Revision Hip Replacement
A revision total hip replacement is a “redo” operation on a hip that already has an artificial joint. It may involve changing one part (for example, the cup or the stem) or the whole hip replacement, depending on the problem.
Causes
Data from the Australian Orthopaedic Association National Joint Replacement Registry (AOANJRR) – which tracks almost all hip replacements done in Australia – shows that the most common reasons for revising a hip replacement are:
- Loosening or wear of the implant
- Infection around the prosthesis
- Dislocation or ongoing instability of the hip
- Fracture around the implant (periprosthetic fracture)
Less common reasons include leg-length issues, persistent pain, or problems with specific older implant designs.

How long do hip replacements last?
The AOANJRR provides very reassuring long-term data:
- When the Registry looks just at modern implants that are still in use, many commonly used designs have revision rates well under 10% at 20 years. AOANJRR
- The proportion of hip procedures that are revision operations each year (the “revision burden”) has fallen over time and is now about 7%, the lowest ever reported by the Registry, reflecting better implants and techniques. AOANJRR
In simple terms:
- For the vast majority of people, a hip replacement is expected to last at least 20 years, and often for the rest of their life.
- Your own risk of ever needing revision depends on factors like age, activity level, bone quality, general health and the specific implant used.
Treatment
Revision hip surgery is usually more complex than the first (primary) hip replacement because:
- There may be bone loss or scar tissue.
- Special implants, bone grafts or reconstruction techniques might be required.
- Surgery and recovery can take longer, with a slightly higher risk of complications.
Despite this, revision surgery can still be very successful at:
- Reducing pain
- Improving function
- Restoring stability and confidence in the hip
Your surgeon will discuss your individual risks and benefits in detail if revision is being considered.
Recovery
You can help your hip last as long as possible by:
- Keeping a healthy weight
- Staying active with low-impact exercise (walking, cycling, swimming)
- Avoiding high-risk activities that may cause falls or major trauma
- Controlling medical conditions such as diabetes and osteoporosis
- Seeing your surgeon or GP if you develop new pain, instability, or loss of function
Will I definitely need a revision one Day?
No. Most people never need a revision.
AOANJRR data clearly shows that most hip replacements are still functioning well many years later, especially with modern prostheses and good surgical technique. AOANJRR+1
You are more likely to need revision if:
- You are very young and very active at the time of the first hip replacement.
- You develop a complication such as infection, recurrent dislocation, or fracture.
Minimising your risk of needing a revision
Prevention is the best medicine and so minimising reversible risk factors prior to surgery is the most important step.
This involves keeping your weight and blood sugars in an acceptable range. Delaying surgery if the skin is injured or you are unwell.
