Best Stem Cell Therapy in Newport Beach: Top 5 Physician-Led Clinics for 2026

Stem cell injections for knee, hip, shoulder and back pain are widely advertised in Orange County, and clinics vary. Some are led by physicians who use the patient's own bone marrow or fat and guide each injection with imaging; others are run by non-physicians or use donor products whose contents are hard to verify.

Two facts help sort them. First, the U.S. Food and Drug Administration has not approved any stem cell product for joint, tendon or spine conditions; the stem cell products it has approved are blood-forming cells from umbilical cord blood, used for certain blood disorders. Second, California law requires practitioners who offer stem cell therapies that are not FDA approved to post a notice saying so and to give it to patients in writing before treatment. This guide compares five physician-led Newport Beach clinics. Regenerative Institute of Newport Beach ranks first for patients who want a board-certified physical medicine and rehabilitation physician to weigh stem cell therapy against every other option, from PRP to spine procedures, in one office.

Quick Comparison Table: Newport Beach Stem Cell Clinics

1. Regenerative Institute of Newport Beach

Why they lead the list: Stem cell therapy is one option at Regenerative Institute of Newport Beach, not the only one. Dr. Khyber Zaffarkhan is board certified by the American Board of Physical Medicine and Rehabilitation and completed residency at Tufts Medical Center and UCLA with the VA Greater Los Angeles. In the same practice he offers PRP, alpha-2-macroglobulin (A2M) and hyaluronic acid injections for joints, plus epidural injections, nerve blocks, radiofrequency ablation and spinal cord stimulation for spine pain, with procedures performed in an on-site surgery center. That range lets a patient hear whether stem cells, a simpler injection or a spine procedure is the better fit for their problem.

What They Do Well

• Image guidance: Injections guided by ultrasound or fluoroscopy, as the practice describes them.
• Video consultations: Patients outside Orange County can start with a video visit before traveling.
• Spanish-speaking staff: A nurse practitioner and a physician assistant support Dr. Zaffarkhan, and the front office can help patients in Spanish.

Ideal Customers: Adults with knee, hip, shoulder, back or neck pain who want to explore options before joint replacement or spine surgery.

Standout Features

• Wide treatment menu: Osteopathic manipulation, Botox for migraine and SoftWave therapy are offered alongside injections.
• On-site surgery center: Procedures performed at the Newport Beach office.
• Medical-legal work: Independent medical exams and life care planning for injured patients and attorneys.

Bottom line: The pick for patients who want one physician to weigh stem cell therapy side by side with every other option before choosing.

What Patients Say: Reviewers on WebMD and other platforms most often describe a doctor who listens, explains the condition and procedure clearly, and works to find the source of their pain, along with friendly, helpful staff. 

Good fit for: Comparing all options.

2. Patel Center for Functional Regeneration

What They Do Well

• Patient's own cells: Orthobiologic injections using the patient's own platelets, bone marrow cells and fat graft.
• Orthobiologics teaching: Dr. Patel is a Master Instructor with the Interventional Orthobiologics Foundation and co-authored the American Academy of Physical Medicine and Rehabilitation's guidance on PRP for knee osteoarthritis, per his site.
• Ultrasound training: Co-author of a musculoskeletal ultrasound atlas that won a 2019 PROSE Award from the Association of American Publishers, per his site.

Ideal Customers: Patients with knee, hip, shoulder, spine or tendon problems who want an orthobiologics-focused physician. Dr. Patel completed residency at the Kessler Institute for Rehabilitation and a fellowship at OSS Health, and opened the Newport Beach office in 2022.

Bottom line: A strong choice for patients who want a physician whose practice centers on orthobiologic injections.

What Patients Say: Google reviewers most often describe a doctor who takes unhurried time on the first visit, explains everything clearly, looks for non-surgical answers first and has kind, friendly staff. 

Good fit for: Orthobiologic focus.

3. Orange County Spine and Sports Physicians

What They Do Well

• Ultrasound guidance: PRP and stem cell injections delivered under ultrasound as same-day outpatient procedures.
• Range of sources: Its regenerative page lists the patient's own fat or bone marrow as well as placental and umbilical cord tissue, so patients should ask which source a plan uses.
• Soft-tissue focus: Tendon tears, ligament injuries, rotator cuff injuries and tendinitis, along with knee, back and neck pain.

Ideal Customers: Weekend athletes and other active patients who would like a spine and sports physician to place regenerative injections, with insurance questions sorted out before the visit. Dr. Babaria holds the RMSK credential in musculoskeletal ultrasound.

Bottom line: The largest review base on this list, for active patients weighing regenerative and conventional spine care.

What Patients Say: Google reviewers most often describe a physician who listens and explains complex findings simply, fast scheduling, and kind, efficient staff. 

Good fit for: Active adults who want insurance help.

4. The Goswami Clinic

What They Do Well

• State notice online: The California notice that the clinic performs stem cell therapies not approved by the FDA appears on its stem cell page.
• Plain disclaimer: Its site says results are not assured and that treatment may help symptoms in properly selected patients.
• Ask about source: The stem cell page does not say whether cells come from the patient or a donor, so patients should ask.

Ideal Customers: Patients with degenerative disc disease, herniated discs, joint or tendon injuries who want an interventional radiologist to place the injection. Dr. Goswami's Medical Board of California record lists American Board of Radiology certification and no public disciplinary actions, and the clinic dates to 2009.

Bottom line: A practical option for spine and disc patients who value an imaging specialist at the needle.

What Patients Say: Google reviewers most often describe a compassionate, caring physician who spends time with patients and name staff members Ruby and Sandra for their support through consultation and procedure day. 

Good fit for: Spine and disc injections.

5. OC Regenerative and Pain Center

What They Do Well

• Own cells only: Bone marrow aspirate concentrate (BMAC) or microfragmented adipose tissue (MFAT), both from the patient.
• Plain risk language: Its site states that PRP and cellular therapies are investigational for many orthopedic uses and that results vary.
• Pain procedures: Image-guided joint and spine injections alongside regenerative care.

Ideal Customers: Patients with neck, back or joint pain who want a pain medicine physician and clear language about what is still unproven. Dr. Shahbazian completed anesthesiology residency and a pain medicine fellowship at USC and opened this Newport Beach practice in 2025.

Bottom line: A newer practice with an established physician and unusually candid wording about investigational treatment.

What Patients Say: Google reviewers most often describe "Dr. Mike" taking time to listen and explain treatment options, kind and professional staff, and a clean, well-run office. 

Good fit for: Patients who want plain risk language.

How These Clinics Were Ranked

Primary factors

• Physician-led: Care led by a licensed MD or DO, with license status checked where the state record was available. Clinics run by chiropractors or med spas were excluded.
• Cell source and guidance: Whether the clinic says where its cells come from and how injections are guided.
• Local office and record: A medical office in Newport Beach, no disciplinary actions or FDA warning letters found, and positive ratings and reviews. 

Secondary factors

• Honest limits: Clear statements that treatment is not FDA approved for these uses and that results vary.
• Training: Residency, fellowship and board certification in a musculoskeletal or interventional specialty.
• Range of care: Other options offered when stem cells are not the right fit.

Final Word

Stem cell therapy for joint and spine pain is still investigational, so the clinic and physician matter as much as the treatment. Regenerative Institute of Newport Beach ranks first because a board-certified physical medicine and rehabilitation physician can compare stem cell therapy with PRP, other injections and spine procedures in one office.

Before booking, ask any clinic where its cells come from, whether the injection will be guided by ultrasound or fluoroscopy, what the total price includes, and to see the California stem cell notice.
