Rutgers University–Camden Introduces Genicular Artery Embolization for Knee Pain Treatment
Understanding Genicular Artery Embolization
Genicular artery embolization (GAE) is a minimally invasive image‑guided procedure that targets the small blood vessels supplying the inflamed tissues around the knee. By blocking these vessels, the technique reduces the inflammatory cascade that drives pain in osteoarthritis, offering relief without the need for joint replacement or extensive surgery.
What Is the Procedure?
During GAE a thin catheter—roughly the width of a spaghetti strand—is inserted through a small puncture in the skin. Under real‑time fluoroscopy, the interventional radiologist navigates the catheter to the genicular arteries that feed the knee joint. Once positioned, a biodegradable embolic agent is injected, occluding the vessels and cutting off the excess blood flow that fuels inflammation.
How It Differs From Traditional Treatments
- Non‑surgical – No incisions, implants, or hospital stay.
- Targeted – Focuses on the source of inflammation rather than masking pain.
- Bridges the gap between conservative care (medication, injections) and knee replacement.
Who Can Benefit?
Ideal Candidates
GAE is most effective for adults with moderate to severe knee osteoarthritis who:
- Have persistent pain despite oral medications or corticosteroid injections.
- Are not yet ready for or cannot undergo total knee arthroplasty.
- Seek a quick recovery and return to daily activities.
Contraindications
Patients with active infection, severe peripheral vascular disease, or certain clotting disorders may not be suitable for the procedure. A thorough pre‑procedure evaluation will identify any risks.
The Procedure Process
Preparation
Before the day of the procedure, patients receive a detailed briefing, including:
- Review of medical history and current medications.
- Blood work to assess clotting function.
- Imaging studies (MRI or CT) to map the genicular arteries.
Step‑by‑Step
- Local anesthesia is administered at the puncture site.
- The catheter is guided to the target arteries under fluoroscopy.
- Embolic material is injected, occluding the vessels.
- The catheter is removed, and a small dressing is applied.
Recovery and Follow‑Up
Patients typically leave the clinic the same day. Key points for recovery include:
- Rest the knee for 24–48 hours.
- Resume light activities as tolerated.
- Attend a follow‑up visit within 2–4 weeks to assess pain relief and imaging.
Outcomes and Evidence
Pain Relief and Mobility Gains
Clinical studies report a 50–70% reduction in pain scores within 3 months of GAE, with many patients reporting improved walking distance and stair climbing ability.
Long‑Term Benefits
Because the procedure addresses the underlying inflammation, patients often experience sustained relief for 12–18 months, delaying or eliminating the need for knee replacement.
Choosing Rutgers University–Camden for Your Care
Expertise of the Interventional Radiology Team
Rutgers New Jersey Medical School’s interventional radiologists are nationally recognized for pioneering image‑guided therapies. Their daily practice of complex vascular procedures translates into precision and safety for GAE patients.
Advanced Imaging and Technology
University Hospital houses state‑of‑the‑art angiography suites that provide high‑resolution, real‑time imaging—critical for accurate catheter placement and embolic delivery.
Multidisciplinary Support
Patients receive coordinated care from orthopedists, pain specialists, and physical therapists, ensuring a comprehensive approach to joint health and functional recovery.
Next Steps for Patients
Consultation and Evaluation
Begin by scheduling an initial assessment with a Rutgers Health provider. During this visit, your medical history, imaging, and current pain levels will be reviewed to determine eligibility for GAE.
Insurance and Cost Considerations
Most major insurers cover GAE as a medically necessary procedure for qualifying osteoarthritis patients. Rutgers Health’s billing team can assist with pre‑authorization and explain out‑of‑pocket costs.
Preparing for Your Appointment
- Avoid blood thinners 48 hours before the procedure unless otherwise instructed.
- Bring a list of current medications and recent imaging studies.
- Plan for a caregiver or friend to accompany you if you have mobility concerns.
Frequently Asked Questions
Safety and Risks
Complications are rare but can include infection, bleeding, or non‑target embolization. The low‑risk profile is a major advantage over surgical options.
How Many Sessions Are Needed?
Most patients require a single session. However, a second session may be considered if pain persists beyond 6 months.
Can I Return to Sports?
Many patients resume low‑impact activities within 2–4 weeks. High‑impact sports may be delayed until pain is well controlled and the knee has regained strength.
Conclusion
Genicular artery embolization offers a promising, minimally invasive alternative for patients with chronic knee pain who have exhausted conservative measures but are not ready for joint replacement. Rutgers University–Camden’s expertise, advanced imaging, and multidisciplinary care make it an ideal destination for those seeking lasting relief.
