TOO YOUNG FOR THE OPERATION THEY OFFERED
They tell you a replacement lasts twenty years. You are fifty-four.
That arithmetic is the whole problem, and most people work it out in the parking lot afterward rather than in the room. It is also the optimistic 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
Lasting is not the same as being free of pain
The twenty-year figure describes the hardware, and 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 having a knee replaced. Where one is genuinely indicated we will establish that here first — the grade, the pain generator, what else is contributing — so the surgical conversation starts from a diagnosis rather than from a scan. It is the reason the arithmetic in the headline is the generous version, and the reason the timing of the operation should be yours. How the two options actually compare.
This is where the evidence is strongest
Symptomatic knee osteoarthritis that has not destroyed the joint is the best-studied indication for platelet-rich plasma and the one 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
Cartilage does not wear out like a brake pad
The mechanical story is the one everybody is given, and it is incomplete. A joint under load is also a joint being told, chemically, whether to repair or to give up. Two things usually decide that answer, and neither is visible on an X-ray.
- Insulin resistance and hyperinsulinaemia. A chronically elevated insulin signal shifts tissue toward storage and inflammation rather than 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 is endocrine tissue. It releases signaling molecules that keep cartilage and tendon in a degradative state regardless of how carefully you exercise.
- Sleep debt and the food environment. Repair happens overnight and depends on what you were given to build with. Neither is a lifestyle footnote; both change the biology the injection is asked to work in.
Under 7%
of the United States adult population is metabolically healthy on the criteria applied after 2021, down from under 12.2% in NHANES 2009–2016. The rest are carrying some degree of the inflammatory environment that decides whether an injured 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. Concentrating platelets into a joint that is chemically instructed 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
Quantities 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 made from how the tissue responds.
WHAT AN APPOINTMENT LOOKS LIKE
The day itself
- Consultation, imaging and bloodwork review. Candidacy is decided before anything is drawn. This is also where we look at the metabolic picture.
- Your blood is drawn and prepared here. Prepared in-house while you wait, to a stated protocol we will show you.
- Image-guided injection. Ultrasound or fluoroscopy. Placement is the variable that matters most and the one 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 you will need someone to drive you home.
WHO THIS IS NOT FOR
Who this is not for
Some people are not candidates, and 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 medications, which we check before the draw.
- Anyone looking for a single injection to substitute for the loading and rehabilitation that follows it.
Where a joint is far enough along that a replacement is what you actually need, we will say so — after establishing it, not instead of. Surgery is not part of the treatment 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 we 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 advice bolted on at the end. They are part of 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, decided by how the tissue responds rather than by a package. The assessment points.
Does it hurt?
Local anesthetic at the skin, and 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, but for a lower-limb injection arrange a ride. What to expect.
What is the difference between PRP and stem cells?
PRP contains no stem cells at all, and 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, and it is a reason to sequence rather than refuse. 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 and change the plan rather than repeat it. What we do next.
OPIOID STEWARDSHIP
Not a gestapo policy. Harm reduction in the context of human frailty
People arrive here having been managed one of two bad ways: left on an escalating dose nobody reviews, or cut off abruptly by a practice that decided the risk was theirs rather than the patient’s. Neither is stewardship.
For irreversible pain the goal is not zero opioids. It is the minimum effective exposure with function preserved and harm prevented — and interventional work exists partly to make that arithmetic better. An injection that reduces what a nervous system is demanding is a stewardship intervention 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, and 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.
