Temporomandibular joint (TMJ) dysfunction is a common condition that is best evaluated with magnetic resonance (MR) imaging. The aim of this study was to investigate the characteristics of the patients with TMJ osteoarthrosis on MR imaging. Methods The MR images of 206 TMJs of 103 patients with temporomandibular disorders (TMD) were evaluated retrospectively in this study. The relationship between osteoarthrosis and age, gender, TMJ pain and MR imaging findings, such as disc displacement with or without reduction and TMJ effusion, was analysed. Results The patients with TMJ osteoarthrosis (mean: 51.6 years) were significantly older than those without osteoarthrosis (mean: 44.8 years, P = 0.027). The incidence of the patients with TMJ osteoarthrosis was significantly different between with (10.0 %) and without reduction (57.0 %, P < 0.001). Logistic multivariate regression analysis demonstrated that disc displacement without reduction was significant in patients with TMJ osteoarthrosis (odds ratio = 12.285, P < 0.001). Conclusions This study suggests that characteristics of the patients with TMJ osteoarthrosis on MR imaging include older and disc displacement without reduction.
