PRP Injections in St. Louis
They tell you a replacement lasts twenty years. You are fifty-four.
PRP STL gives platelet-rich plasma (PRP) and other orthobiologic injections in St. Louis. Every injection is image-guided. We treat knee osteoarthritis and tendon problems. Knee osteoarthritis has the strongest evidence. We decide if you are a candidate at a consultation. It reviews your imaging and bloodwork before anything is drawn.
The math in that line is the whole problem. Most people work it out in the parking lot afterward, not in the room. It is also the hopeful version, because lasting is not the same as being free of pain. Waiting has a cost. So does going early.
WHERE YOU ARE ON THE SCALE
How bad is it on an ordinary day?
- Only after activity
- Most days, tolerable
- Every day, limiting
- Stairs and nights
Does a knee replacement stop the pain?
The twenty-year figure describes the hardware. The hardware mostly does last: about 96% of knee implants are still in place at ten years. What it does not describe is the person attached to it.
A quarter of replaced knees still hurt at one year. At roughly five years the figure is 28%. It does not fade the way people are told it will. 21% are still taking opioids twelve months after the operation. And a knee replaced between the ages of 46 and 50 carries a 22.4% lifetime risk of needing a second, larger operation.
None of that is an argument against a knee replacement. Where one is truly needed, we will establish that here first. We check the grade, the pain source and what else is adding to it. That way the surgery talk starts from a diagnosis, not from a scan. That is why the replacement math at the top of this page is the generous version. It is also why the timing of the operation should be yours. How the two options actually compare.
Where does PRP work best?
Knee osteoarthritis with symptoms, in a joint that is not destroyed, is the best-studied use of platelet-rich plasma. It is also where the trials are most encouraging.
WHAT THE DATA SUPPORTS
Knee osteoarthritis has better evidence than any other indication we offer. Others are weaker, and we will say which.
WHY IT STOPPED HEALING ON ITS OWN
Why does a joint stop healing on its own?
Everybody is given the mechanical story, and it is incomplete. A joint under load is also being told, by its chemistry, whether to repair or give up. Two things usually decide that answer. Neither shows up on an X-ray.
- Insulin resistance and hyperinsulinemia. Insulin that stays high pushes tissue toward storage and inflammation instead of repair. It is the single most common reason a joint stops responding to load the way it used to.
- Low-grade inflammatory load. Visceral fat (fat packed around the organs) is endocrine tissue, meaning it releases hormones. It sends out signals that keep cartilage and tendon breaking down, no matter how carefully you exercise.
- Sleep debt and the food environment. Repair happens overnight. It depends on what you were given to build with. Neither is a lifestyle footnote. Both change the biology the injection has to work in.
Under 7%
of the United States adult population is metabolically healthy on the criteria used after 2021, down from under 12.2% in NHANES 2009–2016. The rest carry some of the inflammatory environment that decides whether a hurt tendon or a worn joint can rebuild itself.
This is why we ask about your sleep and your bloodwork before we ask about your knee. Packing platelets into a joint that is chemically told not to heal is an expensive way to be disappointed.
What we use
IMAGE-GUIDED, EVERY TIME
- Platelet-rich plasma
- Bone marrow aspirate concentrate
- Prolotherapy
- Knee osteoarthritis
- Tendon and enthesis problems
- How we choose between them
Amounts are clinical decisions, not a package. There is no magic in a series of three, and we do not sell one. Intervals are a scheduling fact. How many injections you need is a judgment based on how the tissue responds.
WHAT AN APPOINTMENT LOOKS LIKE
What happens at a PRP appointment?
- Consultation, imaging and bloodwork review. We decide if you are a candidate before anything is drawn. This is also where we look at the metabolic picture.
- Your blood is drawn and prepared here. We prepare it in-house while you wait, to a stated protocol we will show you.
- Image-guided injection. Ultrasound or fluoroscopy. Placement matters most, and it is the step most often skipped.
- Loading, then rehabilitation. The tissue needs a stimulus afterward. This part is not optional, and it is not an afterthought.
No sedation is used. Recovery is two to four hours, and most patients drive themselves home.
