π¬ What is PRP?
Platelet-Rich Plasma (PRP) is a concentration of platelets derived from your own blood. These platelets are rich in growth factors that help repair tissues, reduce inflammation, and promote healing.
π Commonly used for:
- Knee osteoarthritis π¦΅
- Ligament injuries π€
- Tendon problems (like patellar tendinitis)
π§ͺ How PRP is Prepared
-
π©Έ Blood Collection
- About 10–30 ml of your blood is drawn.
-
βοΈ Centrifugation
- Blood is spun in a machine to separate:
- Red blood cells π΄
- Platelet-poor plasma π§
- Platelet-rich plasma π‘ (the useful part)
- Blood is spun in a machine to separate:
-
π PRP Extraction
- The concentrated PRP is collected in a syringe.
𦡠Injection Procedure (Step-by-Step)
-
π§Ό Preparation
- Skin over knee is cleaned with antiseptic.
- Sterile precautions maintained.
-
π§ Local Anesthesia (optional)
- Sometimes given to reduce pain.
-
π Injection
- PRP is injected into:
- Joint space (intra-articular) OR
- Around ligaments/tendons
- Often guided by ultrasound π‘ for accuracy.
- PRP is injected into:
-
π©Ή Post-injection
- Small dressing applied.
βοΈ Mechanism of Action
PRP works by releasing:
- 𧬠Growth factors (PDGF, TGF-β, VEGF)
- π Stimulates tissue repair
- π₯ Reduces inflammation
- π§± Promotes cartilage healing (limited but helpful)
π Indications
- 𦡠Early to moderate osteoarthritis
- π€ Ligament sprain (ACL, MCL)
- π Tendon injuries (jumper’s knee)
- π©Ή Chronic knee pain not responding to meds
π« Contraindications
- β Active infection
- β Blood disorders (low platelets)
- β Cancer in the area
- β Severe osteoarthritis (limited benefit)
π Benefits
- 𧬠Uses your own blood (low risk of reaction)
- π Reduces need for painkillers
- π οΈ Promotes natural healing
- β³ Long-lasting relief (months to years)
β οΈ Side Effects
- π Mild pain at injection site
- π΄ Swelling
- π‘ Temporary stiffness
- β οΈ Rare: infection
π§ Post-Procedure Care
- β Avoid heavy activity for 48–72 hrs
- π§ Ice packs for swelling
- π Avoid NSAIDs (they reduce PRP effect)
- π Gradual physiotherapy after a few days
π Number of Sessions
- Usually 1–3 injections
- Spaced 2–4 weeks apart
β³ Results & Recovery
- Improvement starts in 2–6 weeks
- Full benefit in 3–6 months
- Effect may last 6–18 months
π PRP vs Steroid Injection
| Feature | PRP 𧬠| Steroid π |
|---|---|---|
| Action | Healing | Pain suppression |
| Duration | Long-term β³ | Short-term β‘ |
| Side effects | Minimal | More with repeated use |
| Tissue repair | Yes β | No β |
π° Cost (India Approx)
-
βΉ4,000 – βΉ15,000 per injection πΈ
(depending on hospital & technique)
π§ Key Takeaway
π PRP is a regenerative therapy that helps the knee heal naturally rather than just masking pain. Best results are seen in early-stage joint problems.
