What If Physiotherapy Isn’t Enough for Knee Arthritis?
You have knee osteoarthritis.
You tried physiotherapy.
You did the exercises.
But your knee still hurts.
So what happens next?
Should you:
Continue physiotherapy?
Get an injection?
Try shockwave?
Have an MRI?
See a specialist?
Consider knee replacement?
The answer should not automatically be any one of these.
If appropriate physiotherapy has not produced sufficient improvement, the next step should usually be:
REASSESS.
At The Pain Relief Clinic, our approach is not:
“Physiotherapy didn’t work, so buy more physiotherapy.”
Instead, we ask:
Why hasn’t the knee improved?
The answer helps determine what should happen next.
First: Did Physiotherapy Really Fail?
This may sound like an unusual question.
But saying:
“I’ve tried physiotherapy.”
can mean many different things.
One patient may have completed a progressive strengthening programme over several weeks.
Another may have attended two sessions consisting mainly of massage and passive treatment.
Another may have received exercises but rarely performed them.
Another may have exercised consistently but pain prevented meaningful progression.
These are very different situations.
Before declaring physiotherapy unsuccessful, it is useful to understand exactly what was tried.
What Should Knee Arthritis Physiotherapy Include?
For knee osteoarthritis, rehabilitation should generally involve an active component.
Depending on the individual, this may include:
- Quadriceps strengthening
- Hip and gluteal strengthening
- Lower-limb strengthening
- Mobility work
- Functional exercise
- Sit-to-stand practice
- Step exercises
- Walking progression
- Aerobic activity
- Home exercises
- Progressive increases in difficulty
Passive treatments may sometimes be useful as adjuncts.
But knee arthritis rehabilitation should not necessarily consist only of:
Massage + machines + repeat.
Was the Exercise Programme Progressed?
This is another common issue.
Exercise that was challenging during week one may become easy after several weeks.
If the programme never changes, the stimulus may eventually become insufficient.
Progression can involve changing:
- Resistance
- Repetitions
- Sets
- Range of movement
- Exercise difficulty
- Walking duration
- Aerobic intensity
- Functional challenge
A rehabilitation programme should therefore evolve as the patient improves.
Did Pain Prevent Effective Rehabilitation?
Sometimes physiotherapy is appropriate, but pain prevents the patient from participating properly.
For example:
The patient is asked to strengthen.
But every exercise hurts significantly.
So the patient performs less.
Strength does not improve sufficiently.
Walking remains difficult.
This does not necessarily mean:
“Exercise doesn’t work.”
It may mean that pain needs to be managed sufficiently for rehabilitation to progress.
That can require medical reassessment.
Is Knee Osteoarthritis Really the Main Problem?
Persistent knee pain should not automatically be attributed to osteoarthritis simply because an X-ray shows arthritis.
Other problems can contribute to knee symptoms.
These may include:
- Meniscal problems
- Tendon disorders
- Patellofemoral pain
- Ligament injuries
- Gout
- Inflammatory arthritis
- Previous trauma
- Referred pain
- Other musculoskeletal conditions
If symptoms are not responding as expected, reconsidering the diagnosis can be important.
Do I Need Another X-Ray?
Not necessarily.
If recent imaging already answers the relevant clinical question, repeating it may add little.
But imaging may be appropriate when:
- The diagnosis remains uncertain
- Symptoms have changed significantly
- There has been a new injury
- The doctor needs additional information to guide treatment
Imaging should answer a question.
It should not simply be performed because treatment has not worked.
Do I Need an MRI?
Again:
Not automatically.
MRI is not routinely required simply because someone has knee osteoarthritis.
It may be useful when:
- Symptoms do not fit straightforward osteoarthritis
- Another condition is suspected
- The diagnosis remains uncertain
- Additional information would change management
The question should be:
“Will this MRI change what we do?”
rather than:
“Can I get an MRI?”
Should I Just Continue Physiotherapy?
Sometimes, yes.
If the patient is clearly improving but has not yet reached their goals, continued rehabilitation may be reasonable.
For example:
Before treatment:
Walking tolerance: 10 minutes
After treatment:
Walking tolerance: 25 minutes
The knee still hurts, but function is clearly improving.
That is different from:
Eight weeks of treatment with no meaningful change.
The decision should be based on progress.
Measure Function, Not Just Pain
Pain scores alone do not tell the entire story.
Ask:
Can I walk further?
Are stairs easier?
Can I get out of a chair more comfortably?
Am I exercising more?
Can I work more comfortably?
Am I sleeping better?
Can I go out with family and friends again?
Do I feel more confident using my knee?
