富血小板血浆及其在关节镜下前交叉韧带重建术中的应用研究进展

Research progress in platelet-rich plasma and its application in arthroscopic anterior cruciate ligament reconstruction

前交叉韧带损伤是膝关节常见的运动损伤,关节镜下前交叉韧带重建手术为其主要治疗方法。富血小板血浆具有促进组织愈合的作用,近年被广泛应用于临床。研究发现应用富血小板血浆在术中对前交叉韧带移植物进行处理或在术后进行关节腔内注射可以促进移植物的腱骨愈合并且可以加速膝关节损伤及其运动功能的恢复。现就富血小板血浆的成分、制备方法及其促进肌腱移植物腱骨愈合加速膝关节损伤和膝关节功能恢复的作用机制进行探讨。

Anterior cruciate ligament injury is a common sports injury in the knee joint,and arthroscopic anterior cruciate ligament reconstruction is the main treatment method.Platelet-rich plasma has the effect of promoting tissue healing and has been widely used in clinical practice in recent years.Research has found that the use of platelet-rich plasma for intraoperative treatment of anterior cruciate ligamen grafts or postoperative intra-articular injection can promote the tendon bone healing of the grafts and accelerate the recovery of knee joint injury and motor function.This article explores the components and preparation methods of platelet-rich plasma,and their mechanism of promoting thendon bone healing in tendon grafts and accelerating knee joint injury and knee function recovery.
