If exercise, physiotherapy and medication have not provided enough relief from knee osteoarthritis, you may start looking for the next treatment.

Should you have a:

• Steroid injection?
• Hyaluronic acid injection?
• PRP injection?
• Ultrasound-guided injection?
• Pulsed radiofrequency procedure?
• Radiofrequency ablation?
• Specialist pain procedure?

And what about newer treatments described as “regenerative,” such as autologous protein solution?

The answer is not simply to choose the newest treatment.

Different procedures have different purposes, evidence, regulatory positions and appropriate uses.

At The Pain Relief Clinic, our approach is to start with the simplest appropriate treatment and escalate according to the patient’s response:

ASSESS → REHABILITATE → REASSESS → CONSIDER INJECTION OR ADVANCED PAIN TREATMENT → CONTINUE REHABILITATION → SPECIALIST / SURGICAL REFERRAL WHEN NECESSARY

Our doctors work alongside experienced, AHPC-registered physiotherapists.

For selected patients who require more advanced treatment, visiting accredited specialists can also assess and provide appropriate options including ultrasound-guided injections, pulsed radiofrequency and radiofrequency ablation.

What Do Singapore Guidelines Recommend for Knee Osteoarthritis?

Singapore’s 2026 clinical guideline for knee osteoarthritis recommends:

Education

Exercise

Weight management

as mainstay strategies for patients with knee osteoarthritis, individualised according to the patient.

The guideline also recommends considering allied-health support such as supervised exercise and physiotherapy.

For persistent symptoms, an intra-articular corticosteroid injection may be considered for short-term symptom relief alongside the mainstay strategies.

And importantly, for patients whose persistent symptoms significantly affect function and quality of life, the guideline recommends discussing referral for:

Surgical OR advanced pain management options.

This is important because knee osteoarthritis treatment does not end at physiotherapy or injections. Agency for Care Effectiveness

---

When Should an Injection Be Considered?

An injection does not automatically need to be the first treatment for knee osteoarthritis.

It may become relevant when symptoms remain troublesome despite an appropriate conservative programme.

For example:

A patient understands that strengthening is important.

But pain prevents meaningful exercise.

Or:

The patient has completed an appropriate rehabilitation programme but still has significant difficulty with:

• Walking
• Stairs
• Standing
• Exercise
• Work
• Sleep
• Travel
• Family activities

At that point, the question becomes:

What is preventing further improvement?

An injection or another interventional treatment may then form part of the treatment pathway.

---

Option 1: Corticosteroid Injection

Corticosteroid injection has an established role for selected patients with symptomatic knee osteoarthritis.

Singapore’s current guideline recommends considering:

Intra-Articular Corticosteroid Injection

for short-term symptom relief when symptoms persist despite appropriate NSAID treatment and/or allied-health support. Agency for Care Effectiveness

The important phrase is:

Short-term symptom relief.

Steroid injection does not reverse osteoarthritis.

---

What Can a Steroid Injection Help With?

For an appropriate patient, reducing pain may make it easier to:

• Walk
• Climb stairs
• Sleep
• Work
• Exercise
• Participate in physiotherapy
• Perform everyday activities

Responses vary between patients.

Some patients obtain useful relief.

Others may experience less benefit.

---

Injection + Rehabilitation

An injection does not necessarily replace physiotherapy.

Sometimes it can create an opportunity:

LESS PAIN

↓

BETTER MOVEMENT

↓

MORE EFFECTIVE REHABILITATION

↓

IMPROVED STRENGTH AND FUNCTION

If symptoms improve, that period can potentially be used to progress:

• Strengthening
• Walking
• Exercise
• Fitness
• Functional rehabilitation
• Weight management where appropriate

The objective should not simply be:

“Make the knee hurt less.”

It should be:

Help the person function better.

---

Option 2: Hyaluronic Acid / Viscosupplementation

Hyaluronic acid injection is also known as:

Viscosupplementation.

Hyaluronic acid is naturally present within joint fluid.

Viscosupplementation involves injecting a hyaluronic-acid preparation into the knee.

Some patients report symptomatic improvement.

