GAE vs. Knee Replacement: Which Is Right for You?

When knee pain starts to limit your daily activities, choosing the right treatment can feel overwhelming. At United Knee & Vascular Centers, we specialize in helping patients understand all their options so you can move forward with confidence.

Genicular Artery Embolization and total knee replacement surgery are two proven, but distinctly different, options for treating chronic knee pain due to osteoarthritis. While both can offer long-term relief, they differ in how they work, how invasive they are, and what recovery looks like.

Let’s compare the two to help you make an informed decision.

What Is Genicular Artery Embolization (GAE)?

GAE is a minimally invasive vascular, outpatient procedure that reduces osteoarthritis-associated knee pain by blocking abnormal blood flow to the inflamed areas of the joint. It is typically performed by an interventional radiologist using advanced imaging and does not involve any surgical incisions into the joint itself.

Benefits of GAE

• No general anesthesia or hospital stay, only local anesthesia required 
• Short recovery time (most return to activities within 24–48 hours)
• Preserves your natural joint
• Effective for patients with mild to moderate osteoarthritis 

What Is Knee Replacement Surgery?

Knee replacement, or total knee arthroplasty, is a major orthopedic surgery that involves removing damaged cartilage and bone from the joint and replacing it with a prosthetic implant. It’s often recommended for patients with severe joint degeneration.

Considerations for Knee Replacement

• Requires general or spinal anesthesia
• Involves a hospital stay and physical therapy
• Recovery may take several months 
• Suitable for advanced or bone-on-bone arthritis

Which Option Is Right for You?

The best treatment depends on the severity of your arthritis, your overall health, and your lifestyle goals. Many patients who aren’t ready to undergo or who are not ideal candidates for traditional surgery find GAE to be an effective alternative that offers real pain relief and improved mobility.
