Abstract


Introduction: Rotator cuff tendinopathy is one of the most common cause of chronic shoulder pain and disability.

Aim: To compare the efficacy of PRP injection versus corticosteroid injection in the treatment of Supraspinatus tendinopathy.

Design: Prospective randomized study.

Methods: 100 patients with Supraspinatus tendinopathy were randomized into two groups of 50 each. Group A received subacromial corticosteroid injection while group B received Platelet rich plasma injection. Treatment outcomes were assessed at 2weeks, 6weeks and 3months following injection using CMS, VAS and SPADI scores.

Results: Reduction in pain and improvement in functional scores were evident in both the groups at each follow up, as assessed by VAS, Constant and SPADI scores. Mean VAS scores were significantly better in Corticosteroid group at 2 weeks(p=0.003) and  in PRP group at 3 months(p=0.037) following injection. . Constant score (CMS) showed better percentage improvement  with  Corticosteroid injection than the PRP injection at 2 weeks (p<0.0001) and 6 weeks (0.004) but not at 3 months (p=0.093). Mean SPADI scores were non-significant in both the groups at each follow ups.

Conclusion: Corticosteroid injection is better in short term relief but in long term  term both PRP and steroid had similar effects.