However, scientific studies and international guidelines have not been completely consistent regarding the magnitude of benefit or which patients are most likely to benefit.

It should therefore be considered individually.

Factors may include:

• Severity of osteoarthritis
• Symptoms
• Previous treatment
• Previous injection response
• Medical history
• Expected benefit
• Risks
• Cost
• Patient preferences

---

Is Hyaluronic Acid Better Than Steroid?

There is no universal answer.

They are different treatments.

Corticosteroid injection has a specifically recognised role in Singapore’s current clinical guideline for short-term symptom relief in selected patients.

Hyaluronic acid has different evidence and considerations.

The more useful question is:

Which option is appropriate for this patient at this stage?

---

Option 3: Platelet-Rich Plasma — PRP

Platelet-rich plasma, commonly called:

PRP

is prepared from the patient’s own blood.

The blood is processed to produce a platelet-rich preparation which is then used as part of the treatment.

PRP has attracted considerable scientific interest for knee osteoarthritis.

Importantly:

The evidence continues to evolve.

---

What Does Current Evidence Say About PRP?

Research has reported improvements in pain and function following PRP in some patients with knee osteoarthritis.

However, studies differ considerably in:

• Patient selection
• Osteoarthritis severity
• PRP preparation
• Platelet concentration
• Leukocyte concentration
• Number of injections
• Treatment protocol
• Comparator treatment
• Follow-up duration

This helps explain why research findings and clinical recommendations have not always been identical.

The appropriate interpretation is neither:

“PRP doesn’t work.”

nor:

“PRP regenerates every arthritic knee.”

A more appropriate conclusion is:

PRP is an evolving treatment with evidence of potential symptomatic and functional benefit in selected patients, while important questions concerning patient selection and treatment protocols continue to be studied.

---

Singapore’s Position on PRP Is Evolving Too

The Singapore Ministry of Health has specifically been examining PRP for low-grade knee osteoarthritis.

In a July 2026 circular, MOH described a proposed 36-month assessment of the clinical efficacy of PRP for low-grade knee osteoarthritis, defined as Kellgren-Lawrence grades 1 or 2.

This is important.

It does not amount to saying:

“PRP is now established treatment for everybody with knee arthritis.”

Instead, it demonstrates that PRP is an area of active clinical evaluation in Singapore.

Any treatment must follow prevailing Singapore regulatory and professional requirements.

---

Does PRP Regrow Cartilage?

Patients should be cautious about claims suggesting that PRP reliably restores an arthritic knee to its original condition.

Most clinically relevant research examines outcomes such as:

• Pain
• Function
• Walking
• Patient-reported improvement

rather than demonstrating complete restoration of damaged cartilage.

The term:

“Regenerative”

should therefore not be interpreted as a guarantee of cartilage regrowth.

---

What About Autologous Protein Solution — APS?

Another blood-derived treatment patients may encounter online is:

Autologous Protein Solution

or:

APS.

APS should not simply be grouped together with PRP.

They are different treatments.

And importantly, their current regulatory positions in Singapore are different.

---

What Is Singapore’s Current Position on APS for Knee Osteoarthritis?

The July 2026 MOH circular specifically identifies:

Autologous Protein Solution for knee osteoarthritis

as a Non-Evidence Based Medical Treatment under the proposed modified licence conditions.

MOH states that there is currently insufficient consistent evidence in published literature to support APS for knee osteoarthritis as a mainstream clinical service.

This provides an important lesson for patients:

“Biological” does not automatically mean “evidence-based.”

And:

“Autologous” does not automatically mean “proven.”

PRP and APS should not be assumed to have the same evidence or regulatory position.

---

Why This Distinction Matters

Patients may encounter terms such as:

• Regenerative medicine
• Biological treatment
• Autologous treatment
• Protein therapy
• Platelet treatment

These terms can sound similar.

But the treatments may be very different.

Before considering any biological treatment, ask:

What exactly is being injected?

What evidence supports it?

What does Singapore’s current regulatory framework say?

What outcome should I realistically expect?

What are the uncertainties?

What alternatives are available?

