You have tried pain medicines, physiotherapy and perhaps injections, but your knee still hurts when you walk, climb stairs or stand for long periods. The next conversation often becomes uncomfortable: “Is knee replacement my only option now?”
Not always.
For carefully selected patients with knee osteoarthritis, Genicular Artery Embolization (GAE) is a minimally invasive treatment that may help reduce knee pain. It is performed by an interventional radiologist using imaging guidance to reach small blood vessels around the knee.
GAE is not suitable for everyone, and it should not be promoted as a guaranteed alternative to surgery. But for the right patient, it may be worth discussing.
From our experience working with patients and healthcare clients, the most useful consultation is one that explains both the possibilities and the limitations of newer treatments.
The genicular arteries are small blood vessels around the knee.
In some people with osteoarthritis, abnormal blood-vessel growth and inflammation around the joint may contribute to persistent pain. GAE aims to reduce blood flow through selected abnormal vessels using tiny embolic particles.
The procedure is performed through a small catheter rather than a large surgical incision.
An interventional radiologist first accesses an artery, commonly through the groin or wrist area, depending on the technique used.
Using X-ray imaging, the catheter is guided toward the blood vessels supplying the knee. Once the target vessels are identified, the doctor delivers an embolic material to reduce the abnormal blood flow.
The exact technique varies between patients and centres.
GAE is generally considered for selected people with symptomatic knee osteoarthritis, particularly when pain remains troublesome despite appropriate conservative treatment.
A doctor may consider factors such as:
Severity of knee osteoarthritis
Location and pattern of pain
Previous treatments
Response to medicines or injections
Imaging findings
Overall medical condition
Whether surgery is appropriate or being considered
This is why searching for Genicular Artery Embolization in Naraina should ideally lead to a specialist consultation rather than an automatic decision to undergo the procedure.
Imagine someone with chronic knee arthritis who has already tried physiotherapy, exercise, medicines and other conservative approaches.
The person still struggles to walk comfortably but is either not ready for knee replacement or may not currently be an ideal surgical candidate.
In such a situation, an interventional radiologist can review the case and determine whether GAE deserves consideration.
The goal is not simply to avoid surgery. It is to determine whether there is an appropriate minimally invasive option for that particular patient.
GAE is promising, but the evidence needs to be understood honestly.
A 2024 systematic review and meta-analysis covering 21 studies, 633 patients and 758 treated knees reported substantial average reductions in pain scores at 1, 3, 6 and 12 months after GAE. However, many studies included in the analysis were not controlled trials, which makes it harder to separate the treatment effect from other factors.
A 2024 randomised controlled trial comparing GAE with a sham procedure, however, did not find a significant difference in its primary outcome at four months.
More recently, a 2025 systematic review of three sham-controlled trials involving 138 patients found that GAE may provide short-term pain relief in selected patients, but concluded that stronger evidence is still needed.
That is an important message for patients: promising does not mean proven for everyone.
This is where we would challenge common advice.
Many patients search specifically for a treatment that will help them “avoid knee replacement.”
That is understandable, but it can lead to the wrong decision.
The goal should not be avoiding surgery. The goal should be choosing the treatment that gives you the best balance of benefit, safety and long-term function.
If your knee is severely damaged and surgery is the appropriate option, delaying it simply because GAE sounds less invasive may not be beneficial.
On the other hand, if your symptoms and medical history make you a reasonable candidate for GAE, discussing it before surgery can be sensible.
GAE has several features that make it attractive to appropriately selected patients.
It is minimally invasive, uses image guidance and generally requires only a small access point rather than a large surgical incision.
Some studies have reported meaningful improvements in pain and function following treatment. A 2025 meta-analysis involving 14 studies and 510 patients reported approximately a 30-point reduction on a 0–100 pain scale in pooled pre-to-post analyses at 6–12 months. However, these results largely came from studies without sham controls, so they should not be interpreted as proof of a guaranteed treatment effect.
GAE is still a medical procedure.
Potential complications can include bruising or bleeding at the catheter site, temporary skin changes, infection, damage to nearby blood vessels and other procedure-specific complications.
The choice of embolic material and the exact technique can also matter.
This is another reason to have a detailed discussion with an experienced interventional radiologist rather than treating GAE as a simple injection.
A proper consultation should begin with your knee—not the procedure.
Your doctor may review X-rays, MRI scans or other imaging, discuss your pain history and ask what treatments you have already tried.
You should also discuss whether your arthritis is mild, moderate or advanced and whether there are other causes contributing to your symptoms.
Before agreeing to GAE, ask:
Am I actually a suitable candidate?
What is causing my knee pain?
What other treatments should I consider?
What are the expected benefits in my case?
What are the procedure-specific risks?
Could I still need knee replacement later?
How long might recovery take?
A good consultation should make you feel informed—not pressured.
Consider a patient in their early 60s with persistent knee osteoarthritis who has difficulty walking and has already tried several conservative treatments.
Instead of assuming that the next step must immediately be knee replacement, the patient undergoes an interventional radiology assessment. Their imaging, symptoms and treatment history are reviewed.
If the patient appears suitable, GAE can be discussed as one option. If the assessment suggests that surgery or another treatment would be more appropriate, that should be explained just as clearly.
That is the approach we believe patients deserve: the right treatment, not simply the newest treatment.
Dr Raghav Seth, Interventional Radiologist, focuses on image-guided minimally invasive procedures and patient-specific treatment planning. For patients considering GAE, the priority should be a careful evaluation of the knee, discussion of realistic expectations and a clear explanation of whether the procedure is appropriate.
Consider speaking with an interventional radiologist if persistent knee osteoarthritis is affecting your walking, sleep, work or everyday activities despite appropriate conservative treatment.
You should also consider a specialist assessment if you have been told that surgery may eventually be necessary and want to understand whether other options are medically reasonable.
However, do not wait for your knee to become severely disabling before seeking advice.
Early assessment gives you more opportunity to understand the available treatment pathway.
Not necessarily. GAE may be considered for selected patients, but it is not a guaranteed replacement for knee replacement. The appropriate treatment depends on the severity of arthritis and the individual patient's condition.
The procedure time varies depending on the patient's anatomy, number of vessels treated and technique used. Your interventional radiologist should explain the expected procedure and recovery time before treatment.
Available studies suggest that GAE can be performed safely in appropriately selected patients, but it is not risk-free. Minor complications have been reported, and the long-term evidence is still developing.
If knee arthritis is making ordinary activities difficult and conventional treatments have not provided enough relief, don't assume that your only choices are continued pain or immediate surgery.
Book a consultation with Dr Raghav Seth, Interventional Radiologist, bring your latest scans and previous treatment records, and ask whether Genicular Artery Embolization in Naraina is genuinely suitable for your knee.
