Genicular Radiofrequency Ablation Efficacy in Achieving Total Knee Pain Reduction Trial

Study Purpose

Given the benefits of genicular nerve radiofrequency ablation (RFA) in improving pain and functional status in non-surgical patients with knee osteoarthritis as well as the high prevalence of postoperative pain from total knee arthroplasty (TKA), this study is designed to determine the efficacy of preoperative genicular nerve RFA in improving acute and chronic postoperative pain as well as functional status in patients undergoing TKA. Patients will be randomized to one of two study arms: RFA group (genicular nerve thermal RFA) or control group (RFA needles placed in proper location without effective neurotomy).

Recruitment Criteria

Accepts Healthy Volunteers Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms	No
Study Type An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies.	Interventional
Eligible Ages	45 Years - 79 Years
Gender	All

Trial Details

Trial ID: This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.	NCT02947321
Phase Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans. Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data. Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs. Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.	N/A

Additional Details

Total knee arthroplasty (TKA) is a common and effective treatment for severe knee osteoarthritis. As the average age of the population increases in developed countries, the number of TKAs performed is projected to increase to 3.48 million procedures per year by 2030, a 673% increase from 2005. Although TKA is widely accepted as an efficacious form of treatment for severe knee osteoarthritis, the incidence of patient dissatisfaction and postoperative pain cannot be ignored. Genicular nerve RFA has been performed in non-surgical patients with chronic knee osteoarthritis with significant post procedure improvement in pain and functional status. This study is designed to determine the efficacy of preoperative genicular nerve RFA in improving acute and chronic postoperative pain as well as functional status in patients undergoing TKA.
