Knee Pain Without Surgery: How Our Patients Are Finding Lasting Relief

If your knee pain has been building for months or years, and you have tried physiotherapy, injections, or rest without lasting results, there is a minimally invasive treatment that most Houston patients have never heard of. It does not involve surgery, hospital admission, or a long recovery. It is called Genicular Artery Embolization, and it is changing how knee arthritis is treated.

Living with Knee Pain

Knee pain has a way of quietly shrinking your world. It starts as a stiffness in the morning, a twinge on the stairs, a reason to park closer to the entrance. Before long, it is the reason you skipped the walk along Buffalo Bayou, turned down the weekend trip to Galveston, or stopped playing with your grandchildren the way you used to.

For the millions of Americans living with knee arthritis, this gradual narrowing of life feels inevitable. Doctors often frame the conversation as a choice between managing symptoms with medication and injections or eventually replacing the knee with surgery. Many patients spend years in that limbo, waiting for the pain to become bad enough to justify an operation they are not ready for.

What most patients in Houston, Katy, Cypress, and the surrounding areas have not been told is that there is a third option. One that does not require a hospital stay, general anaesthesia, or weeks of recovery. One that treats the source of the inflammation rather than masking it.

What Is Actually Causing Your Knee Pain

Most chronic knee pain related to arthritis is driven by inflammation. The joint lining becomes irritated, swells, and causes pain that is often worse in the morning, after sitting for a while, or when going up and down stairs.

What many patients and even many doctors do not fully appreciate is the role that blood supply plays in that inflammation. Abnormal blood vessel growth into the knee joint, a process called neovascularisation, feeds chronic inflammation. The more blood supply reaching the inflamed tissue, the more persistent and intense the pain becomes.

This is the insight that makes Genicular Artery Embolization possible. If you reduce blood flow to the inflamed tissue, you reduce the inflammation itself. And if you reduce the inflammation, you reduce the pain at its source.

What Is Genicular Artery Embolization

Genicular Artery Embolization, or GAE, is a minimally invasive procedure performed by an interventional radiologist. Dr. Bilal Anwer, who is Stanford Fellowship trained and CAQ Board Certified in Vascular and Interventional Radiology, performs GAE at Leg Pain and Vascular Institute’s Houston area clinics.

The procedure works by using image guidance, specifically X-ray fluoroscopy, to navigate a tiny catheter through a small nick in the skin, usually at the wrist or groin, to the genicular arteries surrounding the knee. Tiny microspheres are then delivered through the catheter to selectively reduce blood flow to the inflamed areas of the joint lining.

The entire procedure takes approximately 45 to 60 minutes. There are no large incisions, no stitches, and no general anaesthesia. Most patients go home the same day and return to light activity within 24 to 48 hours.

How GAE Is Different From Other Treatments

To understand why GAE matters, it helps to look at what most patients have already tried.

Physiotherapy and exercise can strengthen the muscles around the knee and reduce load on the joint. They are a valuable part of managing arthritis, but they do not address the underlying inflammation and often provide limited relief once arthritis has progressed.

Corticosteroid injections reduce inflammation effectively but temporarily. Most patients find that the benefit fades after a few weeks or months, and repeated injections over time can actually accelerate joint deterioration.

Hyaluronic acid injections aim to lubricate the joint but the evidence for their effectiveness in moderate to severe arthritis is mixed. Many patients find them helpful initially, only to see diminishing returns with each course.

Knee replacement surgery is a major operation that requires general anaesthesia, a hospital stay of one to several days, and a rehabilitation period of three to six months. It is highly effective for the right patient, but it is not something most people in their fifties or sixties are eager to pursue. And for patients who are not yet severe enough to qualify, surgery may be years away while the pain continues today.

GAE occupies a different category entirely. It is not a temporary mask and it is not a major operation. It targets the vascular component of knee inflammation at the source, producing results that develop gradually over four to eight weeks as the tissue responds to reduced blood supply.

