Platelet-rich plasma concentrate to augment bone fusion.

Within the foot and ankle literature, there exists only a handful of basic science and clinical articles reporting on the efficacy and clinical utility of platelet-rich plasma (PRP). This article discusses the concept and basic science of PRP, and clinical applications of PRP for the augmentation of bone healing in foot and ankle surgery. The authors also provide a classification system that assesses relative risks for poor bone healing and the need for orthobiologic augmentation.
