Treatment options include physical therapy, analgesics, anticonvulsants, exercise, and muscle relaxants. Even with conventional treatment modalities, in a subset of patients, pain may persist. Cooled radiofrequency ablation (c-RFA), a minimally invasive therapy, employs thermal energy generated by electrical currents to disrupt the transmission of pain stimuli along nociceptive pathways. This leads to an attenuation of pain impulses, primarily through nerve tissue necrosis. The potential of c-RFA to alleviate chronic pain for patients who struggle to find relief elsewhere accentuates the importance of rigorously investigating its outcomes. This study investigates whether patients receiving c-RFA for relief of chronic neck pain caused by cervical facet joint arthropathy experience a reduction in pain scores, the length of this reduction in pain scores, and the magnitude of this reduction in pain.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;This study was a retrospective analysis of data extracted from UW-Health Electronic Medical Health records (EMR), encompassing cervical c-RFA procedures performed from 2015 through 2022. Patient data were obtained, including diagnosis, pre-operative pain score, post-operative pain score, duration of relief, patient age, sex, and BMI. A two-tailed paired t-test was used to statistically analyze the pre-operative and post-operative pain scores, in which a p-value ≤0.05 was considered significant.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;A total of 450 cervical c-RFA procedures were reviewed, 152 were excluded due to absent pre- or post-op pain scores. 298 were included in the analysis, comprising 203 unique patients: 129 females and 74 males with an average age of 56.03 ± 12.76 and a BMI of 28.76 ± 6.05. Improvement of pain symptoms was reported in 85.23% (n = 263), 6% (n = 19) reported complete pain remission, 8.72% (n = 26) reported no change, and 3.02% (n = 9) reported worsening symptoms. Patients reported an average pre-operative pain score of 6.15 (M = 6.15, SD = 1.55) and an average post-operative pain score of 3.64 (M = 3.64, SD = 2.09) this achieved significance (p &lt; 0.0001). Of the 85.23% (n = 263) charts that noted improvement, there is an average of 48.04% ± 26.53 reduction from their pre-operative pain scores. The average duration of relief lasted 6.67 ± 4.84 months.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusion: &lt;/strong&gt;This study supports the potential efficacy of c-RFA as a minimally invasive treatment for chronic neck pain secondary to cervical facet joint arthropathy refractory to conventional treatment measures, demonstrating significant relief for a substantial length of time.
