The Science of PRP: Growth Factors and Tissue Repair
Platelets are small blood cells best known for their role in clotting — but they contain far more than clotting factors. Each platelet is packed with alpha granules containing a concentrated payload of growth factors that orchestrate the body's tissue repair cascade. When platelets are activated at an injury site, they release these growth factors to recruit stem cells, stimulate collagen synthesis, promote angiogenesis (new blood vessel formation), and suppress chronic inflammation.
The key growth factors in PRP include Platelet-Derived Growth Factor (PDGF), Vascular Endothelial Growth Factor (VEGF), Transforming Growth Factor-Beta (TGF-β), Epidermal Growth Factor (EGF), and Insulin-Like Growth Factor (IGF-1). Together, these compounds create a powerful anabolic environment that accelerates healing in tissues with naturally poor blood supply — tendons, cartilage, and ligaments — where the body's repair capacity is inherently limited.
By concentrating platelets 5–10× above baseline whole blood levels and delivering them precisely to the injury site, PRP therapy amplifies the natural healing response far beyond what the body can achieve on its own.
Conditions Treated with PRP Therapy
Tendinopathy & Tendon Tears
Rotator cuff, Achilles, patellar, and lateral epicondyle (tennis elbow) tendinopathy respond well to PRP — stimulating collagen remodeling in chronically degenerated tendon tissue.
Osteoarthritis
PRP reduces inflammatory cytokines within arthritic joints, stimulates cartilage matrix production, and slows degenerative progression — providing pain relief and functional improvement.
Ligament Injuries
Partial ligament tears and chronic ligament laxity (knee, ankle, SI joint) benefit from PRP's ability to stimulate fibroblast proliferation and collagen cross-linking.
Disc Degeneration
Intradiscal PRP injections show promise for stimulating nucleus pulposus cell regeneration and reducing the inflammatory environment that drives discogenic pain.
Muscle Injuries
Muscle tears and chronic myofascial injuries respond to PRP's anabolic and anti-inflammatory effects — accelerating satellite cell activation and muscle fiber repair.
Post-Surgical Healing
PRP applied at surgical sites or injected post-operatively accelerates tissue healing, reduces scar formation, and shortens recovery timelines.
The PRP Procedure: Step by Step
Blood Draw
A small amount of blood (30–60 mL) is drawn from your arm — similar to a standard blood test.
Centrifugation
The blood is placed in a specialized centrifuge that spins at high speed, separating platelets from red blood cells and plasma. This process takes approximately 15 minutes and produces a concentrated platelet-rich plasma.
Activation & Preparation
The PRP is prepared according to your specific condition — leukocyte-rich or leukocyte-poor formulation, concentration level, and activation method are customized to optimize outcomes for your tissue type.
Image-Guided Injection
Under ultrasound or fluoroscopic guidance, the PRP concentrate is injected precisely into the target tissue — tendon, joint, ligament, or disc. Imaging ensures accurate placement and maximizes therapeutic effect.
Recovery & Rehabilitation
Most patients resume normal activities within 24–48 hours. Physical therapy is coordinated to begin 2–4 weeks post-injection, capitalizing on the anabolic window created by PRP to rebuild strength and function.
