Hip Replacement: How Do You Know When You Need One?
Being told that you have hip osteoarthritis does not automatically mean that you need a hip replacement.
Even being told that the osteoarthritis is severe on an X ray does not make that decision for you.
For some people, hip replacement can be transformative. Pain has become difficult to manage, everyday activities are increasingly restricted and appropriately delivered conservative treatment is no longer providing an acceptable quality of life.
For others, an X ray may show advanced osteoarthritis while symptoms remain manageable and they continue doing most of the things that matter to them.
Age should not make the decision either. The old idea that someone should simply tolerate years of significant pain and restriction because they are “too young” for a hip replacement is increasingly difficult to justify. NICE specifically advises that age should not be used as a barrier to referral for joint replacement.
The decision is therefore not simply about how the hip looks or how old you are.
It is about the relationship between your symptoms, function, quality of life, clinical findings, previous treatment, expectations and what matters to you.

What is hip osteoarthritis?
Hip osteoarthritis is a condition affecting the whole joint.
Changes can occur within the cartilage, underlying bone, joint lining and surrounding tissues. Over time, these changes can be associated with pain, stiffness and reduced function.
Typical symptoms can include pain around the groin or front of the hip, stiffness, reduced movement and increasing difficulty with activities such as walking, putting on shoes and socks, getting in and out of a car or climbing stairs.
However, not everybody with hip osteoarthritis experiences the same symptoms.
The severity of symptoms also does not always correspond neatly with the severity of changes seen on an X ray.
That distinction becomes particularly important when deciding whether someone needs surgery.
Does severe hip osteoarthritis mean you need a hip replacement?
No.
Severe osteoarthritis on an X ray tells us that there are significant structural changes within the joint.
It does not independently tell us whether someone needs a hip replacement.
Imagine two people with very similar X rays.
One is struggling to walk for ten minutes, regularly wakes because of pain, cannot put their shoes on comfortably and has stopped participating in activities that are important to them.
The other has some stiffness and discomfort but continues walking, exercising, sleeping well and doing almost everything they want to do.
Their X rays might look similar.
Their need for surgery may be completely different.
This is why treating the X ray rather than the person can lead to poor decision making.
What symptoms matter when considering hip replacement?
Pain obviously matters, but the decision is broader than simply asking someone to rate their pain out of ten.
We need to understand what the hip is preventing you from doing.
Questions might include:
How far can you comfortably walk?
Is pain disturbing your sleep?
Are you struggling with stairs?
Can you put your shoes and socks on?
Is the hip affecting your work?
Have you stopped exercising or participating in hobbies?
Is it affecting your relationships or social life?
Are you having more bad days than good?
How much medication are you requiring to manage the symptoms?
How acceptable is your current quality of life?
These questions tell us considerably more about the impact of the condition than an X ray alone.
Someone does not need to wait until they are completely disabled before considering surgery.
Equally, the presence of significant osteoarthritis does not mean somebody needs an operation while their symptoms remain acceptable to them.
Should the X ray determine whether you need surgery?
An X ray is an important part of the assessment when hip replacement is being considered.
It can confirm the presence and severity of osteoarthritis and help establish whether the structural findings correspond with the clinical presentation.
But it remains one part of the decision.
Imaging provides information about structure.
The clinical assessment tells us what that information means for the person.
If someone has advanced hip osteoarthritis on X ray, restricted hip movement, typical hip symptoms and substantial functional limitation, the different pieces of information fit together well.
If the symptoms do not fit the imaging findings, further clinical reasoning may be required.
Not every pain around the hip comes from the hip joint itself. Lateral hip pain, problems arising from the lumbar spine and other musculoskeletal conditions can produce symptoms around a similar area.
Before making major treatment decisions, we therefore need reasonable confidence that we are treating the correct problem.
What should you try before considering hip replacement?
For most people with hip osteoarthritis, conservative management should be appropriately explored before surgery.
This does not mean everyone needs to complete an arbitrary number of physiotherapy sessions before they are allowed an orthopaedic opinion.
It means understanding whether there are reasonable opportunities to improve symptoms and function without an operation.
Exercise is an important part of this.
Depending on the individual, rehabilitation might address hip and lower limb strength, general physical capacity, movement and tolerance to the activities that are currently difficult.
Medication may have a role and can be discussed with an appropriate healthcare professional. Weight management can also be relevant for some people, but should be considered individually rather than treated as a blanket recommendation.
Most importantly, conservative management needs to reflect the individual.
A generic exercise sheet may contain perfectly reasonable exercises, but optimising rehabilitation involves considerably more than choosing the exercises themselves.
Load, dosage, progression, symptom response and the person's goals all matter.
Does physiotherapy still help if you have severe hip osteoarthritis?
Potentially, yes.
People are sometimes told that their hip is too arthritic for physiotherapy to help.
