Platelet-rich plasma (PRP) has been the subject of hundreds of publications in recent years. Reports of its effects in tissue, both positive and negative, have generated great interest in the orthopaedic community. Protocols for PRP preparation vary widely between authors and are often not well documented in the literature, making results difficult to compare or replicate. A classification system is needed to more accurately compare protocols and results and effectively group studies together for meta-analysis. Although some classification systems have been proposed, no single system takes into account the multitude of variables that determine the efficacy of PRP. In this article we propose a simple method for organizing and comparing results in the literature. The PAW classification system is based on 3 components: (1) the absolute number of Platelets, (2) the manner in which platelet Activation occurs, and (3) the presence or absence of White cells. By analyzing these 3 variables, we are able to accurately compare publications.
富血小板血浆（PRP）近年来已成为数百篇出版物的主题。关于其在组织中的作用的报告，无论是积极的还是消极的，都引起了矫形医学界的极大兴趣。PRP 制备方案在作者之间差异很大，并且在文献中常常没有很好地记录，这使得结果难以比较或复制。需要一个分类系统来更准确地比较方案和结果，并有效地将研究分组进行荟萃分析。虽然已经提出了一些分类系统，但没有一个系统考虑到决定 PRP 疗效的众多变量。在本文中，我们提出了一种简单的方法来组织和比较文献中的结果。PAW 分类系统基于 3 个组成部分：（1）血小板的绝对数量，（2）血小板激活发生的方式，以及（3）白细胞的存在或不存在。通过分析这 3 个变量，我们能够准确地比较出版物。
