Platelet-Rich Plasma and Corticosteroid in the Treatment of Rotator Cuff Impingement Syndrome: Randomized Clinical Trial

Abstract

Abstract Objective This research aims to study the effectiveness of platelet-rich plasma (PRP) in the treatment of patients with rotator cuff impingement syndrome compared with the treatment with subacromial injection of corticosteroids. Methods This is a double-blind, randomized, comparative clinical trial. The patients were clinically evaluated with the use of the Disabilities of the Arm, Shoulder and Hand (DASH) outcome measure, University of California Los Angeles (UCLA) shoulder rating scale and Constant-Murley shoulder outcome score (CMS) on the day of application, and then again after 1, 3 and 6 months. Results No statistically significant differences were found (p < 0.05) when comparing the results of the DASH outcome measure, UCLA shoulder rating scale and CMS of the two groups at baseline and after 1, 3, and 6 months of treatment with subacromial injection. After the treatment, both groups showed a significant improvement in the DASH and UCLA scores (p < 0.05) when compared with the baseline. However, the CMS at 6 months after treatment with steroids was lower than the baseline. Concusions These findings suggest that PRP is a safe treatment and can be a useful tool in the therapeutic arsenal against of the rotator cuff diseases, for there was no significant difference between the subacromial use of PRP and corticosteroids.
