Regenerative medicine is reshaping how physicians and patients think about healing. Rather than managing pain from the outside in, it works from the inside out, using the body’s own biology to repair damaged tissue, restore function, and help people get back to the activities that make life worth living.
For patients who have spent years cycling through treatments that offer temporary relief but never quite solve the problem, regenerative medicine offers something different: a path toward actual healing.
Dr. Ilana Etelzon, MD, a double board-certified interventional pain specialist and Regenexx Core Provider at Pain Doctors Medical, has built her practice around this approach. Here, she explains what regenerative medicine actually does, how it works, and why the outcomes consistently go beyond what patients expect.
It Aims to Heal the Tissue, Not Just Quiet the Pain
Most patients arrive at Pain Doctors Medical having tried treatments that focused on managing their symptoms. That approach can be valuable. But it does not address what is actually wrong.
“Most treatments focus on managing symptoms,” Dr. Etelzon says. “Regenerative medicine focuses on helping your body heal the underlying injury.”
In practice, that means using the body’s own healing cells and growth factors to support tissue repair, improve function, and potentially help patients avoid more invasive interventions. The goal is not temporary relief. It is helping the damaged area function better over the long term.
That distinction matters more than it might seem. Chronic pain is often a symptom of tissue dysfunction, not just a signal to be turned down. When the tissue itself heals, patients tend to experience more durable improvements, not just in pain levels but in what they can actually do.
What Is Actually Happening at the Tissue Level
One of the most common questions Dr. Etelzon gets is how regenerative treatments are different from a cortisone injection. The short answer: cortisone reduces inflammation and can provide meaningful relief, but it does not repair anything. Used repeatedly, it may actually have negative effects on tissue health over time.
Regenerative treatments work differently. They deliver concentrated growth factors and healing signals that help the body recruit repair cells, improve blood flow, and support the healing response within injured tissues. Tendons, ligaments, joints, and cartilage are given a biological environment in which they can recover.
“What many patients don’t realize is that pain is often a symptom of tissue dysfunction,” Dr. Etelzon explains. “While cortisone can quiet the pain signal, regenerative medicine aims to improve the health of the tissue itself, which may lead to more durable improvements in pain and function.”
The Four Treatments at Pain Doctors Medical
At Pain Doctors Medical, Dr. Etelzon uses four core regenerative and supportive modalities: platelet-rich plasma (PRP) injections, bone marrow concentrate (often referred to as stem cell therapy), MLS laser therapy, and shockwave therapy. What sets her approach apart is that she rarely uses just one.
“In many cases, the best results come from combining treatments because healing is multifaceted,” she says. “Just as you wouldn’t build a house with only one tool, we often use a strategic combination of regenerative procedures and supportive therapies to create the best environment for healing.”
Here is how each one works:
PRP injections use a concentrated preparation of the patient’s own platelets, rich in growth factors. PRP is often well-suited for mild to moderate injuries and inflammation in tendons, joints, and soft tissue.
Bone marrow concentrate draws on the regenerative cells found in the patient’s own bone marrow. It is typically reserved for more advanced degeneration or complex cases where a more potent biological signal is needed.
Shockwave therapy delivers acoustic energy to stimulate healing and improve blood flow, making it particularly useful in chronic tendon injuries that have been resistant to other treatments.
MLS laser therapy uses synchronized wavelengths of light to reduce pain and inflammation and support the recovery process, often used alongside other regenerative procedures.
The treatment plan for each patient starts from scratch. Dr. Etelzon considers the diagnosis, the severity of tissue damage, the patient’s goals, and what they have already tried. No two plans look exactly the same.
Why the Regenexx Credential Matters
Regenerative medicine is a field where technique matters enormously. The quality of the biologic product, how it is processed, and the precision of where it is placed can all affect outcomes significantly.
Dr. Etelzon is a Regenexx Core Provider, which means she has completed advanced training in image-guided regenerative orthopedic procedures and follows strict clinical protocols. Regenexx procedures are performed using imaging guidance to accurately target the specific structures involved, rather than injecting a general area.
“It’s not just about what is injected,” Dr. Etelzon says. “It’s about how, where, and why it’s done. Those details can make a meaningful difference in the care patients receive.”
Patients also benefit from protocols refined over many years and access to one of the largest regenerative medicine outcome databases in existence. That level of rigor is not universal in this space, and it is one reason patients travel to Pain Doctors Medical from across New Jersey and New York.
The Result That Surprises Patients Most
When patients come in, they are hoping their pain will improve. That is usually not the thing that surprises them.
“The biggest surprise is usually not the pain relief. It’s getting their life back,” Dr. Etelzon says. “I’ve had patients get back to golfing, hiking, playing tennis, traveling comfortably, exercising, getting down on the floor with their grandchildren, or simply walking without constantly thinking about their pain.”
The activities patients describe are rarely extreme. They are things most people take for granted until they cannot do them anymore. A long walk. A flight without dread. A round of golf with friends. Weekend hikes. Time with grandchildren that does not end in pain.
The moment Dr. Etelzon finds most rewarding is when a patient says: “I stopped doing that years ago because I thought I’d never be able to again.”
That is the metric regenerative medicine is measured by at Pain Doctors Medical. Not just pain scores. Restored function, restored confidence, and a return to the life the patient had before things started breaking down.
Is Regenerative Medicine the Right Next Step for You?
Regenerative medicine is not a fit for everyone, and Dr. Etelzon will tell you that directly. But for patients who have not found lasting relief through conventional treatments and are looking for an alternative to surgery or long-term medication, it is worth a real conversation.
Pain Doctors Medical sees patients at four locations: Clifton NJ, Newark NJ, Perth Amboy NJ, and Brooklyn NY. Consultations with Dr. Etelzon begin with a thorough evaluation of your history, imaging, and goals before any treatment is recommended.
If you have been quietly adjusting your life around pain for years, it may be time to find out whether there is another option.
