Your doctor has recommended PRP. Or you have heard about it. What exactly is it? Is it just a trend — or does it actually work? This guide explains PRP therapy in simple, honest language — including who it helps and who it does not.
Causes and what is happening inside your body
PRP stands for Platelet-Rich Plasma. Your blood contains platelets — tiny cells that carry growth factors. These growth factors are your body's natural repair signals. In PRP therapy, we draw a small amount of your blood, spin it in a centrifuge machine to concentrate the platelets 5-7 times, and inject this concentrated solution directly into the damaged joint or tendon. The growth factors then activate the body's healing response — reducing inflammation, stimulating cartilage repair and promoting tissue regeneration.
🧬 Simple way to understand it: PRP is not a medicine. It is your own blood — concentrated and redirected to exactly where healing is needed most.
How to recognise this condition — and when to see a doctor urgently
⚠️ See a doctor urgently if: You have active joint infection · You have blood cancer or clotting disorder · You are on blood thinners — always inform Dr. Sumit
What you can do to reduce your risk and protect yourself
Treatment options from simple home care to specialist treatment
The PRP procedure takes about 45-60 minutes. Blood is drawn from your arm, spun in the centrifuge, and injected under ultrasound guidance. You can go home the same day. Expect mild soreness for 2-3 days — this is normal and shows healing is happening. Results appear gradually from 4-8 weeks. Most patients need 3 injections for knee OA, spaced 4-6 weeks apart. Effects typically last 12-18 months.
💡 PRP vs Cortisone: Cortisone gives quick pain relief but damages cartilage with repeated use. PRP takes longer to work but repairs tissue and is safe to repeat. Most studies show PRP superior to cortisone at 12 months.
What I tell every patient who comes to me with this condition
"I have seen patients cry with relief after PRP — people who had given up on the idea of living without pain. But I have also told patients honestly that PRP cannot help them — that they need surgery. What matters most is giving every patient the correct information and the right treatment, not just the popular one."
