Comparison of ultrasound guided intra-articular injection of platelet rich plasma and triamcinolone acetonide in the reduction of pain and functional improvement in primary temporomandibular joint osteoarthritis: A randomized controlled trial

temporomandibular joint osteoarthritis (TMJ OA) affects 5-12% of world population and is more prevalent in india with 22-29%  occurrence and without intervention it negatively affects quality of life. primary TMJ OA is characterized by absence of distinct local or systemic factors. there are many trreatment options like occlusal splint, NSAIDs, I/A steroid injection, hyalouronic injection, but with recent advancement and studies coming up with platelet rich plasma (PRP) showing it’s anti- inflammatory and regenerative properties makes it novel treatment option for management of pain and function among patients suffering with TMJ OA . This study will be conducted to compare the efficacy of I/A injection under ultrasound guidance of steroid (triamcinolone acetonide) with PRP  in reduction of pain and functional improvement in primary cases of TMJ OA . Study will be a randomized controlled trial conducted in Regional Institute of Medical Science, Imphal.

outcome measures will be measured at baseline at 1, 4, 12 and 24 weeks respectively. Data will be analyzed using IBM-SPSS 25 version, for descritive data chi square will be used and for comparative data student t test,  paired t test and ANOVA will be used and p value of <0.05 will be taken as significant
