Approximately 15% to 45% of chronic low back pain is due to facet joint arthropathy. Currently, no large\u2010scale retrospective studies have investigated long\u2010term clinical predictors of success in individuals receiving radiofrequency ablation (RFA) of the medial branches for facet joint arthropathy.<\/jats:p><\/jats:sec><jats:sec><jats:title>Objective<\/jats:title><jats:p>To determine the clinical factors associated with success and failure of RFA of lumbar facet joints at 1\u2010year follow\u2010up.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Clinical data were gathered from 500 consecutive patients with an International Classification of Diseases (ICD)\u201010 diagnosis of lumbar spondylosis. VAS pain scores for patients undergoing lumbar medial branch RFA procedures were recorded at multiple time points, up to the 1\u2010year follow\u2010up visit. A responder was defined as\u00a0having \u226530% improvement in VAS score from the pre\u2010procedural VAS score. For our primary analysis, regression analysis was conducted to identify associations between responder status and patient characteristics, including age, gender, body mass index (BMI), hormone use, opiate dose, and smoking history at multiple time points, up to the 1\u2010year follow\u2010up visit.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 500 patients were included in the study. At the 1\u2010year post\u2010RFA follow\u2010up visit, responder status was associated with a lower rate of prior opioid use (43.22% vs. 55.76%, odds ratio 0.60 [95% confidence interval (CI) 0.40 to 0.92], <jats:italic>P<\/jats:italic>\u00a0=\u00a00.018), lower pre\u2010procedural opioid consumption in oral morphine equivalents (10.16\u00a0\u00b1\u00a016.02 vs. 14.67\u00a0\u00b1\u00a020.65, \u03b2 \u22124.50 [95% CI \u22128.57 to \u22120.44], <jats:italic>P<\/jats:italic>\u00a0=\u00a00.030), and a higher pre\u2010VAS pain score (6.36\u00a0\u00b1\u00a02.17 vs. 5.85\u00a0\u00b1\u00a02.17, \u03b2 0.50 [95% CI 0.06 to 0.95], <jats:italic>P<\/jats:italic>\u00a0=\u00a00.028).
