OBJECTIVE: Temporomandibular joint disorders (TMDs) are a common source of orofacial pain and dysfunction. Arthrocentesis of the temporomandibular joint (TMJ) is a minimally invasive treatment that can be augmented with intra-articular injections. This study aimed to compare the clinical efficacy of platelet-rich plasma (PRP) versus hyaluronic acid (HA) injections following TMJ arthrocentesis in patients with TMDs unresponsive to conservative therapy.
METHODS: Sixty patients (72 joints) were randomized into three equal groups. Group A underwent arthrocentesis with Ringer's lactate (RL) alone (control), Group B received PRP injection post-arthrocentesis, and Group C received HA injection post-arthrocentesis. Pain intensity (VAS), maximum mouth opening (MMO), and TMJ sounds were evaluated at baseline, 1 week, 12 weeks, and 24 weeks. Repeated-measures ANOVA and chi-square tests were used for analysis (p < 0.05).
RESULTS: All groups showed significant improvements in pain and MMO over time. Mean VAS pain scores decreased from ~ 4.8 to < 1.0 at 24 weeks (p < 0.001), while MMO increased from ~ 32 mm to ~ 40 mm (p < 0.001). No significant differences were found between the PRP and HA groups in pain or function at any follow-up point, nor between either treatment group and the control group. TMJ clicking resolved or improved in > 95% of joints across all groups. No adverse events were recorded.
CONCLUSION: TMJ arthrocentesis alone provides substantial pain relief and functional gains. PRP and HA did not confer additional benefit over lavage alone within the 6-month timeframe. Further studies are required to assess any potential long-term differences.
