Standard Versus Novel RFA for Chronic Knee Pain in Osteoarthritis
A Prospective Pilot Study Comparing Standard and Novel Radiofrequency Ablation Protocols for Chronic Knee Pain in Osteoarthritis
Brief Summary
The goal of this pilot study is to evaluate the feasibility and safety of conducting a randomized comparison of two standard-of-care knee radiofrequency ablation (RFA) techniques in adults with chronic knee pain related to knee osteoarthritis.
Participants who are already scheduled to receive knee RFA as part of their standard clinical care will be randomized to receive either a standard 3-target (standard) RFA protocol or a 6-target (novel) RFA protocol. The main purpose of this pilot study is to determine whether a future larger randomized trial comparing these two RFA approaches is feasible and safe to conduct.
Participants will complete questionnaires about pain, knee function, and stiffness at baseline and at follow-up timepoints for up to 12 months after the RFA procedure. Preliminary pain relief outcomes will also be explored to help inform the design of a future definitive trial.
Participants already scheduled for a knee RFA procedure as part of their standard of care for pain related to knee osteoarthritis will answer online survey questions about their pain for up to 12 months.

Detaillierte Beschreibung
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.

Waffen und Interventionen
Teilnehmergruppe / Arm |
Intervention / Behandlung |
|---|---|
|
Aktiver Komparator: Traditional RFA
Participants randomized to this arm will receive the standard 3-target knee RFA protocol as part of their standard clinical care.
|
X-ray imaging is used to guide needles that target the superior lateral, superior medial, and inferior medial genicular nerves surrounding the knee, heat is used to ablate the nerves.
|
|
Aktiver Komparator: Novel RFA
Participants randomized to this arm will receive the 6-target knee RFA protocol as part of their standard clinical care.
|
X-ray imaging is used to guide needle placement for radiofrequency ablation targeting the superior lateral, superior medial, and inferior medial genicular nerve regions around the knee.
The 6-target protocol also includes supplementary ablation lesions at three additional target sites around the knee.
These additional targets are treated by adjusting the needle angle once inserted, without requiring additional needle insertions beyond the standard approach.