This is more useful than simply asking:

“Is it regenerative?”

---

Can Knee Injections Be Ultrasound-Guided?

Yes.

Some knee injections and interventional procedures can be performed using:

Ultrasound Guidance.

Instead of relying solely on surface anatomical landmarks, ultrasound allows the doctor or specialist to visualise relevant anatomy and needle placement in real time.

---

What Are the Advantages of Ultrasound-Guided Knee Injection?

One of the clearest advantages is:

Accuracy.

A recent systematic review reported cumulative accuracy of approximately:

95.4% with ultrasound guidance

versus:

82.0% with landmark guidance

for intra-articular knee injections and aspirations. PubMed

Randomised-trial evidence has also found improvements favouring ultrasound guidance for procedural pain, follow-up pain and function in knee OA. PubMed

---

Other Potential Advantages of Ultrasound Guidance

Depending on the procedure and clinical situation, ultrasound can help with:

Real-Time Visualisation

The specialist can see relevant anatomy during the procedure.

Needle Placement

The needle can be visualised relative to the intended target.

Identifying Joint Fluid

Ultrasound can help identify an effusion.

Aspiration

Where aspiration is appropriate, imaging can assist needle placement.

Planning the Needle Path

Relevant surrounding structures can be considered during the procedure.

---

Does Every Knee Injection Need Ultrasound?

No.

Certain knee injections can be performed accurately using anatomical landmarks by experienced clinicians.

Ultrasound guidance is not automatically necessary for every procedure.

Its usefulness depends on:

• The procedure
• Anatomical target
• Patient anatomy
• Presence of fluid
• Previous procedures
• Clinical circumstances
• Specialist judgement

The useful question is:

“Would ultrasound guidance provide an advantage for my particular procedure?”

---

Ultrasound Guidance Does Not Make an Inappropriate Treatment Appropriate

This distinction is important.

Ultrasound can improve procedural precision.

But there are actually two separate questions:

1. Is this treatment appropriate?

and:

2. If it is appropriate, would ultrasound guidance improve the procedure?

Both need to be considered.

---

Ultrasound-Guided Procedures at The Pain Relief Clinic

For selected patients, visiting accredited specialists at The Pain Relief Clinic can provide ultrasound-guided injection and interventional treatment options where clinically appropriate.

This allows treatment to progress within a coordinated pathway:

DOCTOR ASSESSMENT

ULTRASOUND-GUIDED OR OTHER INTERVENTIONAL TREATMENT WHEN APPROPRIATE

---

What If the Problem Is Persistent Chronic Knee Pain?

This is where another category of treatment becomes relevant.

Not every procedure for knee osteoarthritis involves injecting medicine into the joint.

For selected patients with persistent chronic knee pain, treatment may instead target nerves involved in carrying pain signals from the knee.

This brings us to:

Radiofrequency Treatment.

---

What Is Radiofrequency Treatment for Knee Arthritis?

Radiofrequency procedures use specialised equipment to deliver radiofrequency energy to selected nerve targets associated with knee pain.

Patients may encounter terms such as:

Pulsed Radiofrequency — PRF

and:

Radiofrequency Ablation — RFA.

For knee osteoarthritis, treatment may involve selected:

Genicular nerves.

These procedures are different from injecting steroid or hyaluronic acid into the knee joint.

---

What Are Genicular Nerves?

Genicular nerves are nerve branches around the knee involved in sensory signalling, including pain.

For selected patients with persistent knee osteoarthritis pain, a specialist may consider whether targeting appropriate genicular nerve branches could help reduce pain.

The objective is generally:

Reduce pain signalling.

It is not:

Regrow cartilage.

---

What Is Pulsed Radiofrequency?

Pulsed radiofrequency uses radiofrequency energy delivered in pulses to selected pain-related nerve targets.

It is an:

Interventional pain-management procedure.

Research has evaluated pulsed radiofrequency for chronic knee osteoarthritis pain, with systematic-review evidence reporting reductions in pain following genicular nerve-targeted pulsed RF techniques. PubMed

It should be considered:

A specialist option for appropriately selected persistent knee pain

rather than routine first-line treatment for every patient with osteoarthritis.

