Geniculate Artery Embolization (GAE) at Medex Diagnostic & Treatment Center in Queens offers a quick, same-day, minimally invasive solution for knee-arthritis pain: board-certified interventional radiologists use a tiny catheter to block overactive geniculate arteries, reducing inflammation and delivering up to 80 % pain relief without hospital admission, lengthy recovery, or compromising future knee-replacement options – all conveniently handled under one Forest Hills roof with on-site imaging, lab work, and insurance coordination.
Knee osteoarthritis (OA) is no longer just an “older adult” problem. In the United States alone, more than 14 million people live with symptomatic knee OA, and the total OA burden across all joints tops 32.5 million adults. oaaction.unc.edu Globally, the World Health Organization estimates that 528 million people suffer from osteoarthritis—an astonishing 113 % increase since 1990—with the knee being the single most affected joint. who.int As lifespans lengthen and obesity remains prevalent, demand for durable, minimally invasive pain solutions keeps rising.
Geniculate Artery Embolization (GAE) is a catheter-based, image-guided procedure that reduces knee-joint inflammation by selectively blocking tiny branches of the genicular arteries—the vessels that feed the synovium lining the knee. By starving hyper-vascular, inflamed tissue of its blood supply, GAE interrupts the biochemical cascade that drives pain and cartilage breakdown.
Originally pioneered in Japan in 2013, the technique quickly caught the attention of interventional radiologists (IRs) worldwide. Early clinical series showed rapid pain relief, and larger prospective trials now confirm its safety and durability.
Because no bone or cartilage is removed, the joint structure remains intact, and GAE does not preclude later arthroplasty if needed.
Contra-indications include severe bone-on-bone OA (grade 4), active infection, uncorrectable coagulopathy, or severe peripheral arterial disease.
At Medex Diagnostic & Treatment Center in Forest Hills, Queens, patients have direct access to each of these specialties under one roof, streamlining referrals and after-care. medexdtc.com
Study / Year | Patients | Follow-up | Key Findings |
---|---|---|---|
Meta-analysis 2025 | 1,162 | 12 mo | 78–92 % achieved clinically meaningful improvement (≥50 % pain reduction). sciencedirect.com |
SIR Multicenter 2024 | 234 | 24 mo | Durable relief in 71 %; no major adverse events. pubmed.ncbi.nlm.nih.gov |
Berlin RCT 2024 | 403 | 12 mo | 87 % QoL improvement; 0 % severe complications. thesun.co.uk |
Importantly, the overall technical success rate is 99.7 %, underscoring the procedure’s reproducibility.
GAE’s complication profile is mild: transient skin bruising (7 %), low-grade post-embolization syndrome (4 %), and self-limited calf paresthesia (<1 %). No deep-vein thrombosis or cartilage necrosis has been reported in major series.
Treatment | Incision? | Recovery | Typical Pain Reduction | Long-term Drawbacks |
---|---|---|---|---|
GAE | 2 mm puncture | 1-2 weeks | 50-80 % | May need repeat embolization after 3-5 yrs |
Corticosteroid injection | None | <24 h | 20-30 % (short-term) | Cartilage thinning with repeat use |
Hyaluronic acid | None | <24 h | Variable | Expensive; effect often <6 mo |
Arthroscopic debridement | 1 cm portals | 4-6 wks | Inconsistent | Procedure no longer recommended by AAOS |
Total Knee Arthroplasty | 8-10 cm | 3-6 mo | 90 % | Implant wear; revision risk |
Forest Hills residents no longer need to travel into Manhattan for cutting-edge IR care. Medex’s on-site angiography suite allows same-day GAE with conscious sedation. Board-certified interventional radiologists collaborate with Medex’s sports-medicine and physical-therapy teams to create a 360-degree recovery plan—so patients move from consultation to catheter lab to follow-up PT in a single location.
How long does the procedure take?
Actual embolization averages 45 minutes; total lab time is about 90 minutes.
Will my insurance cover GAE?
Most commercial insurers now pre-authorize GAE for knee OA refractory to conservative therapy. Our billing team submits documentation on your behalf.
Can I still get a knee replacement later?
Yes. Because GAE does not alter bone anatomy, it does not complicate future arthroplasty.
Is the radiation dose significant?
Fluoroscopy-time averages 11 minutes—comparable to a diagnostic coronary angiogram and within FDA safety guidelines.
Does GAE help hip or shoulder arthritis?
Currently, GAE is validated only for the knee, although trials are exploring embolization for other joints.
