Overview
About PRP Injection for Knee Pain
Platelet-Rich Plasma (PRP) is prepared by drawing a small amount of the patient's own blood and processing it in a centrifuge to concentrate the platelets and growth factors. When injected into the knee, these growth factors stimulate tissue repair, reduce inflammation, and improve joint environment. PRP is particularly effective for early to moderate knee osteoarthritis, tendon injuries, and chronic joint pain.

Uses your own blood — zero risk of allergic reaction or rejection
Stimulates natural tissue healing and cartilage protection
Reduces inflammation and joint pain with long-lasting effect
Minimally invasive OPD procedure — no surgery or hospital stay

Frequently Asked Questions
How is PRP prepared?
A small amount of blood (15–30 ml) is drawn from your vein. It is spun in a centrifuge for 10–15 minutes, which separates and concentrates the platelets. This concentrated PRP is then injected into the affected joint.
Is PRP injection painful?
There may be mild discomfort during the injection. The area may be slightly sore for 2–3 days after the procedure. A local anaesthetic can be used to minimise pain during injection.
How soon will I see results?
PRP takes 4–6 weeks to show full effect as it works by stimulating the body's natural healing process. Most patients notice significant improvement between 4–8 weeks.
How many PRP injections are needed?
A typical course is 1–3 injections given 4–6 weeks apart. The number depends on the severity of the condition. Maintenance injections can be given every 6–12 months.
Who is a good candidate for PRP?
PRP is ideal for patients with early to moderate knee osteoarthritis, tendon injuries (tennis elbow, plantar fasciitis, rotator cuff tendinopathy), or those who have not responded well to steroid injections.