These changes can represent meaningful improvement even if some pain remains.
What If There Has Been No Meaningful Improvement?
Then repeating exactly the same programme indefinitely may not be useful.
The next step should be to identify possible barriers.
These may include:
- Incorrect diagnosis
- Inadequate exercise progression
- Insufficient adherence
- Pain preventing exercise
- Significant weakness
- Excess body weight
- Other medical conditions
- Another knee problem
- More advanced functional limitation
Treatment can then be adjusted accordingly.
Could Weight Be Limiting My Progress?
For patients who are overweight, weight management may be an important part of knee osteoarthritis treatment.
This does not mean:
“Your knee hurts because you’re overweight.”
Knee pain is usually more complicated than that.
But excess body weight is one potentially modifiable factor.
The challenge is that knee pain may itself make weight management harder.
This creates a cycle:
Pain
↓
Less activity
↓
Reduced fitness
↓
Difficulty managing weight
↓
Greater difficulty moving
For appropriate patients, rehabilitation and weight management can therefore be addressed together.
Could Medication Help?
Sometimes.
Medication may help reduce symptoms sufficiently to allow:
- Walking
- Exercise
- Physiotherapy
- Better sleep
- Improved daily function
Singapore’s current knee osteoarthritis guidance includes topical anti-inflammatory medication as an option supporting the mainstay strategies, with short courses of oral anti-inflammatory medication considered for suitable patients when appropriate.
Medication should be individualised according to medical history and risk.
What About Shockwave Therapy?
Shockwave therapy is used for selected musculoskeletal conditions.
At The Pain Relief Clinic, shockwave may be considered as an adjunct in appropriate situations when basic rehabilitation alone has not been sufficient.
However:
Not every patient with knee osteoarthritis needs shockwave.
It should be used because there is a clinical reason—not simply because physiotherapy has not produced the desired result.
Active rehabilitation may still remain part of the treatment plan.
What About TECAR Therapy?
TECAR-based therapy may also be used as an adjunct to rehabilitation in selected patients.
At The Pain Relief Clinic, this may be incorporated into treatment where clinically appropriate.
Again, it should not replace:
- Exercise
- Strengthening
- Functional rehabilitation
- Appropriate medical assessment
The treatment machine should support the rehabilitation plan rather than become the rehabilitation plan.
Should I Consider a Steroid Injection?
Possibly.
Singapore’s current knee osteoarthritis guideline recommends considering an intra-articular corticosteroid injection for short-term symptom relief when symptoms persist despite appropriate medication and/or allied-health support.
This means steroid injection can have a role when first-line strategies have not been sufficient.
For an appropriate patient, reducing pain temporarily may make it easier to:
- Walk
- Exercise
- Participate in physiotherapy
- Perform everyday activities
But an injection does not strengthen the knee.
Rehabilitation may therefore remain important.
Does a Steroid Injection Cure Knee Arthritis?
No.
The purpose is generally symptom relief.
The duration and degree of benefit can vary between patients.
Potential benefits and risks should be discussed with the treating doctor.
What About Hyaluronic Acid or Viscosupplementation?
Hyaluronic acid injections are also known as:
Viscosupplementation.
They are offered by some clinics for knee osteoarthritis.
However, evidence and recommendations are less consistent than for core treatments such as exercise and weight management.
In Singapore, hyaluronic acid injections are not currently subsidised for knee osteoarthritis on the same basis as intra-articular corticosteroid injections, reflecting differences in the evidence considered for subsidy decisions.
That does not necessarily mean no patient can ever consider viscosupplementation.
It means it should not automatically be presented as a proven next step for everyone.
Patients should discuss:
- Potential benefit
- Limitations
- Risks
- Cost
- Alternatives
- Previous treatment response
before proceeding.
What About “Regenerative” Knee Injections?
Patients may encounter treatments marketed as:
- Regenerative injections
- Platelet-based treatments
- Biologic treatments
- Other injectable therapies
Claims can vary substantially.
Patients should ask:
What exactly is being injected?
What evidence supports it?
What outcome should I realistically expect?
What are the risks?
What does it cost?
What do current clinical guidelines say?
The more expensive a treatment is, the more important these questions become.
What About Pulsed Radiofrequency?
Some patients have persistent chronic knee pain despite appropriate conservative treatment.
For selected patients, advanced pain-management assessment may be appropriate.
At The Pain Relief Clinic, visiting specialist doctors can assess suitable patients for options including:
Pulsed radiofrequency
where clinically appropriate.
This is an escalation option rather than routine first-line treatment.
