Ultrasound guided platelet-rich plasma injection for the treatment of rotator cuff tendinopathy

Background: Degenerative changes and inflammation in the rotator cuff (RC) are the most important causes of shoulder pain. The aim of the present study was to determine the effectiveness of platelet-rich plasma (PRP) in patients with chronic RC tendinopathy. Materials and Methods: This study was an open-label study performed at Kashani Hospital between April 2012 and June 2014. Patients with a Results: A total number of 17 patients were enrolled. The mean of CSS before and after intervention was 37.05 ± 11.03 and 61.76 ± 14.75, respectively ( P P = 0.45, r = 0.03). Significant relation was observed between the individuals' age and improvement of CSS ( P = 0.02, r = −0.49). There was no significant difference in CSS improvement between genders ( P = 0.23). Conclusion: Single injection of PRP is effective to reduce pain and improve range of motion in patients with bursal side partial tearing of RC who failed to respond to conservative treatments.
