An analysis comparing different probe sizes and technologies has not yet been undertaken for this indication. This large retrospective, comparison study from a single-center comprehensive pain management practice aims to do that.Methods: Outcomes of 170 patients who underwent traditional radiofrequency ablation (tRFA) for chronic knee pain were compared to 170 consecutive patients who received cooled radiofrequency ablation (CRFA) with similar (p=0.5) pre-procedural pain scores.Results: The VAS pain score at the first post-procedure visit at 4– 6 weeks decreased to 5.07± 2.8 cm for tRFA and to 4.26 ± 3.2 cm for CRFA (p< 0.001 for both from baseline). The difference was profound and significantly better in the favor of CRFA (p< 0.001) as the duration of reduction of pain scores by greater than 50% was 2.6 months for tRFA and 11.1 months for CRFA. There were only 15 patients (8.8%) who continued to receive > 50% of pain relief in tRFA at 12 months, as opposed to 78 (46%) at 12 months for CRFA. We compared the initial outcomes and long-term pain relief. Long-term outcomes were better for the bigger lesion size treatment group patients.Conclusion: We conclude that the duration and intensity of pain relief were of a greater magnitude after the larger diameter probe cooled RFA.Keywords: radiofrequency ablation, chronic knee pain, knee osteoarthritis, pain management |
