What Do You Have to Try Before a Joint Replacement?
Patients arrive convinced there is a fixed list of hoops to clear before anyone will operate. There is no universal medical requirement — but there are often insurance requirements, and those are a different thing entirely. Worth separating the two, because one is about your knee and the other is about a form.
Key takeaways
- There is no universal medical checklist that must be completed before a joint replacement.
- Insurers frequently do require documented conservative treatment before authorising surgery, and those requirements vary by plan.
- For mild-to-moderate arthritis, conservative care is genuinely the right first move — not a formality.
- For advanced, bone-on-bone arthritis in a limited patient, months of additional therapy is often paperwork rather than medicine.
- Weight-bearing X-rays plus documented functional limitation are what actually move an authorisation forward — pain with walking and difficulty on stairs, not a pain score.
- Trying things is not wasted even when surgery follows: stronger patients recover better.
The short answer
There is no universal medical checklist you must complete before a joint replacement. No mandatory number of injections. No required months of physical therapy. No age you have to reach.
What actually decides it is how much the arthritis is limiting your life, what a weight-bearing X-ray shows, and whether you are healthy enough for the operation.
Insurance is a separate matter. Many plans require documented conservative treatment before they will authorise surgery, and those requirements vary considerably between them. That is a coverage rule, not a medical one — which means two patients with identical knees can face different hoops purely because of who insures them.
Why the distinction matters
When someone tells you that you “have to” try something first, it is worth asking whether that is a clinical recommendation or an authorisation requirement. Both are real. They are not the same conversation, and they do not deserve the same weight.
Two questions that get confused
Almost every frustrating conversation about this collapses two separate questions into one:
- Is surgery the right treatment for this joint, right now? — a medical question, answered by your symptoms, your imaging, and your health
- Will this plan pay for it yet? — an administrative question, answered by that insurer’s policy document
You can be a clear surgical candidate and still have an authorisation denied. You can also clear every insurance hurdle and still not be someone I would operate on. Keeping the two apart is the difference between a productive conversation and a maddening one.
What genuinely helps — and is worth doing first
For mild-to-moderate arthritis, conservative care is not a delaying tactic. It is the right treatment, and it works often enough that skipping it would be poor medicine.
- Activity modification — substituting what wrecks the joint for what does not, which is not the same as doing less
- Strengthening — the single most underrated intervention, especially the quadriceps for a knee and the glutes for a hip
- Weight management where relevant — each pound is multiplied several times across the knee with every step
- Anti-inflammatories, if you can safely take them
- Injections — cortisone for a flare, hyaluronic acid or PRP for a more durable strategy in the right patient
The depth on each of these lives elsewhere: physical therapy, cortisone, hyaluronic acid, and PRP. This page is about the order and the reasoning, not a repeat of each one.
When it stops being medicine and becomes box-ticking
Here is the part patients rarely hear said out loud.
If a knee is bone-on-bone, the cartilage is gone. No amount of physical therapy regrows it. Strengthening the muscles around a joint with no remaining joint space can help someone tolerate it — genuinely — but it is not treating the problem, and for a patient whose function has visibly narrowed, requiring another twelve weeks of it before anyone will discuss surgery is paperwork rather than care.
The same applies to a mandated injection in a joint that has already failed to respond to two. Repeating a treatment that did not work in order to document that it did not work is not a clinical decision.
One thing worth timing carefully
A steroid injection given close to surgery is associated with a higher infection risk, so most surgeons want a gap between the two. If an injection is being required late in the process purely to satisfy an authorisation, it can end up delaying your operation rather than moving it forward. Ask about timing before you agree to it.
None of this means insurance requirements should be ignored — they have to be worked through. It means you are entitled to know when what you are doing is treatment and when it is documentation.
What is NOT required
- Being a particular age — the decision is driven by function and health, not a birthday
- Being in constant, unbearable pain — a joint that has quietly shrunk your life counts, even if you can still get through the day
- Having tried every injection type that exists
- Using a cane or walker first
- Waiting until the “last possible moment” — a common piece of advice with very little behind it
That last one deserves its own sentence. Implants last far longer than most people assume, and going into an operation weaker, heavier, and more deconditioned than you needed to be is a real cost. Waiting has a price, and it is rarely priced into the advice to wait.
