Platelet-rich Plasma (PRP) Therapy: Research Suggests that Billions Matter

Platelet-rich plasma (PRP) therapy is increasingly recognized as a promising treatment for musculoskeletal disorders, including osteoarthritis, tendinopathy, and muscle injuries. Evolving evidence is quantifying the effective dose of platelets and which formulations work best.

Key takeaways

• Platelet dose matters: At least 3.5 billion per injection, 10-12 billion cumulative works best

• For joint injections: Leukocyte-poor PRP outperforms leukocyte-rich 

• Role in tendon and muscle repair remains uncertain 

• Red blood cell contamination and pre-activation reduce efficacy

Bottom line

Tailor PRP to condition and patient. Standardized prep and dosing guidelines are essential to unlock consistent results. Undoubtedly reimbursement will eventually require documentation on cell count and quality of PRP injection preparation.