---

What Is Radiofrequency Ablation?

Radiofrequency ablation, often called:

RFA

uses radiofrequency energy to affect selected pain-transmitting nerves.

For chronic knee osteoarthritis pain, this can involve selected:

Genicular nerve branches.

Unlike an intra-articular injection, the objective is not primarily to put medication into the arthritic joint.

Instead, the procedure aims to reduce pain transmission.

---

What Does the Evidence Say About RFA?

The evidence base for genicular nerve radiofrequency ablation has developed substantially.

A 2026 systematic review involving 28 studies and more than 2,200 patients reported meaningful pain reduction in patients with osteoarthritis, although outcomes varied according to technique. PubMed

More recent systematic-review and network meta-analysis evidence has also found genicular nerve RFA effective for chronic knee pain, with benefit demonstrated over multiple follow-up periods. PubMed

Sham-controlled trial evidence also supports clinically meaningful improvements in pain and function while noting heterogeneity between techniques and limitations in longer-term evidence. PubMed

This makes radiofrequency an important advanced pain-management option to understand.

---

Pulsed Radiofrequency vs Radiofrequency Ablation

Patients sometimes use these terms interchangeably.

They are not necessarily the same procedure.

Broadly:

Pulsed Radiofrequency

uses pulsed delivery of radiofrequency energy.

Radiofrequency Ablation

uses an ablative radiofrequency technique to affect pain-transmitting nerve function.

Different techniques may also exist within these categories.

The appropriate procedure depends on:

• Pain characteristics
• Target nerves
• Previous treatment
• Patient factors
• Specialist assessment
• Current evidence
• Clinical judgement

---

Are Radiofrequency Procedures “Injections”?

Patients sometimes call them injections because needles are used during the procedure.

However, it is more accurate to describe them as:

Interventional Pain Procedures.

The objective is different from injecting medication directly into the knee joint.

Patients researching treatment may nevertheless encounter search terms such as:

• Knee nerve injection
• Genicular nerve treatment
• Knee nerve block
• Pulsed radiofrequency knee
• Radiofrequency ablation knee
• RFA for knee arthritis
• Genicular nerve ablation

These terms can refer to different procedures.

---

Can Radiofrequency Treatment Be Ultrasound-Guided?

Ultrasound can be used to guide selected interventional procedures.

The appropriate imaging method depends on the particular procedure, target and specialist’s technique.

At The Pain Relief Clinic, selected patients can be assessed by our visiting accredited specialists for:

Ultrasound-Guided Interventional Treatment

where clinically appropriate.

---

Who Might Be Considered for Radiofrequency Treatment?

Radiofrequency treatment is not intended for everyone with knee osteoarthritis.

It may be considered in selected patients with persistent significant pain despite appropriate conservative management.

For example, pain may continue to interfere substantially with:

• Walking
• Stairs
• Work
• Sleep
• Exercise
• Physiotherapy
• Travel
• Everyday activities

The specialist must determine whether the patient’s clinical situation and pain pattern are appropriate for the procedure.

---

Does RFA Cure Knee Osteoarthritis?

No.

This distinction is extremely important.

Radiofrequency treatment can target:

PAIN.

It does not reverse:

STRUCTURAL OSTEOARTHRITIS.

The patient still has the underlying joint condition.

---

Does Radiofrequency Replace Physiotherapy?

Not necessarily.

Reducing pain does not automatically restore:

• Muscle strength
• Fitness
• Mobility
• Balance
• Confidence
• Functional capacity

If pain is successfully reduced, the patient may actually become better able to participate in rehabilitation.

A useful strategy may therefore be:

PAIN MANAGEMENT + REHABILITATION

rather than:

PAIN MANAGEMENT INSTEAD OF REHABILITATION.

---

Can Radiofrequency Help Me Avoid Knee Replacement?

It may provide symptom relief for appropriately selected patients.

But it should not be advertised as a guaranteed way to avoid knee replacement.

If severe osteoarthritis continues to cause major functional impairment despite appropriate treatment, orthopaedic assessment may still be the appropriate next step.

