Revision Hip Replacement: How Long Hips Last and When Surgery Is Needed

Key Takeaways

• Australian registry figures suggest roughly nine in 10 total hip replacements performed for osteoarthritis are still in place 20 years on.
• Loosening, dislocation, infection, fracture and wear reactions cause most revisions, and each tends to show a different pattern of symptoms.
• New groin or thigh pain, instability or fever after a settled recovery deserve early review, because X-ray changes often appear later than symptoms.
• Revision hip replacement asks more of the body than the first operation, so timing, bone stock and your general health shape the plan.

A new hip is meant to hand back the morning walk, the round of golf and a full night’s sleep. Once the pain settles, a quieter question surfaces. How long will it last, and how likely is a revision hip replacement later on?

For most people the answer is reassuring. A revision exchanges part or all of the original implant, and it is needed far less often than patients expect. Problems also tend to show themselves well before anything dramatic happens, so understanding the hip surgery options available, what shortens an implant’s life and which symptoms warrant attention puts you in a stronger position at every review.

Longevity is not one number. It moves with your age at surgery, the reason the joint was replaced, the materials used and how the hip is looked after afterwards. Some factors are settled on the day of surgery. Several are still in your hands.

How Long a Hip Replacement Usually Lasts

Longevity figures come from the Australian Orthopaedic Association National Joint Replacement Registry (AOANJRR), which captures almost every hip replacement performed in the country. They describe large groups of patients, and several factors shift them up or down:

Registry Figures at 10 and 20 Years

AOANJRR reporting on hips replaced for osteoarthritis suggests around 8% have been revised by 20 years, so roughly nine in 10 are still in place two decades on. At 10 years, the revised proportion sits below 5%.

Those 20-year results describe implants and techniques used in the early 2000s. Bearings, head sizes and fixation have improved since, so later results are expected to be at least as good. These percentages describe groups, not individuals.

Age at the Time of Surgery

AOANJRR data suggests around 9% of hips replaced before 55 have been revised by 20 years, with lower rates in people aged over 75. Younger hips are asked to do more, for longer, and their owners live long enough for wear to matter. Age alone is no longer a reason to wait in pain. It is one input into timing, alongside your symptoms, function and daily life.

Diagnosis Behind the Replacement

Hips replaced for osteoarthritis tend to have the lowest rates of further surgery. Replacements performed after a hip fracture, or for rheumatoid arthritis or avascular necrosis, where blood supply to the femoral head has been lost, carry a higher chance of revision. Bone quality, soft tissue condition and the urgency of the original operation all play a part.

Implant Materials and Fixation

Cross-linked polyethylene liners wear far more slowly than the older plastics, which has reduced revisions for wear and loosening. Larger femoral heads have reduced dislocations. Large-head metal-on-metal implants, which shed metal particles at a higher rate, are no longer used in Australia.

Fixation follows the bone. Cemented and hybrid fixation tends to suit older patients and softer bone, while cementless fixation, where bone grows into the implant surface, tends to suit younger patients with denser bone.

General Health and Body Weight

General health shows up in the numbers. Higher anaesthetic risk scores, poorly controlled diabetes, smoking and a body mass index in the upper ranges are each associated with a higher chance of revision, mostly through infection and slower healing. Addressing what can be changed before surgery, with support from your general practitioner (GP) and rehabilitation team, tends to lower that risk.

What Causes a Hip Replacement to Fail

Implants rarely wear out quietly. Failure usually has a mechanism behind it, and each one differs in timing and in how it feels:

Loosening of the Components

Loosening occurs when the bond between implant and bone breaks down, either because fixation was never complete or because wear particles trigger inflammation that resorbs surrounding bone. It is typically a late problem and often starts as pain on standing or taking the first few steps.

Dislocation and Instability

Dislocation is when the ball comes out of the socket. It is one of the more common reasons for early revision and relates to component position, soft tissue tension, head size and weakness in the muscles around the hip. A single dislocation can often be managed without surgery, while repeated episodes usually prompt a closer look at the components.

Infection Around the Implant

Infection is among the most frequent reasons hips are revised in Australia, alongside dislocation and instability. It may appear within weeks of surgery, or years later when bacteria travel through the bloodstream from a dental abscess, a skin wound or a urinary infection.

Fracture Around the Implant

A periprosthetic fracture is a break in the bone around the implant, most often the femur. It can happen during surgery, in the weeks afterwards, or much later after a fall, particularly in bone that has thinned with age. Bone density, implant design and the method of fixation all influence the risk.

Wear Debris and Metal Reactions

Wear develops slowly. Particles released from the bearing surface can provoke an inflammatory response that erodes bone, a process called osteolysis. Metal-on-metal bearings caused this more aggressively, which is why they were withdrawn and why people who received them are still monitored. Similar principles apply when hip resurfacing fails, where the surface implant and the metal ions it releases drive the decision.

