PurposeThe purpose of this study is to answer the following clinical question: Among subjects with temporomandibular joint osteoarthritis (TMJ-OA), do those who undergo arthrocentesis and corticosteroid (CS) injection, when compared to those undergoing arthrocentesis alone, have better outcomes in terms of range of motion and clinical symptoms?Materials and MethodsA randomized clinical trial in adult patients with TMJ-OA referred to the authors' clinic from May 2012 and September 2013 was implemented. The sample was composed of 24 consecutive patients with TMJ-OA treated randomly with either arthrocentesis alone (the control group) or arthrocentesis plus CS injection (the CS group). The outcome variables were visual analogue scale (VAS) evaluations (i.e., masticatory efficiency, joint sounds, and pain complaints), maximal inter-incisal opening (MIO), and mandibular motions. The outcome variables were recorded at baseline and at 12 months postoperatively. Mann-Whitney U tests were used for intergroup comparison. Paired t-test and Wilcoxon signed-rank test were used for intragroup comparisons.ResultsThe sample was composed of 32 joints of 24 subjects with TMJ-OA (15 joints of 12 subjects with a mean age of 35.08 ± 14.84 years for control group; and 17 joints of 12 adult patients with a mean age of 32.58 ± 9.58 years for CS group). Pain complaints and joint sounds decreased statistically (P < .01) in both groups, while painless interincisal opening increased statistically (P < .001) only in the CS group. After estimating differences between the follow-up and baseline outcomes, the mean change in the primary outcome variables showed no statistically differences between 2 groups (P > .05).ConclusionThese findings suggest that arthrocentesis plus intra-articular corticosteroid injection produced no better outcomes in terms of range of motion and clinical symptoms of patients with TMJ-OA, compared to those undergoing arthrocentesis alone.
