LINDBERGH TO I-170
Frontenac patients reach our PRP and orthobiologic clinic in around nineteen minutes, north on Lindbergh and east on I-170. The first cortisone injection worked well, and the third barely did anything. That pattern is not in your head, and it is not tolerance.
Getting here from Frontenac
Lindbergh north to I-170, then east to Natural Bridge Road — around nineteen minutes. Ground-floor entrance, parking outside.
Why do cortisone shots stop working?
A corticosteroid suppresses the inflammatory part of a problem without touching whatever is causing it. Where inflammation was doing most of the work, the first injection is impressive. As the degeneration underneath gets worse, there is less and less inflammation left to suppress.
So the shrinking benefit is not a failure of the drug. It is the drug doing exactly what it does while the real problem goes on. The gap between injections getting shorter is the clearest sign that something else is needed.
PRP versus cortisone sets the two side by side without pretending either is a cure.
Are repeated cortisone shots bad for your joints?
Repeated corticosteroid shots into a joint have a measurable harmful effect on cartilage over time. Repeated shots around a tendon weaken it. For a joint that needs to last decades, that trade deserves to be stated up front, not discovered later.
It does not make cortisone wrong. It makes an endless series of it wrong, especially in someone who is being told there is nothing else available.
Timing around an operation
Where surgery is likely within a year, the useful question is whether the tissue can be improved first. It is not whether an injection avoids the operation.
That is an under-used and legitimate role. It is a different conversation from the one most people expect to have.
What we do in the meantime
Between diagnosis and any procedure there is usually something worth changing — load, footwear, a specific strength gap. It is not filler.
Patients who make those changes respond better to whatever follows. That finding is consistent enough across the research to be worth acting on.
What we measure before and after
Range, strength and one specific task chosen because it matters to you. Recorded at the start, so progress is a measurement, not an impression.
Satisfaction scores are easy to collect and tell you very little. A joint that has regained twenty degrees is a fact.
What does the arthritis grade on my X-ray report mean?
Joint changes are usually graded from a plain X-ray, and that number drives decisions. Yet it matches symptoms poorly. People with severe grades walk comfortably. People with mild ones are in real trouble.
It describes how the joint looks, not how you live with it. Treatment built on the grade alone is built on the wrong variable.
When is surgery the better option?
For most of what we see, it is not. Early and moderate arthritis, stalled tendons and partial tears are treated here without an operation, and even a joint with little cartilage left gains time and a lower medication load from PRP. Surgery is the better option for a mechanically unstable joint or a large full-thickness tear in the right patient, and replacement remains the operation that restores a joint with no cartilage left.
PRP versus surgery sets out where each belongs, without presenting one as always better.
Timing, if surgery is coming anyway
Where an operation is likely within a year, the useful question is whether the tissue can be put in a better state first. It is not whether an injection can avoid it.
That is a legitimate and under-used role. It is a different conversation from the one most people expect.
How is PRP different from a cortisone shot?
An orthobiologic aims to trigger repair, not to suppress a signal. That is a different mechanism with a different timeline. It takes weeks to months, not days, and it is judged over that span, not at two weeks.
It does not replace cortisone in every case. When an acute (recent) inflammatory flare needs to settle fast, a steroid still does that better than anything else.
Deciding between them properly
The question is what stage the tissue is at, and what the joint needs to do for how long. Take a seventy-five-year-old wanting comfort for one event. Now take a fifty-year-old protecting a joint for thirty years. Those are different problems with different answers.
Hyaluronic acid is the third option that gets grouped in. It works by a different mechanism again.
The ceiling nobody measures
When a joint keeps flaring despite sensible treatment, body-wide inflammation is a likelier cause than bad luck, and it can be measured. The metabolic side explains what we test.
What gets measured, and when
A treatment with no measurement is hard to judge honestly. That is because memory of pain drifts, and both patient and physician want the answer to be good.
So a baseline is recorded before anything is injected. It includes a validated score for that joint, a walking or loading measure where one applies, and the specific activities you have stopped doing. Those are the things checked again afterward. The re-checks are timed to the biology, not the calendar. There is a first look at around six weeks, and a more meaningful one at three months, because tissue responses of this kind do not show themselves in two weeks.
If the three-month numbers have not moved, that is the answer. We say so, instead of proposing another injection on the theory that it needs longer. Being willing to call something a failure is what makes the successes worth anything.
Frequently asked questions about PRP near Frontenac
Why did my injection stop working?
Because it suppressed inflammation while the problem underneath got worse. Shorter gaps between shots are the signal: the comparison.
Is cortisone harmful?
Repeatedly, to cartilage and tendon, yes. Used now and then for a clear reason, it is still useful. The problem is the endless series.
How long before an orthobiologic works?
Weeks to months, not days. Judging it at two weeks is the most common reason a working treatment gets dropped: the timeline.
How far is it from Frontenac?
Around nineteen minutes via Lindbergh and I-170.
Is cortisone ever the better choice?
Yes. When an acute (recent) inflammatory flare needs to settle fast, a steroid still does that better than anything else. Used now and then for a clear reason, cortisone is still useful. What we steer people away from is an open-ended series of it. That goes double for someone who has been told there is nothing else available.
How do you decide between PRP, cortisone and hyaluronic acid?
By the stage the tissue is at, and what the joint needs to do, for how long. A seventy-five-year-old who wants comfort for one event and a fifty-year-old protecting a joint for thirty years are different problems with different answers. Hyaluronic acid is the third option people group in, and it works by a different mechanism again.
Can an injection help if I am having surgery anyway?
It can have a role. When an operation is likely within a year, the useful question is whether the tissue can be put in a better state before surgery. It is not whether an injection can avoid it. That is a legitimate and under-used reason to treat. It is a different conversation from the one most people expect to have.
How will I know if the treatment worked?
We record a baseline before anything is injected. It includes a validated score for the joint, a walking or loading measure where one applies, and the activities you have stopped doing. Those are checked again at around six weeks, and more meaningfully at three months. If the three-month numbers have not moved, we tell you and change the plan, rather than offering another injection on the theory that it needs longer.
