bearing surfaces over many years
• Instability or dislocation: recurrent dislocation of the joint
• Infection: which requires specific assessment and management
• Fracture: of the bone around the implant (periprosthetic fracture)
• Other component-related problems

Assessment and Diagnosis

Identifying the exact cause is the most important step before revision surgery. Assessment typically includes:

• A detailed history and clinical examination
• X-rays to assess the position and fixation of the components
• Blood tests to screen for infection
• Sampling of fluid from the joint where infection is being assessed
• Further imaging where needed to evaluate loosening, bone loss, or component position

Because the right operation depends entirely on the cause, revision is planned around the specific problem identified.

The Procedure

Revision surgery varies widely depending on the problem. It may involve replacing a single component (such as the worn bearing surface) or a more extensive reconstruction of both the socket and the femoral side, sometimes with bone grafting or specialised implants to address bone loss. Where infection is the cause, management may involve more than one stage. Surgery is performed under spinal or general anaesthesia, and the complexity and length depend on the individual case. The specifics of your procedure will be explained to you at your consultation.

Recovery

Recovery after revision hip replacement is generally more variable and sometimes more prolonged than after a primary hip replacement, reflecting the greater complexity of the surgery and the condition of the bone and tissues. A structured, individualised rehabilitation programme is important, and your recovery plan will be tailored to the procedure performed and your progress.

Risks and Complications

Revision surgery carries the risks of hip replacement in general, and these risks are generally higher than for primary surgery given the increased complexity. They include:

• Infection
• Blood clots (deep vein thrombosis or pulmonary embolism)
• Bleeding
• Dislocation
• Fracture
• Bone loss requiring grafting or specialised implants
• Leg length inequality
• Injury to adjacent nerves or blood vessels
• Further loosening or the need for additional surgery in the future

All relevant risks will be discussed in detail at your consultation.

Frequently Asked Questions

Why is revision surgery more complex than the first operation?

Revision surgery involves removing or working around existing implants, dealing with bone that has changed since the first operation, and sometimes addressing bone loss. This often requires specialised techniques and implants, making it more complex than the original procedure.

Why is finding the cause so important before revision?

The right revision operation depends entirely on the underlying problem — loosening, wear, instability, infection, or fracture each require a different plan. A thorough assessment to identify the cause is therefore essential before surgery.

Will my recovery be longer than my first hip replacement?

Recovery after revision surgery is often more variable and can be more prolonged than after a primary hip replacement, reflecting the greater complexity. Your recovery plan will be tailored to the specific procedure and your individual progress.