---

When Should I See an Interventional Pain Specialist?

Specialist assessment may be appropriate when:

• Knee pain remains significant despite appropriate conservative treatment
• Pain prevents effective rehabilitation
• Medication has not provided sufficient relief or is unsuitable
• Previous treatment has provided inadequate benefit
• The patient wants to understand advanced non-surgical pain-management options

At The Pain Relief Clinic, selected patients can be assessed by our:

Visiting Accredited Specialists

for appropriate options including:

Ultrasound-Guided Injections

Specialist Injection Procedures

Pulsed Radiofrequency

Radiofrequency Ablation

Other Appropriate Interventional Pain-Management Procedures

where clinically indicated.

---

What If None of These Treatments Is Enough?

Then the answer should not necessarily be:

“Try another procedure.”

Reassessment matters.

If persistent symptoms substantially affect:

• Walking
• Work
• Sleep
• Independence
• Exercise
• Daily activities
• Quality of life

orthopaedic assessment may become appropriate.

Singapore’s current knee OA guideline specifically recognises referral for surgical or advanced pain management when persistent symptoms significantly affect function and quality of life. Agency for Care Effectiveness

---

Injection vs RFA vs Surgery: Which Is Best?

There is no universal winner.

These treatments operate at different levels.

For example:

Corticosteroid injection

may provide short-term symptom relief.

Hyaluronic acid

may be considered in selected circumstances after discussion of its evidence and limitations.

PRP

is an evolving biological treatment being actively studied for selected knee OA populations.

Pulsed radiofrequency / RFA

target pain signalling rather than the joint cartilage itself.

Knee replacement

addresses advanced structural joint disease in appropriately selected patients.

The better question is:

“Which level of treatment is appropriate for me now?”

---

The Pain Relief Clinic Knee Arthritis Treatment Pathway

At The Pain Relief Clinic, knee osteoarthritis treatment can progress through different levels.

LEVEL 1 — DOCTOR ASSESSMENT

Understand the diagnosis, symptoms and functional limitations.

↓

LEVEL 2 — PHYSIOTHERAPY

Work with our experienced, AHPC-registered physiotherapists.

↓

LEVEL 3 — EXERCISE & STRENGTHENING

Build an individualised rehabilitation programme.

↓

LEVEL 4 — WEIGHT & LIFESTYLE MANAGEMENT

Where appropriate.

↓

LEVEL 5 — REASSESS

Determine whether meaningful improvement has occurred.

↓

LEVEL 6 — APPROPRIATE INJECTION OPTIONS

Depending on the patient, evidence and prevailing Singapore requirements.

↓

LEVEL 7 — VISITING ACCREDITED SPECIALIST ASSESSMENT

For selected patients requiring more advanced treatment.

↓

LEVEL 8 — ADVANCED INTERVENTIONAL PAIN MANAGEMENT

Potentially including ultrasound-guided procedures, pulsed radiofrequency or radiofrequency ablation where clinically appropriate.

↓

LEVEL 9 — ORTHOPAEDIC ASSESSMENT

When persistent symptoms substantially affect function and quality of life despite appropriate treatment.

---

Why an Integrated Treatment Pathway Matters

The advantage of having different treatment levels available is not that every patient receives more procedures.

It is that treatment can escalate when necessary.

One patient may only require:

Education + exercise.

Another may require:

Doctor + physiotherapy.

Another may benefit from:

Injection + rehabilitation.

A smaller group may require:

Specialist interventional pain management.

And some patients may ultimately be better treated with:

Knee replacement surgery.

The objective should be:

The least invasive appropriate treatment that provides sufficient function and quality of life.

Frequently Asked Questions

What injections are available for knee arthritis in Singapore?

Options patients may encounter include corticosteroid injections, hyaluronic acid or viscosupplementation and, in appropriately selected circumstances and within prevailing Singapore requirements, PRP.

Different treatments have different evidence and appropriate uses.

---

Which knee injection is best?

There is no single injection that is best for everyone.

The appropriate option depends on the diagnosis, severity of osteoarthritis, symptoms, previous treatment, medical history, evidence, risks and patient’s goals.