Signs That May Point to a Failing Hip Replacement

A settled hip replacement should feel unremarkable. Symptoms that appear after a good stretch of comfort deserve attention, particularly when they persist beyond a couple of weeks:

New or Returning Groin Pain

Groin pain is the classic signal from the socket side of the joint. Pain that arrives with the first few steps, eases, then returns with longer walking can point to loosening. Constant pain, including at rest and overnight, is more concerning and warrants prompt assessment.

Thigh Pain on Weight-Bearing

Pain down the front of the thigh, especially when weight-bearing or climbing stairs, may relate to the femoral stem. Some thigh discomfort is common in the first months after a cementless stem and settles as bone grows in. Thigh pain that starts years later behaves differently and should be reviewed.

Clicking, Catching or Giving Way

Occasional clicking is often harmless. A sense that the hip is shifting, catching or briefly giving way carries more meaning, particularly when rising from a low chair or turning on the leg. These sensations may reflect instability well before a full dislocation.

Redness, Swelling or Fever

Redness, heat, swelling or discharge around the scar, with or without fevers and chills, needs same day medical attention. Late infection can also present as a hip that becomes painful again after years of comfort, without any obvious wound problem.

Changes in Limp or Leg Length

A limp that returns, a feeling that one leg has become shorter, or a hip that no longer tolerates familiar distances are worth raising at review. Changes in walking pattern often appear before pain, and family members sometimes notice them first.

How a Suspected Problem Is Investigated

Working out what is happening inside a replaced hip is a process of narrowing down. Several tests are usually combined, since no single one answers every question:

Reviewing Your History and Symptoms

Your account narrows the field before any test is ordered. When the pain started, whether there was ever a pain-free period after surgery, what makes it worse, and whether there have been dental procedures, infections or falls all point in different directions. Pain that never resolved after the original operation suggests something different from pain that arrived after 12 good years.

Comparing X-rays Over Time

A single X-ray shows less than a series. Comparing current images with films taken soon after surgery shows whether components have shifted, whether lucent lines have appeared at the bone interface and whether bone has thinned around the implant.

Testing Blood and Joint Fluid

Blood tests such as C-reactive protein and erythrocyte sedimentation rate help flag inflammation and possible infection. Where infection is suspected, fluid may be drawn from the joint for culture and cell counts. Identifying the organism before surgery changes the plan considerably.

Adding CT, MRI or Nuclear Scans

Computed tomography (CT) shows bone loss and component position in detail. Magnetic resonance imaging (MRI) with metal artefact reduction sequences can reveal soft tissue reactions, fluid collections and muscle damage. Nuclear medicine bone scans occasionally help when the picture stays unclear.

Measuring Metal Ion Levels

Blood levels of cobalt and chromium may be checked in people with metal-on-metal bearings or certain modular implants. Rising levels, considered alongside symptoms and imaging, form part of the decision about whether the implant should be exchanged.

How the Decision to Revise Is Made

Revision is not automatic once a problem is found. The decision weighs what is happening inside the joint against what is happening in your life:

Symptoms Alongside Imaging Findings

An X-ray showing minor changes in someone walking comfortably may simply be monitored. Significant symptoms with matching findings usually move the conversation towards surgery. Surgeons look for a consistent story across history, examination, imaging and blood results.

Timing and Bone Preservation

Waiting has a cost when bone is being lost, because a new implant needs bone to grip. Revising earlier can mean a simpler operation with more to work with, while waiting stays sensible when findings are stable and symptoms are mild, provided reviews continue.

Fitness for a Longer Operation

Revision surgery takes longer, involves more blood loss and asks more of the body than a first replacement. Heart and lung health, diabetes control, nutrition, smoking and skin condition all feed into the plan, and several are worth improving before a date is set.

Alternatives to a Full Revision

Not every problem needs the whole implant exchanged. A worn liner can sometimes be swapped while a well-fixed shell and stem stay in place. Instability may respond to strengthening or a change in head size. Infection caught very early can occasionally be treated with washout, exchange of the modular parts and antibiotics.

What Revision Hip Replacement Involves

Revision covers a wide range of procedures, from a straightforward liner exchange to a full reconstruction. What is involved depends on the reason for failure and the state of the bone:

Component Exchange and Full Revision

Some revisions replace only the parts that have failed and keep components that remain firmly fixed. Others remove everything, including cement, before rebuilding. Taking out well-fixed implants without damaging bone is one of the more demanding parts of the operation and drives much of the planning.

Single-Stage and Two-Stage Surgery for Infection

Infected joints are handled differently. A single-stage revision removes the implant and inserts a new one in the same operation. A two-stage approach removes the implant, places a temporary spacer loaded with antibiotics, treats the infection over some weeks, then implants the new joint at a second operation. The choice depends on the organism, the state of the tissues and your general health.

Specialised Implants and Bone Grafting

Where bone has been lost, longer stems, larger or augmented sockets, metal wedges and bone graft may be used to create a stable foundation. Dual mobility components are sometimes chosen when instability has been the problem, since the extra articulation adds stability.

