Genicular Artery Embolisation (GAE) in Singapore
Minimally Invasive Treatment for Selected Knee Osteoarthritis Pain
Genicular artery embolisation (GAE) is the latest minimally invasive, image-guided procedure that targets selected blood vessels supplying the knee.
It may be considered for appropriately selected patients with persistent knee pain associated with osteoarthritis, particularly when symptoms continue despite conservative treatment. It is a novel minimally-invasive procedure providing immediate and long term pain relief for patients with osteoarthritis (OA), by reducing the blood flow to the lining of the knee, known as the synovium.
During GAE, a thin catheter is guided through the blood vessels towards selected genicular arteries. Small embolic particles are then delivered to targeted vessels to reduce abnormal blood flow associated with inflammation around the knee.
At the Supreme Vascular and Interventional Clinic, treatment planning focuses on understanding the cause and severity of your knee pain before determining whether GAE is appropriate.
Care is led by Dr. Manish Taneja, providing specialist image-guided and interventional expertise with a continuum of care under one roof.

What Is Genicular Artery Embolisation?
Genicular artery embolisation is a minimally invasive procedure designed to reduce abnormal blood flow in selected arteries around the knee.
In osteoarthritis, changes within the joint can be associated with inflammation and increased development of small blood vessels around the affected area. These vessels are known as abnormal neovessels.
GAE uses catheter-based angiography to identify selected genicular arteries associated with this abnormal vascular supply.
Small embolic particles are then delivered to carefully selected vessels to reduce the targeted blood flow.
The procedure aims to reduce the vascular contribution to inflammation and pain while preserving the major blood supply to the knee.

How Does Genicular Artery Embolisation Work?
Targeting Selected Blood Vessels Around the Knee
Your knee symptoms, medical history and previous treatments are first reviewed. Relevant knee imaging is assessed to understand the underlying joint condition.
A small catheter is introduced through an appropriate blood vessel usually through the groin area. The catheter is guided towards the arteries supplying the knee.
Angiography is performed to map the genicular arteries and identify the relevant vascular supply. Small embolic particles are delivered into selected target vessels.
The catheter is removed and the access site is monitored after treatment.


When Might GAE Be Considered?
GAE may be considered for selected patients with persistent knee osteoarthritis pain.
Your specialist may consider:
- Persistent knee pain
- Knee osteoarthritis confirmed through clinical assessment and imaging
- Symptoms that continue despite conservative treatment
- Pain that significantly affects daily activities
- Whether other non-surgical treatments have provided sufficient relief
- Your overall health and medical history
- Whether the vascular pattern around the knee is suitable for embolisation
While GAE may not appropriate for every patient with knee pain, it can be combined with other techniques such as intra-articular injections of steroids, N-stride injection or knee nerve blocks/ablation (genicular nerve block/ablation).
A detailed assessment is important to determine whether the procedure is suitable for your individual condition.
Genicular Artery Embolisation for Knee Osteoarthritis
A Minimally Invasive Approach to Persistent Knee Pain
Knee osteoarthritis can cause pain, stiffness and difficulty with everyday activities.
Conventional treatment may include exercise, physiotherapy, weight management, medication or injections depending on the individual's circumstances.
For selected patients whose symptoms remain troublesome despite these approaches, GAE provides another minimally invasive treatment option.
Rather than directly treating or replacing the damaged joint, GAE targets selected blood vessels around the knee.
This makes it different from surgical knee replacement and other treatments that directly address the joint itself.
Who May Be Suitable for GAE?
There is no single profile that determines whether GAE is appropriate.
Your specialist may consider the procedure when you have:
- Symptomatic knee osteoarthritis
- Persistent or significant knee pain
- Limited improvement with conservative treatment
- Imaging findings consistent with osteoarthritis
- A desire to explore minimally invasive treatment options
- Suitable vascular anatomy for embolisation
The decision should be based on a complete assessment rather than symptoms alone.
Potential Benefits of Genicular Artery Embolisation
A Minimally Invasive Option for Selected Patients
For appropriately selected patients, GAE may offer several potential benefits.
Minimally Invasive
GAE is performed through a small catheter rather than open knee surgery.
Targeted Treatment
The procedure focuses on selected arteries supplying the knee.
No Joint Replacement
GAE does not involve replacing the knee joint.
Image-Guided Precision
Angiography allows the specialist to identify and selectively treat the targeted vessels.
Potential Alternative to More Invasive Treatment
For selected patients, GAE may provide another option when conservative treatments have not provided adequate relief.
Individualised Treatment
Treatment is planned according to your symptoms, imaging findings, vascular anatomy and overall health
GAE vs Other Knee Pain Treatments
Understanding Your Options
Different treatments address different aspects of knee osteoarthritis and pain.
| Treatment | How It Works | Primary Approach |
|---|---|---|
| Genicular Artery Embolisation | Reduces selected abnormal blood flow around the knee | Minimally invasive vascular treatment |
| Physiotherapy | Improves strength, movement and function | Rehabilitation |
| Medication | Helps manage pain and inflammation | Symptom management |
| Joint Injection | Delivers medication into or around the joint | Symptom management |
| Knee Replacement | Replaces the damaged joint surfaces | Surgical treatment |
The most appropriate treatment depends on the severity of osteoarthritis, symptoms, previous treatment and individual circumstances.
Can GAE Replace Knee Replacement?
GAE and knee replacement are different treatments. GAE does not replace or repair the damaged knee joint.
Instead, it targets selected blood vessels around the knee and may be considered for appropriately selected patients with persistent osteoarthritis-related pain.
Whether GAE may help delay or avoid surgery for an individual patient cannot be determined without a specialist assessment.
What Are the Potential Risks and Considerations?
Understanding What to Expect
GAE is minimally invasive, but like any vascular procedure it has potential risks and considerations.
These may include:
- Temporary pain or discomfort
- Bruising at the catheter access site
- Temporary skin discolouration or changes
- Swelling
- Reaction to contrast material
- The possibility that pain may persist or require additional treatment
Your individual risks depend on your medical history, vascular anatomy and the specific treatment performed.
Your specialist will explain the expected benefits, potential risks and alternatives before treatment.
Recovery After Genicular Artery Embolisation
What Can You Expect?
Recovery is generally relatively short after an uncomplicated GAE procedure, although individual experiences vary. Done as a day surgery under light intravenous sedation, it takes about 45 minutes to complete the procedure. Both knees can be treated at same time. Patients are able to go resume their normal activities within a couple of days.
After treatment, you may be advised to:
- Rest for a short period
- Walk according to your specialist's instructions
- Keep the catheter access site clean and dry
- Avoid strenuous activity for the recommended period
- Take medication as prescribed
- Monitor the access site
- Attend follow-up appointments
Some patients may experience temporary knee discomfort or other local symptoms following treatment.
Your specialist will provide personalised recovery instructions based on your procedure and individual circumstances.
