Abstract Objective To elucidate the effectiveness of ultrasound-guided genicular nerve radiofrequency ablation in alleviating pain as well as its effects on functional outcomes, quality of life and physical performance in knee osteoarthritis patients. Design Prospective observational study. Setting Patients were recruited within one community hospital. Subjects Patients with knee osteoarthritis. Methods The subjects underwent ultrasound-guided radiofrequency ablation of genicular nerves after showing a positive response to a diagnostic block. Outcome assessments were performed at baseline and at 2 and 12 weeks posttreatments using the 36-item Short Form Health Survey (SF-36), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and a physical performance evaluation including balance tests, quadriceps muscle strength test, two-minute walking test and knee joint proprioception test. Results Thirteen out of 38 patients were eligible for genicular nerve radiofrequency ablation. There were significant improvements from baseline to posttreatment in the numeric rating scale score, physical health domain score of SF-36, and pain and stiffness domain scores of the WOMAC. Regarding physical performance, the step test result significantly improved over the 12 weeks of follow-up. On the other hand, no significant deteriorations in the single leg stance test, isokinetic quadriceps muscle strength test, knee joint proprioception test or two-minute walking test results were observed after radiofrequency ablation of genicular nerves. Conclusions Radiofrequency ablation of genicular nerves may significantly alleviate pain and improve functional outcomes in knee osteoarthritis patients. More importantly, static balance control and quadriceps muscle strength were preserved and there was a change of proprioception in the good direction.

Introduction: The knee arthroplasty is the best option for patients with advanced osteoarthritis who have failed all other conservative options, but regrettably many patients fail to undergo surgery due to co-morbidities or other reasons. So, new alternative modes are always in demand for these patients. Methods: The ultrasound-guided radiofrequency ablation (RFA) of all the genicular nerves of knee joint was done in patients with grade III and IV osteoarthritis of knee joint, with severe pain (numerical rating scale (NRS) > 7) who had failed conservative management and intra-articular injections after a positive genicular nerve block with local anaesthetics. The demographics, pain intensity measured in NRS, Oxford Knee Score (OKS) and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and quality of life measured by 36-Item Short Form Health Survey (SF-36) questionnaire was measured at baseline and at regular intervals. Results: The average age of the patients was 61.50 ± 6.75 years. There was significant improvement in pain intensity at rest, movement and on weight bearing from 8.75 ± 0.5, 9.0 ± 0.0, and 9.0 ± 0.0 at baseline to 2.38 ± 0.51, 3.75 ± 0.46, and 4.13 ± 0.35 at 1 month and 3.13 ± 0.64, 4.38 ± 0.51, and 4.63 ± 0.51 at 6 months after the procedure, respectively (p value <0.05). The OKS had improved from 7.75 ± 1.25 at baseline to 28.88 ± 2.53 and 28.13 ± 1.80 at 1 and 6 months, respectively, after the procedure (p value <0.05). The WOMAC score had also improved significantly from 77.75 ± 4.34 at baseline to 38.38 ± 5.82 and 39.25 ± 5.12 at 1 and 6 months, respectively (p value <0.05). There was also significant improvement in the quality of life after the procedure (p value <0.05). Conclusion: Ultrasound-guided RFA of genicular nerves of knee joint is a good alternative option for patients who are having severe pain and disability from knee osteoarthritis and gives a long-lasting pain relief for more than 6 months.

Huo J et al. Comparative Effectiveness of Computed Tomography-Versus Ultrasound-Guided Percutaneous Radiofrequency Ablation Among Medicare Patients 65 Years of Age or Older With Hepatocellular Carcinoma. Value Health 2019; 22(3):284–292 Die Inzidenz des Leberzellkarzinoms hat sich in den letzen 20 Jahren mehr als verdoppelt. 2018 wurden in den USA mehr als 31 600 neue Fälle registriert, knapp die Hälfte dieser Patienten war älter als 65 Jahre. Die damit verbundenen jährlichen Kosten werden auf 455 Millionen US Dollar geschätzt. Für fortgeschrittene, inoperable Fälle steht die Radiofrequenzablation als Therapieoption zur Verfügung, die Ultraschall- oder Computertomographie-gestützt durchgeführt werden kann. Die Autoren vergleichen die Effektivität beider Bildgebungstechniken für das Verfahren.