---

Can knee injections be ultrasound-guided?

Yes.

Ultrasound can provide real-time guidance for selected knee injections.

Research has demonstrated greater accuracy for ultrasound-guided intra-articular knee injections compared with landmark-guided procedures. PubMed

---

Does The Pain Relief Clinic provide ultrasound-guided knee injections?

Selected patients can be assessed by our visiting accredited specialists for ultrasound-guided injection procedures where clinically appropriate.

---

Is PRP used for knee osteoarthritis?

PRP is an evolving area of knee osteoarthritis treatment.

Scientific evidence continues to develop, and Singapore is actively evaluating its role in selected patients with low-grade knee osteoarthritis.

Any use needs to comply with prevailing Singapore requirements.

---

Does PRP regrow cartilage?

Patients should not assume that PRP reliably regrows lost cartilage.

Research more commonly evaluates outcomes such as pain and function.

---

What is APS?

APS stands for Autologous Protein Solution.

It is a blood-derived treatment but should not be confused with PRP.

Singapore’s current regulatory position treats APS for knee osteoarthritis differently from PRP, and MOH has cited insufficient consistent evidence to support APS as a mainstream clinical service.

---

What is pulsed radiofrequency for knee pain?

Pulsed radiofrequency is an interventional pain-management technique involving radiofrequency energy delivered to selected pain-related nerve targets.

It may be considered for selected patients with persistent chronic knee pain.

---

What is radiofrequency ablation for knee arthritis?

Radiofrequency ablation targets selected pain-transmitting nerves around the knee, often involving genicular nerve branches.

Its purpose is pain reduction rather than cartilage restoration.

---

Does The Pain Relief Clinic offer pulsed radiofrequency and radiofrequency ablation?

Selected patients can be assessed by our visiting accredited specialists for interventional pain-management options including pulsed radiofrequency and radiofrequency ablation where clinically appropriate.

---

Is RFA better than steroid injection?

They are different treatments with different objectives and appropriate uses.

The appropriate treatment depends on the patient’s clinical situation rather than one treatment being universally superior.

---

Does RFA cure knee arthritis?

No.

RFA is a pain-management procedure and does not reverse structural osteoarthritis.

---

Can I still do physiotherapy after an injection or RFA?

Yes, where clinically appropriate.

Reducing pain may sometimes make strengthening and rehabilitation easier.

---

When should I consider knee replacement?

Orthopaedic assessment may be appropriate when persistent knee osteoarthritis symptoms significantly affect function and quality of life despite appropriate conservative treatment.

---

Before Choosing an Injection or Procedure, Ask These Questions

What exactly is being done?

What problem is this treatment intended to solve?

What evidence supports it?

Is it appropriate for my stage of knee osteoarthritis?

What improvement should I realistically expect?

How long might the benefit last?

What are the risks?

What are the alternatives?

Would ultrasound guidance provide an advantage?

Will I still need rehabilitation afterwards?

Does the treatment comply with prevailing Singapore requirements?

What happens if it doesn’t work?

These questions are more useful than simply asking:

“What’s the newest treatment?”

---

Evidence Changes. Good Clinical Principles Shouldn’t.

Knee osteoarthritis treatment continues to evolve.

New research may change how treatments such as PRP, image-guided procedures and radiofrequency interventions are used.

At The Pain Relief Clinic, our approach is to combine:

Current Singapore clinical and regulatory guidance

with:

Awareness of developing medical and scientific evidence.

That means neither adopting every new treatment simply because it is new nor dismissing useful treatments when stronger evidence develops.

The foundation remains:

ASSESSMENT + EXERCISE + REHABILITATION + WEIGHT MANAGEMENT WHERE APPROPRIATE.

Additional treatment can then be considered according to:

The patient + the evidence + disease severity + previous treatment + prevailing Singapore requirements.

For selected patients who need more advanced treatment, our visiting accredited specialists provide access to appropriate injection and interventional pain-management options, including ultrasound-guided procedures, pulsed radiofrequency and radiofrequency ablation.
