May amplify activity at the transmembrane receptors.
Increase in vascular permeability
Derived from autologous blood with a high platelet concentration in a small volume of plasma.
Contains growth factors that act during the initial phase of healing and tissue regeneration.
Considered a minimally invasive, simple, and relatively low-cost procedure.
PRP products may differ in their method of preparation and numerous devices are commercially available.
Lack of clarity regarding the platelet concentration, the role of white blood cell filtering, the site of injection into the knee, and the number and frequency of injections for proper effectiveness.
