This is a prospective, longitudinal, single-centre randomized pilot study with follow-up to 12 months. Participants scheduled to receive standard-of-care knee RFA for chronic knee pain related to osteoarthritis will be randomized through REDCap in a 1:1 manner to receive either the standard 3-target RFA protocol or the novel 6-target RFA protocol.
In usual clinical care, the RFA technique would typically be selected by the treating physician and both techniques are being done as standard of care. In this study, assignment to one of the two RFA techniques will be randomized. The RFA procedure itself will be completed as part of standard clinical care.
Study-related activities include randomization, collection of limited demographic and clinical information from the medical record, collection of procedural information, adverse event monitoring, and participant-reported outcome assessments. Outcomes will be collected at baseline before the procedure and at 3, 6, 9, and 12 months post-procedure. Follow-up may be discontinued at or after 6 months if the participant's pain returns to baseline levels or if the participant undergoes a repeat procedure.
