Autologous blood versus corticosteroid local injection for treatment of Lateral Epicondylosis: A Randomized Clinical Trial

Abstract

Objective: The objective of the present single blinded prospective randomized control trial was assessment of efficacy of autologous blood injection versus local steroid injection in treatment of lateral epicondylosis of elbow. Methodology: Using a pre-post experimental design, a total of sixty patients of previously untreated lateral epicondylosis were selected; Group 1 (n=30) was administered single injection of autologous blood and Group 2 (n=30) single local corticosteroid injection. Assessment was done at baseline, 2 weeks, 6 weeks and 12 weeks using PRTEE (Patient Rated Tennis Elbow Evaluation) score. Results: Pre injection parameters showed no difference between groups (chi square test, p > 0.005). Analysis between groups showed significant decrease in steroid group at very short term - 2 weeks (unpaired t test, p < 0.005).There was no difference between groups at 6 weeks. There was a significant improvement in blood group at medium term -12 weeks (unpaired t test, p < 0.05). Conclusion: Both the interventions were effective in reducing pain and improving functional status of patients in short term, but autologous blood was more effective in longer run.