Physiotherapy cannot reverse the structural osteoarthritis seen on an X ray.
But that is not necessarily what successful treatment needs to achieve.
If someone becomes stronger, walks further, sleeps better and returns to activities that matter to them, their condition has meaningfully improved even though their X ray remains unchanged.
This was sent to me by a follower on social media who had found some of my posts helpful. It's a section from his orthopaedic clinic letter in relation to his advanced hip osteoarthritis. He wanted to share it to help other people in similar situations.
For some people, appropriately optimised conservative management can delay or potentially avoid the need for surgery.
For others, it provides insufficient improvement and hip replacement remains the most appropriate option.
Neither outcome represents a failure.
The purpose of conservative management is to establish what can realistically be achieved without surgery and whether that outcome is acceptable to the individual.
When might a hip injection be appropriate?
Injections can sometimes form part of the management of hip osteoarthritis.
However, they should not automatically be viewed as the step between physiotherapy and surgery.
The useful questions are:
What are we trying to achieve?
How likely is the injection to help?
How long might the benefit last?
What are the potential risks?
What happens afterwards?
In some situations, an injection may also provide useful diagnostic information where there is uncertainty about whether symptoms are genuinely arising from the hip joint.
Whether an injection is appropriate therefore depends on the individual clinical picture.
How do you know when it is time for a hip replacement?
There is no single threshold.
You do not suddenly qualify for a hip replacement because an X ray reaches a particular level of severity or because your pain reaches a certain number out of ten.
The decision becomes increasingly reasonable when several things come together.
You have symptoms consistent with hip osteoarthritis.
Those symptoms are having a meaningful impact on your quality of life.
Activities that matter to you are becoming increasingly difficult.
Appropriate conservative management is no longer providing an acceptable level of function.
The imaging and clinical findings support the diagnosis.
You understand the potential benefits and risks of surgery.
And importantly, you feel that your current situation is no longer acceptable enough to continue managing without surgery.
Hip replacement is an elective procedure. The decision is ultimately about whether the potential improvement is worth the risks, recovery and consequences of having an operation.
That balance will not be identical for everyone.
Are you too young for a hip replacement?
This is a question that deserves more consideration than simply being given an age cut off.
Historically, younger people with hip osteoarthritis were sometimes advised to delay hip replacement for as long as possible because the implant might eventually wear out and require revision.
There is some logic behind that concern.
A person having a hip replacement at 50 has considerably more years ahead of them in which that implant could eventually require further surgery than someone having the same operation at 80.
But that is only one side of the decision.
There is also a cost to delaying surgery.
If somebody spends ten years with substantial pain, poor sleep, declining physical activity, difficulty working and an inability to participate properly in family or social life, those years matter too.
NICE specifically recommends that people should not be excluded from referral for joint replacement because of age.
So rather than asking only:
Can we delay the hip replacement?
We should also ask:
What is the impact of delaying it?
Being younger does not automatically mean someone should have surgery.
But neither should it mean accepting an unnecessarily poor quality of life purely to reach an arbitrary age.
How long does a hip replacement last?
This is usually the concern sitting behind the advice to delay surgery.
There is no expiry date for a hip replacement.
Implant longevity varies according to factors including the implant itself, surgical technique, patient characteristics and what happens over the following decades.
However, modern hip replacements generally last considerably longer than many people assume.
Long term studies and joint replacement registries show excellent survivorship beyond 15 and 20 years, with many hip replacements continuing to function substantially longer. More recent evidence is also allowing us to estimate outcomes extending towards 30 years.
This does not remove the issue of revision surgery, particularly for somebody having a replacement relatively young.
But telling someone that a hip replacement simply “lasts 10 years” or “lasts 15 years” is no longer an adequate way of describing the evidence.
The possibility of future revision needs to be balanced against the potential benefit of restoring years of function and quality of life now.
What can you do after a hip replacement?
For many people considering hip replacement, this matters just as much as pain relief.
The aim is often not simply to walk around the house comfortably.
People want to walk significant distances, travel, work, play golf, cycle, exercise, hike and get back to the activities that make their life enjoyable.
Return to recreational activity following total hip replacement is generally high, with systematic review evidence reporting return to sport in a substantial majority of patients.
Walking, cycling, swimming, golf and gym based exercise are commonly achievable following recovery.
Higher impact sports require more individual consideration. Recommendations vary according to previous experience, implant, surgeon preference and the particular demands of the activity, and the evidence around very high impact activity and long term implant survival remains less certain.
This is another reason decisions around hip replacement should be individualised.
A younger active person may place enormous value on returning to hiking, cycling or golf.
That desired level of function should be part of the discussion rather than assuming that being able to manage basic everyday activities represents a satisfactory outcome for everyone.
What does the NHS hip osteoarthritis decision tool recommend considering?
