Platelet-rich plasma sounds futuristic, but the principle is old and simple: your blood already carries the repair crew your body uses to heal. PRP just concentrates that crew and delivers it where you need it. Here's the straight explanation of the science, the uses, and what the evidence does and doesn't support.
The science, in plain terms
Your platelets do more than help blood clot — they release growth factors that signal tissue to repair itself. In a PRP procedure, a small amount of your blood is drawn and spun in a centrifuge to separate and concentrate those platelets. The concentrated plasma is then injected into the injured area, delivering a stronger dose of your own healing signals than the body would send on its own.
What it's used for
- Mild to moderate knee osteoarthritis and joint pain
- Tendon problems like tennis elbow and Achilles tendinopathy
- Shoulder, hip, and other persistent soft-tissue issues
- Plantar fasciitis that hasn't responded to conservative care
- Hair restoration for early-stage thinning
What the evidence supports — and where it's mixed
The honest picture: PRP shows the most promising results for certain tendon conditions and mild knee arthritis, while evidence for other uses is more variable. It is not a guaranteed fix, and it works better as one option among several than as a miracle cure. A good provider will tell you when PRP is a reasonable next step and when it isn't.
What recovery looks like
The procedure is in-office and uses only your own biology, so there's no general anesthesia. Most people return to normal activity within a day or two and notice gradual improvement over several weeks as healing progresses, sometimes across more than one session.
