What Exactly Is Platelet-Rich Plasma?
PRP is a concentrated preparation of your own blood plasma that contains platelet concentrations 3 to 5 times higher than normal whole blood — along with the growth factors, cytokines, and bioactive proteins those platelets release when activated at a tissue repair site.
It is prepared from a small blood draw — typically 15 to 60 ml drawn from the patient's arm — that is processed in a centrifuge to separate the platelet-rich plasma layer from red blood cells and platelet-poor plasma. The concentrated PRP is then injected, under sterile technique, directly into the target tissue under guidance as appropriate.
Because PRP is derived from the patient's own blood, immune reaction risk is negligible. It delivers the biological repair signals the tissue naturally uses — concentrated and positioned exactly where the tissue needs them most — which is why it is particularly effective in low-vascularity structures like tendons and degenerated joint cartilage where natural healing signals are insufficient.
