PRP therapy vs stem cell therapy
PRP concentrates the growth factors already in your blood; stem cell therapy introduces cells harvested from fat, bone marrow, or donor tissue. PRP costs less and is more widely available, stem cell therapy is typically used for more advanced degeneration, and evidence quality varies for both.
How each one works
Platelet-rich plasma (PRP) starts with your own blood. A sample is spun in a centrifuge to separate out a platelet-dense fraction, which is then injected into the treatment site. The intent is to concentrate the growth factors platelets already carry.
Stem cell therapy uses cells rather than plasma. Depending on the protocol, those cells come from your own adipose tissue or bone marrow (autologous), or from donated umbilical-cord or placental tissue (allogeneic). Some clinics also offer exosomes, which are cell-derived signalling vesicles rather than cells.
Both are usually delivered as an outpatient injection, often under ultrasound or fluoroscopic guidance so the material reaches the intended structure.
PRP vs stem cell therapy at a glance
| PRP | Stem cell therapy | |
|---|---|---|
| What is injected | Concentrated platelets from your own blood | Cells from your fat or bone marrow, or from donor tissue |
| Typical US cost per session | $500–$2,000 | $4,000–$12,000+ |
| Collection procedure | Blood draw, same visit | Liposuction or bone-marrow aspiration (autologous), or none (donor tissue) |
| Chair time | Under an hour | Half a day for autologous harvesting |
| Downtime | Usually days; soreness at the site is common | Days to weeks, mostly from the harvest site |
| Commonly offered for | Tendinopathy, mild-to-moderate osteoarthritis, sports injuries | More advanced joint degeneration, and systemic protocols |
| Regulatory position (US) | Minimally manipulated autologous blood product | Varies by cell source and processing; many protocols are not FDA-approved |
Which one patients tend to be offered
Clinics generally suggest PRP first for tendon problems and earlier-stage joint wear, because it is cheaper, the collection is trivial, and a course can be repeated. Stem cell protocols are more often proposed where cartilage loss is more advanced, or where a patient has already tried PRP without the result they wanted.
That is a pattern in how treatment is offered, not a statement that either works for a given condition. Evidence quality differs sharply between indications, and neither is a substitute for the diagnosis and advice of a licensed physician who has examined you.
Questions worth asking either way
Ask what exactly is being injected and where it came from. Ask how many times the clinic has treated your specific condition and what outcome it tracks. Ask whether imaging guidance is used. Ask what the total cost covers, including follow-up injections. And ask what the published evidence for your indication actually shows. A clinic that answers that one carefully is telling you something useful.
PRP vs stem cell therapy: common questions
Is stem cell therapy better than PRP?
Neither is universally better. They are different products used at different price points and, in practice, at different stages of joint degeneration. Which is appropriate, if either is, depends on your diagnosis, and that is a decision for a physician who has examined you and reviewed your imaging.
Why does stem cell therapy cost so much more?
Cost tracks the work involved. PRP needs a blood draw and a centrifuge. An autologous stem cell procedure adds a harvesting step (liposuction or a bone-marrow aspiration) plus cell processing, more staff time, and a longer appointment. Donor-tissue products carry the cost of the tissue itself.
Can you have PRP and stem cell therapy together?
Some clinics combine them, most often by adding PRP to a cell preparation in the same session. Whether that adds anything is not well established; ask the clinic what it charges for the combination and what evidence it is relying on.
Is either treatment covered by insurance?
In the United States, both are usually paid out of pocket. Most insurers classify PRP and stem cell injections for orthopedic use as investigational. Ask the clinic for the itemised cost in writing before you commit.
