No statistical differences were observed between the two groups in terms of the consumption of major opioids or complications of the technique, except for a higher incidence of motor block in the ultrasound-guided group (Bromage scale II: 0% vs 13.2%, p=0.15), which was not clinically relevant.\n\nThe degree of patient satisfaction was high in both groups, with no differences being found.Conventional radiofrequency of the geniculate nerves of the knee significantly reduces pain intensity over a period of at least 6 to 12 months in patients with chronic postoperative gonalgia, with the ultrasound-guided technique presenting the lowest scores on the numerical pain scale.\n\nIt is a simple technique to perform and with few adverse effects, which allows patients to reduce the dose of opioid drugs they take chronically."}, "eligibilityModule"=>{"sex"=>"ALL", "stdAges"=>["ADULT", "OLDER_ADULT"], "minimumAge"=>"18 years", "samplingMethod"=>"NON_PROBABILITY_SAMPLE", "studyPopulation"=>"Due to the reason that it is a retrospective study, sample size calculation was not performed and all patients who underwent this analgesic technique in the last 5 years were consecutively included.\n\nContinuous quantitative variables were expressed as mean and standard deviation, and the results were contrasted using the Student's T test if data reached normality criteria.
