Comparison of Local Injection of Platelet Rich Plasma and Corticosteroids in the Treatment of Lateral Epicondylitis of Humerus

Abstract

Introduction: Lateral epicondylitis or Tennis Elbow is one of the most common causes of upper extremity pain with various treatment options. Platelet-rich plasma (PRP) offers a new option for the treatment of lateral epicondylitis. This study was conducted with an aim to compare the efficacy of PRP versus methyl-prednisolone local injection in patients with lateral epicondylitis. Materials and Methods: Sixty five patients with lateral epicondylitis were included in the study and randomized into two groups. Group A was treated with single injection of 1ml PRP with absolute platelet count of at least 1 million platelets/ mm3 . Group B was treated with single injection of 1ml (40mg) methylprednisolone. Pain, grip strength and functional improvements were assessed using visual analogue scale, dynamometer and quick Disabilities of the Arm, Shoulder and Hand scale respectively at baseline, 15 days, 1 month and 3 months. Results: Sixty patients completed the follow up. All assessment parameters improved significantly in both the Groups at each follow up compared to baseline. At the end of three months group A showed significantly better improvement as compared to Group B. Conclusion: PRP and methyl-prenisolone both are effective in the treatment of lateral epicondylitis. However, PRP is a superior treatment option for longer duration efficacy.