The purpose of advanced pain-management treatment may be to reduce pain and improve function in selected patients whose symptoms remain significant despite simpler measures.
Does Pain Treatment Replace Rehabilitation?
Usually, that should not be the assumption.
Imagine that a procedure reduces pain.
That can be valuable.
But if the patient remains:
- Weak
- Inactive
- Poorly conditioned
- Afraid to move
then an important part of the functional problem remains.
An effective strategy may therefore combine:
PAIN MANAGEMENT
with
REHABILITATION.
The aim is not simply:
“Make the knee hurt less.”
It is:
“Help the person function better.”
When Should I See an Orthopaedic Specialist?
Orthopaedic assessment may be appropriate when:
- Symptoms remain significant despite appropriate conservative treatment
- Walking is substantially limited
- Stairs are extremely difficult
- Sleep is repeatedly affected
- Work is significantly affected
- Daily activities are becoming difficult
- Quality of life is substantially impaired
- Surgery may reasonably need to be considered
Referral does not automatically mean surgery will occur.
It means obtaining an appropriate specialist assessment.
When Should Knee Replacement Be Considered?
Knee replacement can be highly relevant for appropriately selected patients with severe symptomatic knee osteoarthritis.
It should neither be:
Rushed into unnecessarily
nor
Avoided indefinitely when it is appropriate.
Singapore’s current clinical guidance supports surgical referral when persistent symptoms substantially affect function and quality of life despite appropriate management.
The decision should consider:
- Symptoms
- Function
- Imaging
- Previous treatment
- General health
- Patient preferences
“I Want to Avoid Surgery at All Costs”
It is understandable that some patients prefer to avoid surgery.
But the goal should not necessarily be:
Avoid surgery forever.
A better objective may be:
Use appropriate conservative treatment for as long as it provides sufficient function and quality of life.
If conservative treatment is working, continue it.
If it is no longer working and disability is substantial, specialist assessment may be appropriate.
A Practical Escalation Pathway
If basic physiotherapy has not been enough, a reasonable pathway may look like:
1. REASSESS
Is the diagnosis correct?
↓
2. REVIEW THE REHABILITATION
Was it active, appropriate and sufficiently progressed?
↓
3. ADDRESS BARRIERS
Pain, weight, weakness, adherence or other medical factors.
↓
4. OPTIMISE MEDICAL MANAGEMENT
Where appropriate.
↓
5. CONSIDER ADJUNCTIVE REHABILITATION
Such as selected shockwave or TECAR-based treatment where clinically appropriate.
↓
6. CONSIDER INJECTION OPTIONS
For appropriate patients after discussion of benefits, limitations and evidence.
↓
7. ADVANCED PAIN MANAGEMENT
For selected persistent cases.
↓
8. ORTHOPAEDIC ASSESSMENT
When significant functional limitation persists.
This is not a rigid ladder.
Individual patients may require different pathways.
Why Integrated Doctor + Physiotherapy Care Can Help
When physiotherapy and medical treatment occur completely separately, a patient can sometimes become stuck.
The physiotherapist says:
“You should ask your doctor.”
The doctor says:
“Continue physiotherapy.”
The patient remains uncertain about what happens next.
At The Pain Relief Clinic, our doctors work alongside our:
Experienced, AHPC-Registered Physiotherapists
within the same care pathway.
This allows the treatment cycle to become:
DOCTOR
↓
PHYSIOTHERAPIST
↓
REASSESS
↓
MODIFY OR ESCALATE
rather than continuing one treatment indefinitely.
Why AHPC Registration Matters
Physiotherapy is regulated in Singapore by the Allied Health Professions Council (AHPC).
Patients should verify that their physiotherapist is appropriately AHPC-registered and authorised to practise.
At The Pain Relief Clinic, our physiotherapy team consists of experienced, AHPC-registered physiotherapists.
This provides independently verifiable professional registration and supports an appropriately documented clinical pathway.
It can also be relevant when treatment documentation is required for eligible MediSave or insurance claims.
AHPC registration itself does not guarantee claimability.
What If My Previous Physiotherapy Was Somewhere Else?
That is not a problem.
You do not necessarily need to start everything again.
Where available, bring information such as:
- Previous X-rays
- MRI reports
- Medication lists
- Physiotherapy reports
- Previous exercise programmes
- Injection records
- Specialist letters
The objective is to understand what has already been tried and what should happen next.
Do I Have to Repeat Physiotherapy at The Pain Relief Clinic?
Not automatically.
The purpose of reassessment is to determine the appropriate next step.