Who Is a Good Candidate for GAE

GAE is not appropriate for every knee pain patient, but it is a strong option for a specific group that is currently underserved by the available treatments.

You may be a good candidate if you have knee pain caused by osteoarthritis that has been confirmed on imaging, you have tried conservative treatments including physiotherapy and injections without lasting relief, your pain is affecting your daily life, sleep, or mobility, and you are not ready for or do not qualify for knee replacement surgery.

Age is less of a limiting factor than many patients expect. Dr. Anwer has treated patients in their forties who were too young to be considered for surgery, as well as patients in their seventies and eighties for whom surgery carried too much risk. GAE is performed under local anaesthesia and light sedation, making it suitable for patients who could not safely undergo general anaesthesia.

Patients across the Greater Houston area, from The Woodlands to Pearland, from Sugar Land to Pasadena, come to Leg Pain and Vascular Institute specifically because GAE is not yet widely available and few centres in Texas offer it with the level of specialisation that Dr. Anwer brings.

What to Expect Before, During, and After GAE

Before the procedure, Dr. Anwer reviews your imaging, medical history, and symptoms at a consultation. He will confirm that your pain has a significant inflammatory component that is likely to respond to GAE and discuss whether it is the right approach for your specific presentation.

On the day of the procedure, you will arrive at the clinic and be prepared for the procedure with a local anaesthetic at the access site. Dr. Anwer uses real-time X-ray guidance throughout to navigate to the genicular arteries with precision. The procedure itself takes under an hour in most cases. You will rest briefly in recovery before going home the same day.

After the procedure, most patients experience some mild soreness at the access site for a day or two, which is normal. The knee itself may feel similar or slightly more tender for the first one to two weeks as the tissue begins to respond. Meaningful pain relief typically begins to develop between two and four weeks and continues to improve over the following months.

Follow-up imaging at four to eight weeks allows Dr. Anwer to confirm the outcome and assess the response to treatment.

What Patients Notice After GAE

The changes patients describe after GAE tend to be practical and specific. Getting out of bed without dreading the first few steps. Walking from the car park into the grocery store without stopping. Sitting through a full meal at a restaurant without shifting position every few minutes. Sleeping through the night.

These are not dramatic stories of miraculous recovery. GAE is not a cure for arthritis. It does not reverse cartilage loss or restore a joint to how it felt at thirty. What it does is meaningfully reduce the inflammatory pain that has been driving the limitation, often to a degree that makes daily life significantly more manageable.

For many patients, GAE buys years of better quality of life. For some, it delays or avoids surgery altogether. For others, it provides enough relief to re-engage with the physiotherapy and movement that further supports joint health.

Why GAE Is Not Yet Widely Known

GAE is supported by a growing body of clinical research and has been performed for knee arthritis since the early 2010s, with outcomes data now spanning more than a decade. Yet many patients and even many orthopaedic surgeons are not familiar with it.

The reason is largely structural. GAE is performed by interventional radiologists, not orthopaedic surgeons. Most patients with knee pain are referred within the orthopaedic pathway, where the conversation naturally focuses on surgical options. Interventional radiology is a speciality that operates largely outside that referral network.

Dr. Anwer trained specifically in vascular and interventional radiology at Stanford, one of the leading programmes in the country, and has built his practice around exactly these kinds of minimally invasive treatments that fall outside the traditional surgical pathway.

Taking the Next Step

If you have been living with knee pain in Houston, Katy, Cypress, Webster, or anywhere in the Greater Houston area, and you feel like you have exhausted your options, GAE may be the treatment you have not yet been offered.

No referral is required to book a consultation with Dr. Anwer. The first step is a conversation about your history, your imaging, and whether GAE is appropriate for your specific situation. There is no obligation and no pressure.

Leg Pain and Vascular Institute has clinics in Houston on FM 1960 and in Webster on Gulf Freeway, with appointments available to suit most schedules. Most major insurance plans are accepted, including Medicare.

Knee pain may have been slowing you down for years. It does not have to continue to.
