ObjectivesTo investigate the preoperative variables of patients with articular disc displacement without reduction (DDWOR) that may influence the results of arthrocentesis on joint effusion (JE).Study designThe records of 203 patients with clinical signs and symptoms of unilateral painful DDWOR and JE, confirmed by magnetic resonance imaging (MRI), and treated with arthrocentesis were selected. The following preoperative data were recorded: gender; age; joint side; pain duration; pain intensity, measured with the visual analogue scale; and maximum interincisal distance (MID). All patients underwent a second MRI examination 3-4 months postoperatively to assess JE condition. The sample was then divided into two groups: Group 1 (N=160) – patients presenting no signs of JE; and Group 2 (N=43) – patients still presenting signs of JE. Univariate and multivariate analysis were used to compare the groups.ResultsAmong the studied variables, pain duration (p=0.1756), pain intensity (p=<0.0001), and MID (p=0.0085) were shown to affect arthrocentesis outcomes. The longer the pain duration (OR=0.930), the more intense the pain (OR=0.346), and the smaller the MID (OR=0.562), the less the chance of arthrocentesis completely eliminating JE.ConclusionsPain duration, pain intensity, and MID could be used as predictors for arthrocentesis on JE outcomes and considered during treatment planning.