NHS England has produced a useful decision support tool specifically for people with hip osteoarthritis.
Rather than asking only about the X ray, it encourages people to think about whether:
Pain feels unmanageable
Pain interferes with sleep
Symptoms affect mental wellbeing
There are more bad days than good days
Everyday activities have become difficult
Symptoms are affecting work
The hip is limiting time spent with family and friends
That is a much better representation of how decisions about hip replacement should be made.
The tool does not tell you whether you should have surgery. It is designed to help you consider the available options alongside your own circumstances, preferences and values.
It can be particularly useful to look through before discussing your options with a healthcare professional.
When should you get an orthopaedic opinion?
An orthopaedic opinion becomes appropriate when there is a genuine question about whether hip replacement or another surgical intervention should be considered.
You do not necessarily need to exhaust every conceivable conservative treatment first.
Equally, being diagnosed with severe osteoarthritis does not automatically mean that the next step must be a surgeon.
If symptoms remain manageable and there is still realistic scope to improve conservative management, continuing without surgery may be entirely reasonable.
If pain and functional limitation are substantially affecting quality of life despite appropriate conservative care, obtaining an orthopaedic opinion makes sense.
The orthopaedic surgeon can then assess whether hip replacement is technically and medically appropriate and discuss the potential benefits, risks and expected recovery.
What if you are still unsure?
This is where the reasoning and balance of an Advanced Physiotherapy assessment can be particularly useful.
The role is not to persuade somebody to avoid a hip replacement.
Nor is it to decide that somebody needs surgery simply because their X ray looks severe.
It is also not to delay an appropriate orthopaedic opinion simply because somebody is relatively young.
The first task is to understand the diagnosis, symptoms, functional limitations, previous treatment and what the individual actually wants to be able to do.
From there, we can consider whether conservative management has genuinely been optimised, whether further investigation or an injection might add something, or whether the most appropriate next step is an orthopaedic opinion.
Sometimes there is considerably more that can be done conservatively.
Sometimes the person is functioning remarkably well despite significant osteoarthritis.
And sometimes continuing to delay an orthopaedic opinion is unlikely to improve the situation.
That is the balance.
At Genuine Physio in Tadworth, near Kingswood, my role as an Advanced Physiotherapist is to help people understand where they are within that decision making process and what the most appropriate next step is for them.
Frequently Asked Questions
Does severe hip osteoarthritis always need surgery?
No. The severity of osteoarthritis on an X ray is only one part of the decision. Symptoms, function, quality of life, response to conservative management, overall health and personal preference all matter.
Am I too young for a hip replacement?
Age alone should not prevent someone from being referred for consideration of hip replacement. The potential lifetime risk of revision needs to be balanced against the impact that delaying surgery may have on pain, function and quality of life.
How long does a hip replacement last?
There is no fixed lifespan. Modern hip replacements commonly survive well beyond 15 to 20 years, and many continue functioning for considerably longer. Individual outcomes vary and younger patients have a greater lifetime possibility of eventually requiring revision surgery.
Can I exercise after a hip replacement?
Yes. Many people return to walking, cycling, swimming, golf, gym based exercise and other recreational activities following hip replacement. Higher impact sports require more individual discussion.
Can physiotherapy prevent a hip replacement?
For some people, conservative management can improve symptoms sufficiently that surgery is delayed or no longer feels necessary. For others, symptoms remain unacceptable despite appropriate rehabilitation and hip replacement becomes the right option.
Should I wait until my hip pain is unbearable before having a replacement?
No. You do not need to wait until symptoms become unbearable. The decision should consider how significantly the hip is affecting your life, what treatment has already been tried and whether the potential benefits of surgery now outweigh the disadvantages and risks for you.
Should I see a physiotherapist or orthopaedic consultant about hip osteoarthritis?
It depends on the question you need answered. If you are unsure about the diagnosis, whether conservative management has been optimised or whether surgery is necessary, an experienced musculoskeletal assessment can be useful. If there is already a clear question about proceeding with hip replacement, an orthopaedic opinion is appropriate.
Is there a test that tells me whether I need a hip replacement?
No single test can make the decision for you. The NHS hip osteoarthritis decision support tool can help you consider how symptoms are affecting different aspects of your life and prepare for a shared decision making discussion.
Unsure whether it is time to consider a hip replacement?
If you have hip osteoarthritis and are unsure whether you should continue with conservative management, consider other options or seek an orthopaedic opinion, get in touch with Genuine Physio.
A detailed assessment can help establish how much of your current problem is being driven by the hip, what has already been tried and whether there is still meaningful scope to improve without surgery.
If an orthopaedic opinion is the appropriate next step, that should be recognised too.
The aim is not to avoid hip replacement or delay it because of your age.
It is to help you make the right decision at the right time.
