Cocogen Trial: COoled Versus COnventional Radiofrequency Treatment of

Status Completed

Clinical Trial Summary

Knee osteoarthritis is a progressive degenerative process that affects joint cartilage and the subchondral bone. Approximately 10% to 30% of all osteoarthritis patients suffer from disabling symptoms such as pain, stiffness and loss of function leading to psychological and sleeping disorders and a diminished quality of life. When conservative treatment fails to treat the symptoms, a total knee arthroplasty can be performed. However, this procedure is not suitable for all patients. For these specific groups of patients a radiofrequent treatment of the genicular nerves might be an alternative treatment option. Multiple researchers investigated the effect of conventional and later also, cooled radiofrequent treatment of the genicular nerves, with promising results for both techniques. However, the techniques have never been compared in a randomised controlled trial. This study is designed to assess the feasibility of conducting a large RCT comparing pain relief and costs after a conventional radiofrequency treatment of the genicular nerves (superomedial, superolateral and inferomedial) versus a cooled radiofrequency treatment.

Clinical Trial Description

This pilot study is designed as a prospective, multicentre, double blind, randomised controlled non-inferiority trial. The total follow up time is 6 months with follow up assessments at 1, 3 and 6 months post intervention. It is estimated that the total duration of data collection will cover 1 year. Adult patients (> 18 years) with chronic, moderate to severe knee pain (NRS>4) due to osteoarthritis, radiological diagnosed to be graded 2-4 according to the Kellgren-Lawrence criteria or with persistent postoperative moderate to severe knee pain (NRS>4) after total knee arthroplasty can be included in the study. Patients will be randomly selected for treatment with conventional radiofrequent treatment or cooled radiofrequent treatment of the SL, SM and IL genicular nerves. In total, three hospitals participate in this study: Ziekenhuis Oost-Limburg (Belgium), Maastricht UMC+ (Netherlands) and Rijnstate (Netherlands). ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
