Effects of Platelet-rich Plasma Injection on Adhesive Capsulitis: An Interventional Case Series

Abstract

This case series aims to present effectiveness of PRP on pain, range of motion and functionality in patients with frozen shoulder and chronic shoulder pain The study included 9 patients (aged 18-75 years) who had shoulder pain for at least 3 months with 50% limited range of motion in at least one direction and VAS score>5. Under sonography guidance, PRP injection was performed into glenohumeral joint at baseline and on the week 2. Concurrently, PNF stretching and Codman exercises were given to all patients. Significant improvements were detected in VAS scores on week 2, 6, and 12 when compared to baseline(p<0.05) and SPADI scores in all time points when compared to baseline(p<0.05). There was significant improvement in active and passive ROM on weeks 2, 6 and 12 when compared to baseline(p<0.05). Treatment of adhesive capsulitis with PRP may be an alternative treatment method for patients.
