Abstract

Introduction: Platelet-rich plasma (PRP) is effective for knee osteoarthritis (OA) and certain tendinopathies. Current recommendations support the use of leukocyte-poor PRP for OA and leukocyte-rich PRP for tendinopathy. If a patient presents with both OA and tendinopathy, very few systems can create multiple PRP products in the same treatment session. The Angel device processes multiple cycles to produce different PRP products. Methods: Ten healthy volunteers donated 156 mL whole blood (WB) that was mixed with 24 mL of anticoagulant citrate dextrose solution, solution A. The first PRP was produced by processing 120 mL at the 0% hematocrit setting and the second PRP was created by processing the remaining 60 mL at the 15% hematocrit setting. WB and PRP underwent complete blood counts and growth-factor analysis. Results: Ten patients donated WB for processing. The 0% setting yielded 3.7 ± 0.15 mL PRP, whereas the 15% setting produced 4.7 ± 0.33 mL. The 0% and 15% settings both concentrated platelets significantly more than WB (1101.5 ± 281.7 K/uL and 1357.8 ± 363.7 vs 184.3 ± 39.1 K/uL, P = 0.000). The 0% setting reduced total leukocytes, but this was not statistically significant. The 15% setting concentrated total leukocytes to 24 ± 8.72 K/uL, which was significantly higher than WB (P = 0.000). Neutrophil concentration was significantly reduced in the 0% PRP compared with 15% (0.032 ± .02 vs 6.75 ± 5.76 K/uL, P = 0.000). Discussion: Two unique PRP products were created from the same batch of WB using a single commercial kit by processing aliquots at different settings.
用单一处理试剂盒从单批全血中生成2种独特的富血小板血浆产品
富血小板血浆(PRP)对膝关节骨关节炎(OA)和某些肌腱病变有效。目前的建议支持使用白细胞含量低的PRP治疗OA,而白细胞含量高的PRP治疗肌腱病变。如果患者同时患有骨性关节炎和肌腱病变,很少有系统可以在同一疗程中产生多种PRP产品。Angel设备处理多个循环以生产不同的PRP产品。方法:10名健康志愿者捐献156 mL全血(WB),与24 mL抗凝柠檬酸葡萄糖溶液a溶液混合,在0%血细胞比容下处理120 mL产生第一次PRP,在15%血细胞比容下处理其余60 mL产生第二次PRP。WB和PRP进行全血细胞计数和生长因子分析。结果:10例患者捐献WB用于处理。0%的PRP浓度为3.7±0.15 mL,而15%的PRP浓度为4.7±0.33 mL。0%和15%的PRP浓度均显著高于WB浓度(1101.5±281.7 K/uL和1357.8±363.7 vs 184.3±39.1 K/uL, P = 0.000)。0%的设置减少了白细胞总数,但这没有统计学意义。15%组总白细胞浓度为24±8.72 K/uL,显著高于对照组(P = 0.000)。中性粒细胞浓度在0% PRP组显著低于15% PRP组(0.032±0.02 vs 6.75±5.76 K/uL, P = 0.000)。讨论:两种独特的PRP产品是通过在不同的设置下处理相同的配额,使用单一的商业试剂盒从同一批WB中创建的。

期刊介绍: The purpose of Techniques in Orthopaedics is to provide information on the latest orthopaedic procedure as they are devised and used by top orthopaedic surgeons. The approach is technique-oriented, covering operations, manipulations, and instruments being developed and applied in such as arthroscopy, arthroplasty, and trauma. Each issue is guest-edited by an expert in the field and devoted to a single topic.
