Platelet Dose, Concentration, and Injectate Volume in Platelet-Rich Plasma Therapy: An Evidence-Informed Review of Large-Joint Osteoarthritis
In knee OA, the available literature shows a dose-related signal at approximately 5 billion platelets or greater per injection, while hip studies report measured protocols around 6–7 billion platelets per injection, while Glenohumeral evidence remains insufficient for dose-specific conclusions.
