Platelet Rich Plasma Therapy: Process and What to Expect

Understanding the Platelet Rich Plasma Therapy

The process of PRP therapy begins with a simple blood draw from your arm. A 30-millilitre venous blood sample holds approximately 3-5 millilitres of concentrated PRP, depending on your baseline platelet count. The blood collection uses anticoagulants like citrate dextrose A (a sterile chemical solution) to prevent clotting.

The preparation process involves differential centrifugation, a technique that separates cellular components based on specific gravity. During the first centrifugation spin, your blood separates into three distinct layers: red blood cells at the bottom, a middle layer containing platelets and white blood cells, and platelet-poor plasma at the top. Technicians carefully transfer the upper layers to a sterile tube for the second centrifugation. This second spin concentrates platelets into a small plasma volume, creating the therapeutic PRP solution.

Research shows that first-spin settings of 900 grams for 5 minutes, followed by second-spin settings of 1000 grams for 10 minutes at 16°C, constantly give platelet concentrations exceeding 1 million per millilitre [2]. Temperature control during processing proves critical; maintaining 12-16°C prevents unintended platelet activation.

How Does Platelet Rich Plasma Therapy Work at the Cellular Level?

Your platelets contain more than 30 bioactive proteins essential for tissue healing. Seven fundamental growth factors actively secreted by platelets initiate all wound healing processes: platelet-derived growth factor (PDGF), transforming growth factor-beta (TGF-β), vascular endothelial growth factor (VEGF), fibroblast growth factor (FGF), hepatocyte growth factor, epidermal growth factor, and insulin-like growth factor (IGF).

When exogenous activators activate PRP during injection, platelets aggregate and coagulate within the target tissue. Within 10 minutes, degranulation begins (the process in which platelet granules fuse with cell membranes, releasing bioactive proteins). Within one hour, nearly 95% of pre-synthesised growth factors are secreted into surrounding tissues.

These growth factors bind to transmembrane receptors on target cells, including mesenchymal stem cells, osteoblasts, fibroblasts, endothelial cells, and epidermal cells. This binding activates intracellular signal proteins that trigger gene expression, directing cellular proliferation, matrix formation, collagen synthesis, and tissue regeneration. TGF-β specifically inhibits inflammatory cytokines that interfere with chondrocytes while preventing cell death. PDGF promotes osteoblast proliferation and enhances collagen synthesis.

Platelet Rich Plasma Therapy Applications in India

Indian patients increasingly access PRP treatment for musculoskeletal conditions, particularly knee osteoarthritis affecting millions across the country. Clinical evidence demonstrates that PRP injections effectively improve pain scores, functional activity, and quality of life in Indian patient populations.

The treatment addresses the following conditions:

• Knee osteoarthritis with significant pain reduction and improved mobility
• Shoulder injuries including rotator cuff tendinopathy and impingement syndrome
• Plantar fasciitis causing heel pain and walking difficulties
• Lateral epicondylitis (tennis elbow) affecting work capacity
• Hip osteoarthritis in ageing populations
• Temporomandibular joint disorders affecting jaw function

Indian healthcare facilities now standardise PRP preparation protocols, ensuring constant platelet yields and therapeutic outcomes.

PRP Treatment Cost Considerations

PRP treatment cost in India varies based on geographic location, facility type, and treatment complexity. Urban centres typically charge between ₹15,000 and ₹50,000 per injection, with most treatment courses requiring 2-3 injections. Rural areas may offer more affordable options, though facility quality varies considerably.

Common cost factors include the following:

• Blood collection and processing expenses
• Centrifuge equipment and maintenance
• Physician expertise and ultrasound guidance
• Facility overhead and sterilisation protocols
• Number of injections required
• Additional treatments combined with PRP

Many Indian patients find PRP treatment cost-effective compared to surgical interventions, which often exceed ₹100,000-300,000 with extended recovery periods.

Platelet-Rich Plasma Therapy: Preparation Methods

Standardising PRP preparation proves essential for consistent therapeutic outcomes. Two primary preparation methods exist: the PRP method and the buffy coat method. The PRP method involves two centrifugation spins, producing pure platelet-rich plasma with minimal white blood cells. The buffy coat method uses high-speed centrifugation to collect the middle layer containing both platelets and white blood cells.

Leukocyte-poor PRP (LP-PRP) preparations contain high platelet concentrations with minimal white blood cells. Research demonstrates LP-PRP superiority for pain relief in osteoarthritis patients. Leukocyte-rich PRP (LR-PRP) contains both platelets and white blood cells and may trigger more acute inflammatory responses.

Centrifugation parameters critically influence final PRP composition. Relative centrifugal force (RCF) measured in gravitational units (g), centrifugation duration, and temperature all affect platelet recovery and growth factor concentration. Optimal protocols achieve 70-80% platelet recovery while maintaining platelet viability and integrity.

Anticoagulant selection impacts PRP quality. Citrate dextrose A and trisodium citrate preserve platelet functionality better than EDTA, which can damage platelet membranes. Proper anticoagulant concentration prevents premature clotting while maintaining optimal pH and calcium levels for platelet activation.

Platelet-Rich Plasma Therapy Effectiveness

Clinical evidence strongly supports the effectiveness of PRP therapy for multiple conditions. A meta-analysis of 24 randomised controlled trials found that PRP injections significantly reduced pain in knee, ankle, and temporomandibular joint osteoarthritis compared with control treatments. Pain scores improved by about 1.0-1.4 points on visual analogue scales [3].

Functional improvement metrics show substantial benefits. Knee Injury and Osteoarthritis Outcome Score (KOOS) assessments reveal significant improvements in pain symptoms, activities of daily living, and quality of life following PRP treatment.

Multiple injections prove more effective than single injections. Treatment protocols involving 2-3 injections spaced 2-3 weeks apart produce better outcomes than single-injection approaches. This sequential treatment allows sustained growth factor delivery and progressive tissue remodelling.

Long-term effectiveness extends beyond initial treatment periods. Many patients maintain functional improvements for 6-12 months following treatment completion.
