The aim of the study was to compare the effects of single intra-articular platelet-rich plasma (PRP) and corticosteroid (CS) injections in patients with adhesive capsulitis of the shoulder.
Patients aged 18–70 yrs of either sex, diagnosed with adhesive capsulitis of shoulder, with less than 6-mo duration, were included. In intra-articular corticosteroid (IA-CS, control) group, 30 patients received a single injection (4 ml) of IA-CS and in IA-PRP (test) group, 30 patients received single IA-PRP injection (4 ml) into the glenohumeral joint under ultrasound guidance. All patients were prospectively followed for 12 wks.
Twenty-eight patients in IA-PRP group and 27 in IA-CS group finished the entire 12-wk study period. At 12 wks, decrements in visual analog scale and total shoulder pain and disability index scores, in IA-PRP group, were 58.4 and 55.1, compared with 48.7 and 45.8 in IA-CS group. In range of movement, IA-PRP group showed significant improvement in passive abduction (−50.4 vs. −39.4), internal (−36.8 vs. −25.8), and external rotations (−35.4 vs. −25.9) compared with IA-CS group, respectively. No major complications were observed in any patients.
At 12-wk follow-up, a single dose of IA-PRP injection was found to be more effective than an IA-CS injection, in terms of improving pain, disability, and shoulder range of movement in patients with adhesive capsulitis of the shoulder.
