Clinical and radiological comparison of effects of platelet-rich plasma, hyaluronic acid, and corticosteroid injections on temporomandibular joint osteoarthritis

Abstract

There are few studies in the literature that comparatively evaluate the use of intra-articular orticosteroids (CS), hyaluronic acid (HA), and platelet-rich plasma (PRP). In this study, the authors aimed to compare the clinical results of intraarticular CS, HA, and PRP injections in patients who presented to the authors’ clinic with temporomandibular joint (TMJ) pain and clinically diagnosed with TMJ-osteoarthritis. Patients were evaluated in 2 groups as those patients who felt pain on lateral (n ¼ 31), and posterior (n ¼ 43) palpation. Patients who were evaluated in the study were randomly assigned to 3 different treatment groups as Group 1 (PRP), Group 2 (HA), and Group 3 (CS). Pain felt on the TMJ on lateral and posterior palpation was assessed before treatment and every month for 3 months using a 5-point pain scale. Presence of crepitation, loss of function, and loss of strength were assessed before treatment and every month for 3 months. Significant changes were observed in the PRP and HA groups when the patients were evaluated according to the VAS scores evaluated at different follow-up times for TMJ pain on lateral palpation. Significant changes were observed in the PRP, HA, and CS groups when VAS scores were evaluated according to the patients’ follow-up times for TMJ pain on lateral palpation. In conclusion, the findings of this study have shown that intra-articular PRP injections decreased TMJ palpation pain more effectively compared with the HA and CS groups. © 2019 by Mutaz B. Habal, MD.
