Recently PRP has been extensively explored as a chondro-protective treatment for symptomatic knee OA 8. Our study demonstrated that a dose of 10 billion platelets in 8 ml volume of PRP improves functional outcomes and protects the articular cartilage from further wear and tear in patients with knee OA.

In this work, we have reviewed current available evidence supporting the use of PRP derivatives to treat OA. At present, results from randomized clinical trials seem to favor PRP used over other IA treatments such as HA injections, to improve pain scales in …

PRP showed more improvement than HA in patient reported outcomes (PROs), including total WOMAC scores, in nine out of 12 high quality studies that reported that measure (Bansal 2021, Buendia -Lopez 2018, Lin 2019, Park 2021, Raeissadat 2020,

Platelet-rich plasma (PRP) has lately been investigated for the treatment of knee OA. This article reviews recent knowledge concerning PRP’s molecular mechanisms of action. The effectiveness of intra-articular PRP injections in the knee joint remains controversial, although most recent publications show pain alleviation in the short term.

This study evaluated the efficacy of intra-articular PRP injections on symptoms and joint structure in patients with knee OA. It was hypothesized that PRP would lead to greater improvements in knee pain severity and less medial tibial cartilage volume loss at 12 months compared with placebo saline injections.

2019年6月17日 · PRP 经 膝 关 节 腔 内 注 射 治 疗 膝 骨 关 节 炎( osteoarthritis，OA) 、关节软骨损伤、半月板损伤等， 近几年逐渐在临床上推广应用起来。 研 究 表 明， PRP 富含多种生长因子和炎症调节因子，具有保护 软骨细胞、促进软骨愈合 和减轻关节内炎症的作 用[26 － 28]。

Elvira等开展的1项随机对照试验（random controlled trial,RCT）研究（n＝55）比较了注射PRP与注射HA治疗K／L1、2、3级的膝OA患者的疗效，结果显示：两组均实现了疼痛的缓解，但在注射后3个月时PRP的效果明显。

2020年10月16日 · 富血小板血浆（platelet-rich plasma, PRP）是通过离心的方法从自体血中提取出来的血小板浓缩物，其最初被作为一种生物凝胶和屏障膜应用于临床。 1984 年Okuda等首先发现血浆中提取的富血小板血浆中含有多种生长因子。1997年Whitman和1998年的Marx率先将自体PRP应用于临床，将PRP与自体骨或异体骨相结合用于口腔颌面外科手术得到了良好的临床疗效。在随后的几年里，Camargo, Kim, Robiony，Anitua 等人的实验不断证明了PRP 不仅能加快骨 …
