Comparative effectiveness of ultrasound-guided injection with either autologous platelet rich plasma or glucocorticoid for ultrasound-proven lateral epicondylitis: a three-arm randomised placebo-controlled trial

网球肘是影响男性和女性的常见疾病。它会造成疼痛、残疾、经常无法工作和高昂的医疗费用。最好的治疗是不确定的，但注射少量的一个人自己的富血小板血浆（PRP）似乎是一个有前途的新治疗方法，尚未得到适当的测试。我们将进行一项随机对照试验，以确定PRP注射的疗效、安全性和成本效益，看看它是否优于安慰剂或皮质类固醇注射。

Tennis elbow is a common condition affecting both men and women. It causes pain, disability, often inability to work and high health costs. The best treatment is uncertain but injection of a small quantity of a person’s own platelet rich plasma (PRP) appears to be a promising new treatment that has not yet been properly tested. We will perform a randomised, controlled trial to determine the efficacy, safety and cost-effectiveness of PRP injection to see if it is better than either placebo or corticosteroid injection.
