What it is
Stem cell therapy is a broad phrase. It is often used for clinic-based injections made from bone marrow, fat tissue (adipose or SVF), umbilical cord, Wharton's jelly, or other perinatal sources. Related terms include orthobiologics, such as platelet-rich plasma (PRP), and exosome products. These are very different things, and the label alone does not tell you what is actually in a product.
Regulatory status matters. In the U.S., the only FDA-approved stem-cell products are cord-blood-derived hematopoietic progenitor cell (HPC) products, used in specialist transplant settings for certain blood and immune disorders. Most clinic stem-cell, MSC, adipose/SVF, umbilical cord, Wharton's jelly, and perinatal treatments are not FDA-approved. No exosome product is FDA-approved, and the FDA has warned the public about unapproved stem cell and exosome products.
For joints, spine, sports injuries, skin, and hair, research is ongoing and the evidence is limited or investigational. Phrases like regenerative medicine for knee pain, stem cells for rotator cuff, regenerative injection for back pain, and stem cell skin rejuvenation describe what people search for, not proven results. 'Holistic' or 'alternative medicine' framing does not change a product's FDA status.
How it’s traditionally been approached
Joint pain, including the knee and shoulder, has traditionally been approached with a licensed clinician's evaluation, activity changes, physical therapy, and a range of medications or injections. In some cases, surgery is discussed. Which of these fits depends on the person and the diagnosis.
Back and spine concerns have likewise been addressed through conservative care, movement-based rehabilitation, pain management approaches, and sometimes procedures. Sports injuries often involve rest, rehabilitation, gradual return to activity, and guidance from sports medicine professionals.
Skin and hair concerns have traditionally been brought to dermatology and aesthetic professionals, who may discuss topical products, in-office procedures, and other established options. Newer regenerative offerings are often marketed alongside these, so it helps to ask what is established and what is still being studied.
How the right provider may help
The right provider, such as a licensed physician in orthopedics, sports medicine, physiatry, pain medicine, or dermatology, may help you understand your diagnosis and the full range of options. A visit generally includes a history, a physical exam, possibly imaging, and a conversation about your goals. Only a licensed clinician can decide what is appropriate for you after an evaluation.
If a regenerative option comes up, good questions include: Is this product FDA-approved for this use? Is it part of a study registered on ClinicalTrials.gov with IRB oversight? What are the risks, the alternatives, and the limits of the evidence? Ask for written informed consent that covers risks and alternatives.
Before committing, confirm the clinician's license with your state medical board. Be cautious of red flags: cure-all or 'treats everything' claims, being asked to pay to join a 'clinical trial', testimonials offered in place of evidence, and pressure to travel abroad or across states for treatment. A trustworthy provider should welcome your questions and a second opinion.
The whole-person view
Body, mind, and stress affect each other. Ongoing pain can raise tension, disturb sleep, and shape mood, while stress can make pain feel more intense. Looking at the whole person, including movement, rest, and emotional well-being, can be a helpful complement to any medical evaluation.
Some people explore body-based support such as Somatic Experiences to build awareness of tension and stress held in the body. Others find talk therapy through Therapists.plus useful for coping with the worry and frustration that can come with persistent pain or injury. Neither replaces a licensed clinician's care, and both are simply options to consider.

Frequently asked questions
Is stem cell therapy FDA-approved for knee pain?
No. In the U.S., the only FDA-approved stem-cell products are cord-blood-derived hematopoietic progenitor cell (HPC) products for certain blood and immune disorders. Stem cell therapy marketed for knee pain is generally not FDA-approved. Ask a licensed clinician about the regulatory status of any product.
Does regenerative medicine for knee pain really work?
The evidence is limited or investigational, and no outcome can be promised. Research is ongoing, and results vary by person, product, and condition. A licensed clinician can explain established options alongside any regenerative ones.
Are stem cells used for rotator cuff injuries?
Some clinics offer stem cells for rotator cuff problems, but these offerings are mostly not FDA-approved and the evidence is limited. Traditional care often begins with an evaluation and rehabilitation. Ask a provider about options, risks, and alternatives.
What are orthobiologics for sports injuries?
Orthobiologics are substances derived from the body's own biology, such as PRP or cell-based preparations, that some clinicians use for musculoskeletal problems. Their regulatory status and evidence vary, and many cell-based products are not FDA-approved. A sports medicine clinician can explain what applies to your situation.
Is stem cell therapy for hair restoration or skin rejuvenation proven?
No, these uses are not proven and are not FDA-approved. Evidence is limited or investigational, and the FDA has warned about unapproved stem cell and exosome products. A board-certified dermatologist can discuss established options and how to evaluate newer claims.
How do I find a trustworthy provider for stem cell therapy?
Start by confirming the clinician's license with your state medical board. Ask whether the product is FDA-approved, whether any study is registered on ClinicalTrials.gov with IRB oversight, and request written informed consent covering risks and alternatives. Be wary of cure-all claims, paying to join a 'trial', testimonials instead of evidence, and pressure to travel.