WHO THIS IS NOT FOR
Who this is not for
Some people are not candidates. Being told so at the consultation is the point of having one.
- An active infection anywhere, and particularly in the joint being considered.
- A joint that has already lost most of its cartilage, if what you want back is the cartilage.
- Certain blood and platelet disorders, and some current medicines. We check these before the draw.
- Anyone looking for one injection to replace the loading and rehab that follows it.
Some joints are far enough along that a replacement is what you actually need. Then we will say so, after we establish it, not instead of it. Surgery is not part of the plan for early joint disease. But it is the right plan for some of the people who ask us about this.
THE METABOLIC PICTURE
Why does a PRP clinic ask about your bloodwork?
“I spent twenty years telling patients their A1C was not too bad. I was wrong, and the physiology is what changed my mind.”
That correction is why an orthobiologic consultation here does not stop at the joint. Insulin resistance, sleep debt and the food environment are not lifestyle tips tacked on at the end. They help decide whether the injection has anything to work with.

ACCESS
How far you are from us
Routed free-flow from the clinic, not estimated from a radius. The full service area.
What people ask before they book
How many injections will I need?
Commonly one to three. How the tissue responds decides it, not a package. The assessment points.
Does it hurt?
Local anesthetic at the skin. It varies sharply by site. What the visit involves.
How long before I know whether it worked?
Six weeks for a first signal, three months for the honest answer. Recovery timeline.
Can I drive myself home?
No sedation is used, and most patients drive themselves home. Arrange a ride only if a lower-limb injection leaves your leg temporarily weak or numb. What to expect.
What is the difference between PRP and stem cells?
PRP contains no stem cells at all. Most “stem cell” offers are something else again. What the phrase covers.
Will it work if I am carrying extra weight?
It changes the odds through inflammation and insulin signaling, not through load alone. It is a reason to sequence care, not to refuse it. How we assess.
Am I too old for this?
Age matters less than stage and metabolic terrain. Candidacy.
Is it covered by insurance?
No. This is a self-pay practice, and we do not bill insurance. Why.
What happens if it does not work?
We say so at three months. Then we change the plan instead of repeating it. What we do next.
What is the downside of PRP injections?
The downsides are mostly practical. It is slow: six weeks for a first signal and three months for the honest answer. It will not give back cartilage a joint has already lost. It is not for anyone with an active infection or certain blood and platelet disorders. It is not covered by insurance, because this is a self-pay practice. And if it has not worked at three months, we say so and change the plan.
Are PRP injections worth the money?
It depends on the joint and on the body around it. Knee osteoarthritis that has not destroyed the joint has better evidence than any other use we offer. Others are weaker, and we will say which. We also check insulin resistance, sleep and inflammation first. That is because platelets placed in a joint that is chemically told not to heal are an expensive way to be disappointed.
Is there anything better than PRP?
Sometimes. PRP is one of three injections we use, with bone marrow aspirate concentrate and prolotherapy. The choice follows the tissue in front of us. For a joint that is far enough along, a replacement is the right plan. We will say so once we have established it. Whichever injection is used, the loading and rehab afterward are part of the treatment, not an afterthought.
OPIOID STEWARDSHIP
Not a gestapo policy. Harm reduction in the context of human frailty
People arrive here after being managed one of two bad ways. Some were left on a rising dose nobody reviews. Others were cut off suddenly by a practice that decided the risk was theirs, not the patient’s. Neither is stewardship.
For pain that will not reverse, the goal is not zero opioids. It is the lowest dose that works, with function kept and harm prevented. Interventional work exists partly to make that math better. An injection that lowers what a nervous system is demanding is a stewardship step as much as a pain one.
WHEN YOU WANT TO TALK ABOUT TREATMENT
If you are close to needing the operation, we will say so
If the honest answer is that you are close to needing the operation, we will tell you that too. Tell us which joint and how long. We will tell you whether this is worth your time.
Find out whether you are a candidate
Whether PRP is reasonable for you depends on your tissue, your metabolic health and what you have already tried. That is a conversation, not a form.
