Is It Time for a Hip Replacement?

There is no trigger point

People often arrive expecting to be told they have reached a threshold, that the X-ray has crossed some line, or that the pain has reached a level where surgery becomes necessary.

That threshold does not exist. Hip replacement is an elective operation performed to relieve symptoms and restore function, not to prevent something worse from happening. Nothing is being averted by operating sooner. The hip will not become dangerous.

What that means practically is that this is a decision about quality of life, made by you, with advice. It is not a diagnosis handed down.

What actually informs the decision

The useful markers are functional rather than radiographic.

Walking distance. Not what you can manage once, but what you can do comfortably and repeatedly. Many people track this against something specific, a walk they used to take, a shop they used to reach.

Sleep. Pain that regularly wakes you, or that prevents you finding a comfortable position, is one of the more significant symptoms and one of the more reliable indicators that non-surgical management is no longer holding.

Daily tasks. Socks, shoes, toenails, getting in and out of a car, getting off a low chair. These are specific and measurable, and they change gradually enough that people often underestimate how much has been lost.

What you have given up. This is usually the most revealing question, and often the hardest one. Golf, gardening, a walking group, travel, playing with grandchildren on the floor. People adapt so gradually that the losses accumulate without being noticed as losses.

Medication. Regular reliance on anti-inflammatory medication carries its own risks, and increasing use is a meaningful signal.

What happens if you wait

Waiting is a legitimate choice, and for many people it is the right one. But it is a choice with consequences on both sides, and both should be visible.

Reasons waiting is reasonable. Non-surgical management may still have room to work. Symptoms fluctuate, and a bad period is not always a trend. Every operation carries risk, and an operation not yet needed is risk not yet taken. A replacement has a finite lifespan, so having one at fifty-five means a higher chance of needing revision later than having one at seventy-five.

Reasons prolonged waiting has costs. A long-standing limp changes how load passes through the opposite hip, both knees and the lower back, and secondary problems in those areas can persist after the hip is fixed. Reduced activity leads to loss of muscle strength and general fitness, which affects recovery. Prolonged pain affects sleep, mood and independence. And in some cases the joint becomes stiffer and more deformed, which can make the operation more complex.

There is no formula that resolves this. It is a judgement about your life, and it is worth discussing directly rather than leaving unexamined.

Age, in both directions

"Am I too old?" There is no upper age limit. What matters is medical fitness for anaesthesia and surgery, not the number. Published work indicates that mobility before surgery predicts recovery better than age does, a fit eighty-two-year-old often recovers more quickly than a sixty-five-year-old in poorer general health. Age does affect the risk profile, and that is assessed individually.

"Am I too young?" There is no lower limit either, but the calculation is different. A replacement has a finite lifespan, and younger, more active people place greater demand on it over a lifetime, so the chance of needing revision surgery at some point is higher. That is a reason to explore non-surgical options thoroughly and to be clear about what is being traded, not a reason to endure a decade of significant disability in your fifties. Revision is a real operation with real outcomes; it is simply less good than a first replacement.

What surgery does and does not do

Being clear about this matters more than any other part of the conversation.

What it reliably does: relieves arthritic pain. For most people this is substantial and immediate, the pain that was there before the operation is generally gone when they wake up, and what remains is surgical soreness that settles.

What it usually does: restores walking distance, improves sleep, and returns range of movement enough for daily tasks.

What it does not guarantee: a hip that feels entirely normal. A proportion of people are not fully satisfied with the result despite a technically sound operation and no identifiable complication.

That figure is approximately one in ten for hip replacement, verify against current literature, and it is the single most under-discussed fact in joint replacement.

What it will not do: fix pain coming from somewhere else. If part of your pain originates in the lower back or the outer hip tendons, replacing the joint will not address that part. This is one reason careful assessment matters before committing.

What happens at a consultation

A GP referral is required before a consultation with Professor Rodda.

The consultation covers the history, an examination, and a review of your imaging. If a hip replacement is one of the options, the discussion covers what is involved, which approach and implant would be planned, what recovery would look like for you specifically, and which risks apply particularly to you.

You should leave with a written summary and a written fee estimate, and with the option not to proceed. Nothing needs to be decided in the room.

If you are not ready, that is a legitimate outcome of a consultation. Many people come once, go away for a year or two, and return when the balance has shifted.

Preparing for that conversation

Two things help.

Complete the Oxford Hip Score and bring it. It is a twelve-question survey used internationally to measure how much a hip problem affects daily life. It is not a diagnosis and does not indicate whether surgery is appropriate, but it gives a structured account of your function and a baseline against which change can be measured later.

Write down the specific things you want the hip back for. Not "less pain", the particular things. A walk, a game, a task, a trip. These are what the decision is actually about, and they are what recovery is later measured against.

Questions to ask

• Is my hip the source of all of my pain, or only part of it?

• What would you expect if I waited another year or two?

• What are the specific risks in my case?

• What would recovery realistically look like for someone my age and fitness?

• What would you expect me to be able to do afterwards that I cannot do now?

• What would you expect me not to be able to do?

• What will the total cost be, including hospital, anaesthetist and any excess?

Common questions

How do I know when it's time for a hip replacement?

There is no particular X-ray appearance, age or pain score that determines timing. The practical markers are functional: how far you can walk comfortably, whether pain interrupts your sleep, whether tasks like putting on socks have become difficult, and whether you have given up activities that matter to you. It is a decision made jointly at consultation.

Am I too old for a hip replacement?

There is no upper age limit for hip replacement. What matters is medical fitness for anaesthesia and surgery rather than chronological age, and this is assessed individually. Published work indicates that mobility before surgery predicts recovery better than age. Some older patients recover more quickly than younger patients in poorer general health.

Am I too young for a hip replacement?

There is no lower age limit, but the considerations differ. A replacement has a finite lifespan, and younger, more active people place greater demand on it, so the likelihood of needing revision surgery later is higher. This is a reason to explore non-surgical options thoroughly, not a reason to endure many years of significant disability.

What happens if I delay hip replacement surgery?

Delaying is reasonable and many people do it for years. The costs of prolonged waiting are that a long-standing limp affects the opposite hip, the knees and the lower back; that reduced activity leads to loss of strength and fitness, which affects recovery; and that in some cases the joint becomes stiffer, making the operation more complex.

Will a hip replacement get rid of all my pain?

Hip replacement reliably relieves arthritic pain from the joint, and for most people this is substantial and immediate. It will not address pain originating elsewhere, such as from the lower back or the tendons around the outer hip. A proportion of people are not fully satisfied despite a technically sound operation, which is worth knowing beforehand.

Do I need a GP referral to see an orthopaedic surgeon?

A GP referral is required before a consultation with Professor Rodda. This allows a Medicare rebate to apply to the consultation and ensures your GP remains involved in your care. A referral from another specialist is also acceptable. Telehealth discussions with the nurse navigator, for people travelling from a distance, do not require a referral.
