Comparison of the Efficiacy of Intra-Articular Injection of Liquid Platelet-Rich Fibrin and Hyaluronic Acid After in Conjunction With Arthrocentesis for the Treatment of Internal Temporomandibular Joint Derangements

Comparison of the Efficiacy of Intra-Articular Injection of Liquid Platelet-Rich Fibrin and Hyaluronic Acid After in Conjunction With Arthrocentesis for the Treatment of Internal Temporomandibular Joint Derangements: The aim of this study was to evaluate the effectiveness of intra-articular injection of liquid platelet-rich fibrin (I-PRF) versus hyaluronic acid (HA) following arthrocentesis in patients suffering from temporomandibular joint (TMJ) pain and dysfunction. A total of 69 patients with internal TMJ derangement were enrolled in this retrospective, matched cohort study. A total of 47 included patients (67 joints) were divided into 3 groups as follows: 16 participants in the arthrocentesis-only group; 14 patients in the arthrocentesis plus HA injection group (A+HA); and 17 participants in the arthrocentesis plus I-PRF injection group (A+I-PRF). The 2 outcome variables were TMJ pain and maximal mouth opening (MMO) which were evaluated up to 12 months postoperatively. The data were analyzed using the Shapiro–Wilk test, Kruskal–Wallis test, Mann–Whitney U test, Wilcoxon sign test, Fisher exact test, and the χ2 test. Statistically significant decreases in pain scores and increases in MMO values were observed in all 3 groups during the 12 months of follow-up. The significant decrease in pain values was shown in the A+I-PRF group as compared with the A+HA group at 9 months postoperatively. MMO values in the A+I-PRF group were significantly higher than in the A+HA group at 9 and 12 months postoperatively. All conventional treatment procedures can provide pain reduction and improvement to MMO. However, intraarticular injections of I-PRF in combination with arthrocentesis showed superior performance in terms of the gradual improvement in pain alleviation and range of mouth opening.
