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) methyl-prednisolone. 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.
