Knee arthritis, chronic back pain, and stiff, aching joints can make everyday life harder, and it is natural to look for an option that promises healing without surgery. Stem cell therapy is widely marketed for exactly that. Patients in Beverly Hills and Los Angeles deserve a clear view of what the research shows for knees, backs, and arthritis today, how these products are regulated, and which treatments have the strongest evidence for relieving pain and protecting mobility.
Joint pain has many causes, and telling them apart is where Dr. David Nazarian’s training matters most. His internal medicine residency at Huntington Memorial Hospital, a USC teaching affiliate, included a rheumatology rotation at Los Angeles County+USC Medical Center, preparing him to distinguish osteoarthritis from inflammatory conditions such as rheumatoid arthritis, gout, and psoriatic arthritis, which require very different care. He is a diplomate of the American Board of Internal Medicine and a member of the American College of Physicians.
“Joint pain has many causes, and they are not treated the same way. Rheumatoid arthritis, gout, and osteoarthritis can look alike at first, and getting that distinction right protects the joint.” — Dr. Nazarian
I have been seeing Dr. Nazarian for more than 5 years now and I am grateful for all the care he has given me. He is one of the most caring and professional doctors I have ever seen and he genuinely cares about all his patients. I will continue to entrust him with my health care for many years to come. Thanks Dr. Nazarian – Andrew
What the Research Shows for Knee, Back, and Arthritis Pain
Cell-based joint treatments typically use bone marrow concentrate, fat-derived preparations, or donor birth tissue products, injected into or around a joint. The evidence differs by condition:
- Knee Osteoarthritis: A large randomized trial published in 2023 found that bone marrow, fat-derived, and umbilical cord-derived cell injections were not superior to a corticosteroid injection for knee pain at one year, and regrowth of cartilage has not been demonstrated in people.
- Low Back and Disc Pain: Injecting cells into spinal discs remains investigational, with limited human data and procedure-related risks.
- Rheumatoid and Inflammatory Arthritis: Stem cell injections are not a treatment for these autoimmune conditions, which are managed with proven disease-modifying medications that help prevent joint damage.
- Tendon and Soft Tissue Injuries: Research on cell-based injections is early, and outcomes vary widely across studies.
The FDA has stated that regenerative medicine products have not been approved to treat any orthopedic condition, including osteoarthritis, disc disease, and back, knee, or hip pain. Its consumer information on regenerative medicine explains that unapproved products generally require FDA oversight in a clinical trial. More detail on product types is available on our stem cell injections page.
Common Joint Concerns and Proven Treatment Options
For knee and hip osteoarthritis, clinical guidelines consistently support a core set of treatments, and many patients improve substantially with them:
- Structured exercise and physical therapy to strengthen the muscles around the joint
- Weight management, which reduces load on weight-bearing joints
- Topical and oral anti-inflammatory medications when appropriate
- Corticosteroid injections for flares, and bracing or walking aids when helpful
- Joint replacement surgery for advanced arthritis that limits daily life
Platelet-rich plasma (PRP) is one biologic option with more supporting research for knee osteoarthritis than cell-based injections, and orthopedic guidelines describe it as a possible option for pain with limited-strength evidence. Learn more on our growth factor injections page.
Some joint and back symptoms need urgent attention. Go to the emergency room or call 911 for a hot, swollen joint with fever, back pain with new leg weakness, numbness in the groin or inner thighs, or loss of bladder or bowel control.
What to Expect During Your Joint Pain Evaluation
Your visit in Beverly Hills begins with a detailed history and examination of the affected joint or spine. Dr. Nazarian reviews prior X-rays or MRIs and may order blood tests to check for inflammatory arthritis, gout, or other conditions. From there, he outlines a plan that may include physical therapy, medications, injections, or referral to an orthopedic surgeon or rheumatologist through our primary care and internal medicine services. If you are interested in cell-based therapy, he will review the evidence and regulatory status honestly and help you evaluate legitimate clinical trials.
Frequently Asked Questions About Stem Cell Therapy for Joint Pain
-
Cartilage regrowth has not been demonstrated in people. A large 2023 randomized trial found cell-based knee injections were not superior to a corticosteroid injection for pain at one year.
-
No. The FDA has stated that regenerative medicine products are not approved for any orthopedic condition, including osteoarthritis and back pain. Unapproved products generally require FDA oversight in a clinical trial.
-
Corticosteroid injections are a standard option for arthritis flares, and PRP has more research than cell-based injections for knee osteoarthritis. See our growth factor injections page for details.
-
Cell injections for back and disc pain are investigational. Many back pain episodes improve with physical therapy and time, and persistent pain deserves a careful diagnosis.
-
No. Rheumatoid arthritis is an autoimmune disease treated with proven medications that reduce inflammation and help prevent joint damage, usually in partnership with a rheumatologist.
-
Persistent pain that limits daily activities, joint instability, or advanced changes on imaging may warrant an orthopedic evaluation. Dr. Nazarian coordinates these referrals directly. Learn more about product types on our stem cell injections page.