Hospital Stay and Early Restrictions

Stays after revision are often a little longer than after a first replacement, and there may be temporary limits on weight-bearing or certain movements, particularly where bone graft or a fracture is involved. Your surgeon sets those limits based on what was found during the operation.

Outcomes and the Chance of Further Surgery

Most people gain meaningful relief from revision surgery, though setting realistic expectations beforehand matters. AOANJRR data also shows revised hips carry a higher chance of needing further surgery than first-time replacements, which is part of why the timing and technique of the original operation carry so much weight.

Recovery and Rehabilitation After Revision Surgery

Rehabilitation after revision follows familiar principles, at a pace that respects what was done inside the joint:

Getting Moving in Hospital

Standing and walking with assistance usually begins within a day or so, guided by any weight-bearing restrictions. Early movement helps circulation, breathing and confidence, and the physiotherapy team works alongside nursing staff to get you moving safely.

Rebuilding Strength Over Months

Strength returns gradually. Gluteal and quadriceps work, balance training and progressive loading form the backbone of the program, typically across several months. Supervised physiotherapy and exercise physiology help match the load to healing tissue without stalling progress.

Returning to Driving, Work and Sport

Driving usually resumes once you can react safely and are off strong pain medication, which your surgeon will confirm. Desk-based work often returns sooner than physical work. Low-impact activity such as walking, swimming, cycling and golf is generally encouraged as you progress, while running and impact sport are approached with more caution after revision.

Timeframes vary with the surgery performed, your bone quality and how rehabilitation goes.

Staying Under Review

Follow-up matters more after revision. Periodic X-rays and appointments allow small changes to be picked up while the options remain simple.

Habits That Support a Long-Lasting Hip

Some influences on implant life were decided in theatre. Others sit with you, and steady habits carry more weight than occasional big efforts:

• Building strength around the hip and thigh two to three times a week, guided by a physiotherapist or exercise physiologist
• Mixing walking, cycling and swimming with resistance work, keeping repeated high-impact loading occasional
• Keeping your weight steady, since every extra kilogram travels through the joint with each step
• Treating dental problems, skin wounds and urinary infections promptly, and telling your dentist you have a joint replacement
• Reporting new pain, clicking, swelling or fever early instead of waiting for the next scheduled visit

The mix that suits you may differ depending on your implant, your bone quality and your other health conditions.

Living With a Hip That Is Doing Its Job

A hip replacement is not a ticking clock. For most Australians it is a one-off operation that quietly does its job for decades, and the small number of hips that do run into trouble tend to signal it early, while the response can still be planned and unhurried.

You can get on with the walking, the travel and the weekends without auditing every twinge. A hip that starts to feel different is a reason to book a review, not a reason to brace for the worst, and revision surgery, when it is needed, is a considered step with a clear purpose.

A review with the team at MTP Health can clarify what is happening in the hip and what to do next. Your GP is also a sound starting point for a referral or for anything that feels urgent.

Frequently Asked Questions (FAQs)

1. How long does a hip replacement usually last?

Australian registry data suggests roughly nine in 10 total hip replacements performed for osteoarthritis are still in place 20 years after surgery. These figures reflect implants used a decade or two ago, and current materials are expected to perform at least as well. Individual results vary with age, activity, bone quality and the reason for the original surgery.

2. What is a revision hip replacement?

A revision hip replacement is an operation that removes some or all of an existing hip implant and replaces it. It ranges from exchanging a worn plastic liner to a full reconstruction using specialised implants and bone graft, depending on what has failed and how much bone remains.

3. Is revision surgery harder than the first hip replacement?

It usually is. Removing implants that are firmly fixed to bone is the demanding part, and recovery can be slower with restrictions lasting longer. Most people still gain meaningful relief from pain and better function.

4. Can a hip replacement be revised more than once?

Yes. Further revisions are possible and are sometimes needed, particularly where infection or significant bone loss is involved. Each operation is planned around what remains, which is one reason surgeons think carefully about the timing of the first revision.

5. How will I know if something is wrong with my hip replacement?

New or returning groin or thigh pain, a limp that will not settle, clicking with a sense of instability, or redness, swelling and fever are the usual signals. Symptoms often appear before X-ray changes, so a hip that feels different is worth reporting even when a recent scan looked fine.

6. Will staying active wear my hip replacement out faster?

Regular activity is generally good for the joint, the surrounding muscles and your overall health. Modern bearings wear slowly, and strong hip and thigh muscles help protect the implant. Repeated high-impact loading is the part usually approached with more caution, and your surgeon or physiotherapist can help you settle on a mix that suits your implant and your goals.

7. Do I need check-ups if my hip feels completely fine?

Periodic review is still worthwhile. X-rays can show early loosening, wear or bone changes before symptoms appear, and picking those up early often keeps the options simpler.

8. How long does recovery take after revision hip replacement?

Early recovery in hospital is usually a few days, with walking aids for several weeks afterwards. Strength and confidence typically build across three to six months, and some people keep noticing gains beyond that. These timeframes are a general guide and depend on the surgery performed and any weight-bearing restrictions.
