Comparison of the efficacy of corticosteroid, dry needling, and PRP application in lateral epicondylitis.

PURPOSE

The aim of this study was to compare the short-term efficacy of dry needling, corticosteroids, and platelet-rich plasma application (PRP) in the management of lateral epicondylitis.

METHODS

The study included 72 patients diagnosed with lateral epicondylitis divided into three groups of 24 individuals using the sealed envelope method. Group 1 underwent dry needling, Group 2 received 40 mg methylprednisolone acetate, and Group 3 received PRP treatment. Patients were assessed using the visual analog scale (VAS) and the Disabilities of the Shoulder, Arm, and Hand (DASH) score, and Jamar grip strength before treatment and 3rd week and 3rd month.

RESULTS

At the 3rd month, the mean VAS score was 1.16 ± 0.56 in dry needling group and 0.75 ± 0.60 in corticosteroids group, showing a statistically significant difference between dry needling and corticosteroids group, and between corticosteroids and PRP group (p = 0.015 and p = 0.000, respectively). At the 3rd week and 3rd month, VAS scores decreased in each treatment modality group, showing a statistically significant difference between the groups (p < 0.01). Jamar grip strength increased over time in all groups. There were no significant differences between the DASH scores of all groups at the 3rd week (p > 0.05). DASH scores decreased significantly from the 3rd week to the 3rd month in dry needling and corticosteroids group (p < 0.01), while it increased slightly in PRP group during the same period with a statistically insignificant change (p > 0.05). DASH scores decreased significantly at the 3rd month for all groups (p = 0.014).

CONCLUSION

Dry needling is an effective and safe application for the short-term treatment of lateral epicondylitis.