That may involve:
- Modifying rehabilitation
- Continuing exercises independently
- Additional physiotherapy
- Medical treatment
- Weight management
- Additional investigation
- Injection treatment
- Advanced pain management
- Specialist referral
The recommendation should depend on the individual patient’s needs.

Frequently Asked Questions
What should I do if physiotherapy hasn’t helped my knee arthritis?
The next step should generally be reassessment.
Review the diagnosis, exercise programme, progression, pain control and other factors that may be preventing improvement.
Should I just do more physiotherapy?
Not automatically.
Continued physiotherapy may be appropriate if you are making meaningful progress.
If there has been little improvement, the treatment strategy should be reviewed.
Do I need an MRI if physiotherapy doesn’t work?
Not necessarily.
MRI is more useful when another diagnosis is suspected or the additional information is likely to change management.
Should I get a steroid injection?
It may be considered for short-term symptom relief in appropriate patients whose symptoms persist despite suitable medication and/or allied-health support.
It is not automatically required simply because physiotherapy has not helped enough.
Is hyaluronic acid injection better than steroid?
They are different treatments with different evidence, objectives and considerations.
There is no universal answer suitable for every patient.
Can shockwave help knee arthritis?
Shockwave may be considered as an adjunct in selected musculoskeletal situations, but it is not automatically required for every patient with knee osteoarthritis.
What about TECAR therapy?
TECAR-based treatment may be used as an adjunct in selected patients, but active exercise and rehabilitation remain important.
What is pulsed radiofrequency?
Pulsed radiofrequency is an interventional pain-management option that may be considered for selected patients with persistent chronic pain after appropriate assessment.
It is not routine first-line treatment for knee osteoarthritis.
When should I see an orthopaedic surgeon?
Specialist assessment may be appropriate when persistent symptoms significantly affect function and quality of life despite appropriate conservative treatment.
Does seeing a surgeon mean I need surgery?
No.
An orthopaedic consultation is an assessment.
Surgery is one possible treatment depending on the patient’s condition.
Are The Pain Relief Clinic’s physiotherapists AHPC-registered?
Yes.
Our physiotherapy team consists of experienced, AHPC-registered physiotherapists working alongside our doctors.
If Physiotherapy Isn’t Enough, Don’t Just Repeat It Forever
The important principle is:
PHYSIOTHERAPY
↓
MEASURE THE RESPONSE
↓
REASSESS
↓
IDENTIFY THE BARRIER
↓
MODIFY OR ESCALATE TREATMENT
The objective is not to keep a patient in physiotherapy indefinitely.
Nor is it to jump immediately to surgery.
It is to determine:
What is the next appropriate level of care?
From Rehabilitation to Specialist Treatment When Needed
At The Pain Relief Clinic, our knee arthritis pathway can include:
Doctor-Led Assessment
Experienced AHPC-Registered Physiotherapy
Exercise & Strengthening
Lifestyle & Weight Management
Appropriate Medication
Appropriate Imaging
Shockwave or TECAR-Based Adjunctive Treatment in Selected Cases
Corticosteroid Injection Where Appropriate
Viscosupplementation Where Appropriately Considered
Advanced Pain-Management Assessment
Pulsed Radiofrequency for Selected Patients
Visiting Specialist Doctors
Orthopaedic Referral When Necessary
The principle is simple:
Start with the simplest appropriate treatment.
Measure whether it works.
Escalate when necessary.

What To Expect When I Visit The Pain Relief Clinic
A typical visit will involve our doctor first understanding your medical history, concerns and previous experience with other pain treatments.
For patients who have consulted many people but have yet to receive a clear diagnosis, selecting an affordable imaging scan might be recommended to confirm the cause of your pain..
Some patients have already done scans with other doctors for their pain condition but are still not clearly told what they suffer from.
Dr Terence Tan is happy to offer you a second opinion and recommend how best to manage your condition.
We also see patients who already have a confirmed diagnosis from specialist pain doctors, but are "stuck” because treatment options offered are not practical or acceptable.
We can help by discussing options that you might have potentially never been told of.
A common experience is when a patient has already consulted a specialist doctor for pain management and is told to consider orthopaedic surgery which they find too aggressive.
Or they may have seen doctors for their pain and were prescribed painkillers with potential side effects which made them feel uncomfortable.
Many of our patients have also first tried complementary treatments or acupuncture with traditional Chinese pain doctors.
They look for a second opinion after finding any relief experienced from other treatments to be temporary or requiring repetitive treatments, which add up to time and cost.
Especially in such situations, we emphasize using non-invasive medical technology you likely have not been told about .
This can make a big difference to your results.
