A Comparative Study Of Efficacy Of Intra-lesional Dry Needling, Platelet Rich Plasma And Corticosteroid In Lateral Epicondylitis
Background: Lateral epicondylitis (LE) or Tennis Elbow (TE) is a common cause of musculoskeletal pain involving common extensor origin of the forearm with various treatment options available ranging from conservative, intra-lesional injection to surgical.
Material & Methods: 147 cases of recalcitrant Lateral Epicondylitis treated with intra-lesional dry needling (n=50), platelet rich plasma (PRP) (n=49) or corticosteroid (n=48) injections were compared for VAS and DASH score.
Results: The mean pre-injection VAS score in needling, PRP and steroid group improved from 67.48, 68.00 and 67.39 to 38.50, 36.37 and 36.85 at 24 weeks’ post-injection respectively which was statistically significant (p<0.05). The mean pre-injection DASH score in needling, PRP and steroid group improved from 57.72, 56.96 and 56.19 to 32.04, 31.37 and 31.17 24 weeks’ post-injection respectively, which was statistically significant with paired t test p value < 0.05.
Conclusion: All three procedures, intra-lesional dry needling, PRP and corticosteroid were equally effective in treating lateral epicondylitis, with improvement in both the functional as well as pain scores in long term, but immediate post procedural relief was found better in the corticosteroid group.
