Who PRP Tends to Help
PRP is worth discussing if you recognize yourself in most of this:
If your knee is bone on bone, if it has been giving out on you, or if pain is keeping you up most nights, PRP is not likely to be the answer and we will say so. It is also worth knowing up front that PRP is typically not covered by insurance, which makes it a different kind of decision from the ones your plan pays for.
The gap between therapy and replacement is real, and it is where most people get stuck.
There is a long stretch between a knee that therapy can manage and a knee that needs replacing. It can last years. During it you are usually told to keep doing what you are doing and come back when it gets worse, which is not much of a plan when the knee is already shaping your life.
PRP, short for platelet rich plasma, is one of the things that can fill that gap. A small amount of your own blood is drawn and spun to concentrate the platelets, and that concentrate is injected into the knee. Here is something to consider: PRP is prepared from your own blood and is not an FDA-approved treatment for knee arthritis. The research is genuinely mixed. Some studies find meaningful relief for earlier arthritis, others find little difference, and preparation methods vary enough between clinics that the studies are hard to compare. Anyone telling you it is proven, or that it rebuilds cartilage, is making claims the evidence doesn’t fully support.
What we can say is what it is reasonably used for. PRP therapy for the knee aims to reduce pain and improve how the joint feels for a period of time. It does not reverse arthritis and it does not remove the possibility of needing a replacement later. For the right knee it can buy comfortable time, and for some people that time is worth a lot. For the wrong knee it is money and hope spent on the wrong thing, which is why the conversation comes before the injection.
What a PRP Appointment Actually Involves
This is an office visit, not surgery. You drive yourself home.
The Visit
Blood is drawn from your arm the way it would be for any lab test, then spun to separate and concentrate the platelets. The concentrate is injected into the knee. You are in the office rather than an operating room, and you go about your day afterward.
The First Few Days
The knee is often sore and sometimes more swollen than usual at first, which is expected rather than a sign something went wrong. You are asked to take it easy, and to avoid anti-inflammatory medication unless told otherwise.
The Weeks After
PRP does not work immediately. If it helps, the change tends to come on gradually over weeks rather than days. Whether more than one injection is recommended depends on how your knee responds to the first, and that gets decided at follow-up rather than booked in advance.
