Dr. Ilana Etelzon treats knee, shoulder, and back pain across South Brooklyn with regenerative medicine that repairs the problem at the source. She specializes in helping active women in their 40s, 50s, and 60s get back to the activities they love, and treats patients of every age and activity level the same way. PRP, bone marrow concentrate, MLS laser therapy, and shockwave are used together to target what is driving your pain.
Most people who come to our Brooklyn office want the same thing: to move without bracing, sleep without aching, and get back to what they have been putting off. Regenerative medicine makes that realistic by repairing the tissue behind the pain instead of masking it. Dr. Etelzon's first job is finding what is actually driving your knee, shoulder, or back pain, using fluoroscopic and ultrasound imaging rather than guessing at it.
She is known for helping active women in their 40s, 50s, and 60s who were told their pain was just age, and she treats patients of every age and activity level the same way. Once she knows what is driving the pain, she often pairs treatments from the first visit so one area can be calmed and rebuilt at once. PRP and bone marrow concentrate work on the underlying tissue, while MLS laser therapy and shockwave reduce inflammation and improve blood flow around the joint. These are regenerative treatments patients invest in directly, chosen because they repair the problem instead of covering it, so progress holds instead of fading in a few weeks.

Each option can stand on its own or be combined into one plan based on what your joint or spine actually needs.

Learn about stem cell injections ›A focused light therapy that calms inflammation and eases pain, often used alongside an injection plan.
Learn about MLS laser ›Targeted acoustic waves that stimulate circulation and healing in stubborn soft-tissue and tendon pain.

Regenexx is a national network of physicians who follow specific protocols for how cells are collected, concentrated, and placed. Becoming a certified provider takes training and ongoing review, and only a small number of doctors in the New York area hold the credential. Dr. Etelzon is one of them.
For you, that means your treatment follows a tested, standardized method rather than a one-off approach, and that the lab work behind your injection is held to the same standard used across the Regenexx network.
Care and consultations are available in English, and the Brooklyn team also speaks Russian and Ukrainian.

Clinical OversightTwo patients with knee pain rarely need the same thing. Dr. Etelzon uses fluoroscopy and ultrasound to see exactly where the problem sits before anything is placed, then decides whether one treatment or a combination will get you back to your activities fastest. The imaging is part of why placement is precise and why so many patients avoid a more invasive route.
"I want patients to leave with a plan that fits their body and their life, not a generic protocol. When I can see the joint clearly and pair the right treatments, people get back to the things they love much sooner than they expected."
