Revision Hip Replacement
REVISION HIP REPLACEMENT
While most hip replacements last many years, some can develop problems over time that require further surgery. Revision hip replacement is a procedure to remove and replace part or all of the original implant when it has failed, worn out, or is causing persistent symptoms.
Dr Darren Paterson performs revision hip replacement for patients across the North Shore, Northern Beaches, Tamworth, and Central Coast NSW. Each surgery is carefully planned to address the cause of the problem, restore hip stability and movement, and allow a return to comfortable daily activities.
Why a hip replacement might require revision
A hip replacement may need revision surgery for a number of reasons, including:
Implant wear or loosening – Over time, components may loosen from the bone or wear down.
Infection – Infection within the joint may cause pain, swelling, and instability, sometimes requiring staged surgery.
Recurrent dislocation – Soft tissue laxity or malpositioned components can lead to repeated hip dislocations.
Fracture around the implant – Trauma or weakened bone can cause a periprosthetic fracture.
Osteolysis (bone loss) – The body’s reaction to implant wear particles may cause bone loss, compromising stability.
Persistent pain or stiffness – Mechanical problems, scar tissue, or unrecognised pathology may require revision.
Assessment before revision surgery
Before recommending revision hip replacement, Dr Paterson will carry out a thorough assessment that may include:
- Reviewing your medical and surgical history
- Examining your hip function, stability, and walking pattern
- Ordering X-rays, CT, or MRI to assess the position and condition of your implants
- Blood tests to check for infection or inflammation
- Joint aspiration (sampling joint fluid) where infection is suspected
This information is essential to accurately diagnose the problem and plan the most appropriate surgical approach.
The revision hip replacement procedure
Revision hip replacement is often more complex than the initial surgery and requires specialised implants and techniques. Steps may include:
- Removal of the old implant – Performed carefully to minimise bone loss and preserve surrounding structures.
- Treatment of underlying problems – For example, debridement of infected tissue, bone grafting for bone loss, or adjusting component alignment.
- Placement of new components – Specialised revision implants may have longer stems, reinforced fixation, or dual mobility bearings to improve stability.
- Final checks – Leg length, stability, and hip movement are assessed before closure.
Recovery after revision hip replacement
Recovery can take longer than after a primary hip replacement, especially if the surgery was complex or addressed bone loss or infection. In general:
- Hospital stay: 3–5 days
- Weight-bearing: May be immediate or delayed depending on the stability of the new implant and bone quality
- Physiotherapy: Begins in hospital and continues after discharge to restore strength, stability, and mobility
- Return to activities: Light daily activities may resume within 6–8 weeks; full recovery can take 6–12 months
Dr Paterson will work with your rehabilitation team to tailor your recovery program to your needs and surgical outcome.
Risks and considerations
All surgery carries risks, and revision hip replacement is more complex than primary surgery. Potential risks include:
- Infection
- Blood clots
- Dislocation
- Loosening or wear of the new implant over time
- Nerve or blood vessel injury
- Leg length difference
Dr Paterson will discuss these risks with you and explain the steps taken to reduce them.
Is revision hip replacement right for you?
Not all patients with hip pain require surgery. During your consultation, Dr Paterson will review your symptoms, imaging, and lifestyle needs to help determine if total hip replacement is the most appropriate option, or whether joint-preserving treatments may be more suitable.
