For many patients living with knee osteoarthritis, the prospect of knee replacement surgery can feel overwhelming — or simply may not be an option. At Surgical Specialists of Ocala, we are proud to offer these patients a new path forward through a clinical trial of Genicular Artery Embolization (GAE), a cutting-edge minimally invasive procedure that is changing the way we approach knee pain management.
What Is Genicular Artery Embolization?
Genicular Artery Embolization is an interventional radiology procedure that targets the small blood vessels surrounding the knee joint. In patients with osteoarthritis (OA), these genicular arteries can become abnormally enlarged, feeding the inflammatory tissue that lines the joint and driving the cycle of pain and degeneration. GAE works by introducing tiny microspheres through a thin catheter to selectively block these hypervascular vessels, disrupting the inflammatory process at its source.
Unlike intra-articular injections or nerve ablations, which primarily address pain signals, GAE intervenes at the vascular level — addressing a root contributor to the disease process itself. The procedure is performed under imaging guidance, requires no general anesthesia, and typically allows patients to return home the same day.
Who Is a Candidate for GAE?
GAE is specifically designed for patients who are not ideal candidates for total knee arthroplasty (TKA) — whether due to age, overall health status, medical comorbidities, or personal preference. It is also a valuable option for those seeking to delay surgical intervention while maintaining or improving their quality of life. As the prevalence of knee OA and obesity continues to rise across the United States, the demand for effective, non-surgical alternatives has never been greater.
Good candidates for GAE typically include patients with moderate to severe knee osteoarthritis who have not found adequate relief from conservative therapies such as physical therapy, oral medications, or joint injections, but who are not yet ready — or eligible — for joint replacement.
What Does the Research Show?
The clinical evidence supporting GAE is growing rapidly. Early research has demonstrated meaningful reductions in pain and improvements in mobility following the procedure, with benefits that have been sustained for up to two years post-embolization. Multiple randomized controlled trials are currently underway to further evaluate GAE’s safety and long-term efficacy, and the medical community anticipates more robust outcome data in the near future.
What sets GAE apart from many other OA treatments is its mechanism: by selectively targeting the abnormal vascularity that fuels joint inflammation, it addresses a fundamental driver of pain rather than masking symptoms alone. This positions GAE as a distinct and complementary tool within the broader continuum of osteoarthritis care.
Participating in the Clinical Trial at Surgical Specialists of Ocala
Surgical Specialists of Ocala is actively enrolling patients in a clinical trial evaluating GAE for the treatment of knee osteoarthritis. Participation in this trial offers eligible patients access to a promising emerging therapy under the close supervision of our experienced team. All trial participants receive careful monitoring and comprehensive follow-up care to track outcomes and ensure safety throughout the process.
We recognize that every patient’s situation is unique. Our team will conduct a thorough evaluation — including imaging and clinical assessment — to determine whether GAE is appropriate for you. Patient selection criteria continue to be refined as research matures, and our goal is to match the right candidates with the procedure most likely to benefit them.
Looking Ahead
The future of GAE is bright. Advances in embolic materials, imaging technology, and molecular profiling are expected to further refine patient selection and broaden the procedure’s indications — potentially expanding its use to sports-related injuries and other musculoskeletal conditions beyond OA. With ongoing research and multidisciplinary collaboration, GAE has the potential to become a standard therapeutic option for a growing population of patients who need effective, lasting relief without surgery.
At Surgical Specialists of Ocala, we are committed to bringing innovative, evidence-based solutions to our patients. If you or a loved one is living with knee osteoarthritis and looking for options beyond traditional treatments, we encourage you to contact our office to learn more about the GAE clinical trial and whether you may be a candidate.
