Sports Medicine & Orthobiologics: Understanding Stem Cell Therapy and PRP

Sports medicine is a medical specialty focused on injuries and conditions that come from movement, training and overuse. Physician-led practices may include doctors trained in primary care sports medicine, orthopedics or physical medicine and rehabilitation, often working alongside physical therapists and athletic trainers.

Orthobiologics is a general term for substances taken from the body, or derived from biological sources, that are used in musculoskeletal care. Platelet-rich plasma (PRP) is one example: it is made from a person's own blood. Ultrasound-guided injections use live imaging to help a clinician place a needle in a chosen area, and rehabilitation uses guided exercise and activity changes.

It helps to be precise about regulation. 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, used in specialist transplant settings. Most clinic offerings described as stem cell therapy, including MSC, adipose or SVF, umbilical cord, Wharton's jelly, perinatal and exosome products, are not FDA-approved, and no exosome product is FDA-approved. The FDA has warned the public about unapproved stem cell and exosome products.

Tendon injuries, ligament sprains and conditions like tennis elbow have traditionally been approached with a mix of relative rest, activity modification, physical therapy and gradual strengthening. Bracing, supportive devices and medications chosen by a clinician have also been part of care.

When these steps are not enough, clinicians have sometimes discussed other options, such as image-guided injections or procedures, and in some situations surgery. Which options make sense depends on the person, the injury and an in-person evaluation, and a licensed clinician makes that decision.

Interest in PRP and other biologic injections has grown in sports medicine, but the evidence varies by condition and is often described as limited or still being investigated. Regulatory status can differ from product to product, so it is reasonable to treat any claim with healthy curiosity and ask for the details in writing.

The right physician-led practice may help you understand what is going on, what your options are and what is realistic. A first visit generally includes a conversation about your history and goals, a physical exam and sometimes imaging such as ultrasound. A good clinician explains the reasoning and does not promise an outcome.

Rehabilitation is often a central part of sports medicine, and a provider may coordinate with physical therapists or trainers around your sport or work. Some people find that having one team look at movement, training habits and the injury together helps them feel more informed and involved.

Helpful questions to ask: What is my diagnosis, and how was it reached? What are all my options, including not doing a procedure? Is this product or procedure FDA-approved, and if not, what is its status? Is any study registered on ClinicalTrials.gov with IRB oversight? Is your license verifiable with the state medical board? Can I have written informed consent covering risks and alternatives? Also check for red flags: cure-all or treats-everything claims, paying to join a clinical trial, testimonials offered in place of evidence, and pressure to travel abroad or across states. Calling a treatment holistic or alternative does not change its FDA status.
