Genicular Artery Embolization vs. Total Knee Replacement
There is now a less costly and safer alternative to total knee replacement for those suffering from chronic knee pain.
Among all adults, knee pain is considered one of the most prevalent issues, especially for people above the age of 50. For a large portion of these individuals, knee osteoarthritis seems to be the culprit, also known as ‘degenerative joint disease.’ It is defined as a condition that causes the affected joint to undergo wear and tear, leading to decreased mobility and reduced quality of life. It was previously believed that a total knee replacement (TKR) is an absolute necessity for the more severe cases, but it is not the only approach.
A considerable percentage of patients these days are turning towards Genicular Artery Embolization (GAE), a minimally invasive approach that provides major pain relief without a lengthy recovery time or the high costs incurred from surgeries.
Defining Genicular Artery Embolization
GAE is a relatively new term for a process done by an interventional radiologist and does not involve surgery. It aims to lower the amount of blood supply to the inflamed portions around the knee joint, which helps relieve pain and inflammation. The procedure can be performed outside of a hospital setting and does not last more than two hours. In addition, patients do not have to spend the night in the hospital.
GAE vs Total Knee Replacement Recovery
The difference in the recovery period is one of the most critical motivators for patients choosing GAE over TKR. After total knee replacement, a patient’s recovery period includes 6 to 12 months of multifaceted physical rehabilitation. By contrast, most GAE patients report the ability to perform normal activities within a week or two, and many start experiencing pain relief within a month.
According to a clinical study published by the Society of Interventional Radiology, average pain scores decreased from 8 out of 10 to 3 out of 10 within the first week of the procedure.
Risk & Cost Comparison
Total knee replacement entails risks like any other surgical operation—an infection, clot formation within the blood vessels, and anesthesia complications. As noted by the American Academy of Orthopaedic Surgeons, TKR patients’ postoperative pain can persist in up to 20% of cases, regardless of intervention. In some instances, due to the nature of the problem, revision surgery becomes necessary, more commonly in younger or active patients.
In contrast, GAE carries a significantly lower risk profile. Difficulties are infrequent because it does not involve cutting the joint or excising any tissue. Most complications are minor, like temporary bruising or soreness around the catheter placement site and possible skin irritation over the knee. Unlike knee replacement, GAE can be repeated and is reversible.
Total knee replacement can be a financial burden. In the U.S., the average cost ranges from $30,000 to $50,000, depending on the hospital and insurance coverage. GAE is generally much more affordable, averaging between $6,000 and $12,000, and may be partially covered by insurance.
Is GAE Right for You?
While GAE isn’t suitable for everyone—especially those with advanced joint degeneration or structural deformities—it can be a game-changer for patients with moderate to severe osteoarthritis who want to avoid surgery.
If you’ve been told that knee replacement is your only option, it’s worth getting a second opinion. GAE could offer the relief you’re looking for—without the months of recovery, surgical risks, or high price tag.
