Efficacy of arthrocentesis and PRP in TMJ osteoarthritis patients

Arthrocentesis has emerged as a well-established minimally invasive procedure for temporomandibular joint osteoarthritis (TMJ-OA). Conservative therapies often provide limited and short-term symptomatic relief. Therefore it is of interest to assess the clinical efficacy of arthrocentesis combined with platelet-rich plasma (PRP) injection in reducing pain and recovering mandibular function in patients with TMJ osteoarthritis. Hence, total 38 patients diagnosed with TMJ-OA underwent arthrocentesis followed by intra-articular injection of autologous PRP. Clinical outcomes assessed included pain intensity using the Visual Analog Scale (VAS) and maximum mouth opening at 1, 3 and 6 months. Arthrocentesis combined with PRP provides sustained pain relief and functional improvement in TMJ-OA.
