What it is
Orthopedics and sports medicine focus on bones, joints, muscles, tendons, and ligaments. A visit usually begins with an evaluation of the problem, which may include a physical exam, a review of your history, and sometimes imaging. Only a licensed clinician can decide what is appropriate for you after an evaluation.
Some practices also offer injections marketed as stem cell treatments. These may include bone marrow aspirate concentrate (BMAC), adipose-derived (fat) products, umbilical cord or Wharton's jelly products, and exosome products. They are often promoted for joints, tendons, and sports injuries.
Here is the plain regulatory picture. Blood-forming stem cell transplants from bone marrow or cord blood, used for certain cancers and blood disorders, are the clearly FDA-approved use. Stem cell, MSC, bone marrow aspirate, adipose-derived, umbilical cord, and exosome products marketed for joint pain, osteoarthritis, or sports injuries are generally not FDA-approved for those uses, and the FDA has publicly warned about unapproved stem cell clinics and products.
How it’s traditionally been approached
Orthopedic care has traditionally begun with the least invasive options. Depending on the situation, a clinician may discuss rest, activity changes, physical therapy, bracing, or medications. Which of these fit you is a decision for you and your provider.
For some conditions, clinicians have also discussed injections or surgical options, with the choice depending on the diagnosis and the individual. Sports medicine often looks at movement, training habits, and recovery along with the injury itself.
Biologic injections, including those marketed as stem cell treatments, are a newer and more debated part of the field. Some clinicians offer them, some caution against them, and the regulatory status of many products remains unapproved for these uses. Reasonable professionals can hold different views, and a good provider will explain theirs openly.
How the right provider may help
The right orthopedic or sports medicine provider may help you understand what is going on in your joint or tendon, what the options are, and what the evidence does and does not show. A visit generally includes questions about your pain, activity, and goals, a physical exam, and possibly imaging. A thoughtful provider may also talk through alternatives, including doing nothing for now.
If a stem cell or biologic injection is mentioned, you can ask: What exactly is the product, and where does it come from? What is its FDA status for this use? What are the specific risks? What is the realistic chance of benefit? What are the alternatives? What is the total cost, disclosed up front? A trustworthy provider should answer plainly and welcome a second opinion.
Reported risk categories for unapproved products include infection, immune reaction, and tumor formation at the injection site. Permanent injury has been reported when unapproved products were injected into the eye or spine. You may also ask whether a registered clinical trial, searchable on ClinicalTrials.gov, could be a legitimate route to experimental care. Treatment abroad carries materially higher risk because safety, sourcing, and regulatory standards differ and complications are harder to address from a distance, so a vetted domestic provider is a safer first step.
The whole-person view
Chronic pain and injury affect more than the joint. Worry, poor sleep, and stress can change how pain is felt, and pain can in turn limit movement, mood, and confidence. Looking at the whole person, including body, mind, and stress, is often part of good care.
Some people explore body-based support such as Somatic Experiences alongside medical care to build awareness of tension and stress in the body. Others find talk therapy through Therapists.plus helpful for coping with pain, frustration, or the pressure of a sports setback. These are possibilities, not promises, and they do not replace medical evaluation.

Keep in mind
- Stem cell injections for joints and tendons are generally not FDA-approved; always ask what exact product is used and its FDA status before agreeing to anything.
- Red flags: guarantees of results, words like "cure" or "regrow," refusal to name the product or its FDA status, pressure to decide quickly, and discouraging a second opinion.
- Informed consent should cover the exact product and FDA status, specific risks, realistic chance of benefit, alternatives including doing nothing, total cost disclosure, and your right to walk away. This page is not a consent form.
- To report a suspected problem, you can use the FDA's MedWatch safety reporting program and your state medical board. Serious conditions should be guided by licensed professionals; for emergencies call 911, and in a crisis call or text 988.

Frequently asked questions
Is stem cell therapy safety a concern for knee pain and osteoarthritis?
Yes, it is an important concern. Stem cell and similar products marketed for knee pain and osteoarthritis are generally not FDA-approved for those uses, and the FDA has warned the public about unapproved clinics. Reported risk categories include infection, immune reaction, and tumor formation at the injection site, so ask a licensed clinician about the specific product.
Are stem cell injections FDA-approved for joints and tendons?
Generally no. The clearly FDA-approved use of stem cells is blood-forming transplants from bone marrow or cord blood for certain cancers and blood disorders. Products marketed for joints, tendons, and sports injuries are generally not approved for those uses.
What is bone marrow aspirate concentrate (BMAC)?
BMAC is a preparation made from a person's own bone marrow that is concentrated and then sometimes injected into a joint or injured area. It is often marketed as a stem cell treatment for orthopedic problems, but it is generally not FDA-approved for those uses. Ask a provider about its regulatory status, risks, and realistic chance of benefit.
What are red flags at a stem cell clinic?
Warning signs include guarantees of results, language like "cure" or "regrow," refusing to name the product or its FDA status, pressure to decide quickly, and discouraging a second opinion. Any one of these is a reason to pause and seek another opinion.
Is it safe to get stem cell treatment abroad?
Treatment abroad is materially higher risk. Safety, sourcing, and regulatory standards differ, and it is harder to address a complication from a distance. A vetted domestic provider is a safer first step.
How can I access experimental stem cell care legitimately?
A registered clinical trial is one legitimate route. You can search ClinicalTrials.gov for studies and discuss eligibility with your clinician. If you have a problem after any treatment, you can report it through the FDA's MedWatch program and your state medical board.