Why trying things is rarely wasted — even when surgery follows
Patients who have decided on surgery often ask why they should bother with therapy in the meantime. The answer is the best argument for conservative care that exists, and it has nothing to do with avoiding the operation.
The muscles you take into a joint replacement are the muscles you rehabilitate with afterwards. Quadriceps strength going in is one of the better predictors of how the first six weeks go. Time spent strengthening while you wait is not time spent postponing — it is the front half of your recovery, done early.
More on that in prehab before joint replacement.
For referring physicians
If you are documenting conservative management with an eventual authorisation in mind, the things that carry weight are:
- Weight-bearing radiographs demonstrating joint space narrowing — standing views, not supine
- A dated record of what was tried and what happened, including failures
- Documented functional limitation — pain with walking, difficulty on stairs, and the activities that have been given up
- Analgesic use and whether it is controlling symptoms
- Relevant medical comorbidities and their control
The one most often missing is functional limitation. A pain score alone is weak; “pain with walking, avoiding stairs, has given up hiking and golf” is far stronger and is a truer description of the problem anyway. Note night pain where it is present — it is a useful flag, though a good many patients who need a replacement never have it.
And a referral does not need to wait until the documentation is complete. Sending the patient in parallel with conservative management usually shortens the whole process rather than lengthening it.
If you feel stuck
If you have worked through the options, your X-ray shows advanced arthritis, your life has visibly narrowed around the joint, and you are still being told to wait — that is worth a second look rather than another cycle of the same thing.
Sometimes the answer really is that it is not time yet, and you deserve to hear that clearly and know why. Sometimes the answer is that you have been waiting for a form rather than for your knee. Either way, a second opinion is a reasonable way to find out which.
Frequently asked questions
What do you have to try before a knee or hip replacement?
Medically, there is no universal checklist. The decision rests on how much the arthritis limits your life, what your imaging shows, and your overall health. Practically, most insurers want to see documented conservative treatment first — commonly some combination of activity modification, anti-inflammatories, physical therapy, and injections over a period of months. Those requirements vary by plan, so the specifics are worth confirming with your insurer rather than assuming.
Does insurance require physical therapy before a joint replacement?
Many plans do, though not all, and the required duration varies. It is one of the most common authorisation requirements alongside a trial of anti-inflammatories and, in some plans, injections. This is a coverage rule rather than a medical rule — which is worth understanding, because it means the answer can differ for two patients with identical knees and different insurance.
Do I have to get injections before I can have a knee replacement?
Not medically, and not under every plan. Where an injection is required, it is usually cortisone or hyaluronic acid. Worth knowing: a steroid injection close to surgery can affect infection risk, so the timing matters and an injection given late in the process can actually delay your operation rather than speed it up.
Do I have to lose weight before a joint replacement?
Some insurers and some surgeons apply weight thresholds, and higher body weight does carry higher rates of certain complications. But this is an individual conversation rather than a universal rule, and it depends on your overall health, not a single number. If you have been told a hard cutoff, it is a fair thing to get a second opinion on.
Is conservative treatment worth it if I know I need surgery eventually?
Often yes, and not for the reason people assume. Strengthening work before surgery — prehab — genuinely improves how the recovery goes, because the quadriceps and hip muscles you take into an operation are the ones you rehabilitate with afterwards. Even when surgery is a certainty, arriving stronger is not wasted effort.
What if I have already tried everything and I am still being told to wait?
That deserves a straight answer rather than another cycle. If you have advanced arthritis on a weight-bearing X-ray, meaningful functional limitation, and you have genuinely worked through conservative options, being told to keep waiting is worth questioning. That is a reasonable moment to get a second opinion.
What documentation helps get a joint replacement authorised?
Weight-bearing radiographs demonstrating joint space narrowing, a record of conservative measures tried with dates and outcomes, and — the piece most often missing — documented functional limitation. Pain with walking, difficulty on stairs, and what the patient has had to give up carry more weight than a pain score on its own. Night pain is a useful flag where it is present, though plenty of patients with significant arthritis never have it.

When Should You See an Orthopedic Surgeon for Knee Pain?
Patients almost always ask whether it is “too early” to see a surgeon. In my experience the opposite is far more common — people arrive having lost years of function they did not need to lose, because they were waiting to be bad enough. You do not need to have failed every treatment, you rarely need an MRI, and you do not need to want surgery. You need a knee problem that has not settled and a straight answer about what is causing it.
