The Long-Term Efficacy of Radiofrequency Ablation With and Without Steroid Injection.

Background Radiofrequency ablation (RFA) has been proven to be an effective option for treating chronic low back pain. In addition to RFA as a treatment modality, the administration of concomitantly to minimize the effect of hyperalgesia is common practice. However, there is insufficient evidence about the long-term outcomes of their use. Methods This was a retrospective study that examined 239 patients who received spine, knee joint, and sacroiliac joint RFA between June 2014 and June 2018. Pre- and post-procedure pain scores, percent improvements, and duration of relief were included in our review. Subjects This study included 239 patients of which 191 patients received steroids with their RFA. Results These 191 patients experienced an average improvement of 48.48% relief for an average of 137.52 days. Forty-eight patients did not receive steroids with RFA and had an average improvement of 46.36% for an average of 126.10 days. The statistical analysis revealed there was no significant difference between the two groups for percent improvement (p = 0.71) and duration of relief (p = 0.67). Conclusions Patients who received steroids with RFA compared to RFA alone did not differ significantly in percent improvement in pain and duration of relief.
