Trial summary
the aim of our study is to compare effectiveness (satisfaction) and duration of pain relief between patients receiving the conventional thermal radiofrequency on the genicular nerves alone vs patients who will receive the conventional method plus alcohol neurolysis of the targeted nerves.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
genicular nerve ablation by thermal radiofrequencyProcedure or surgery
radio-frequency will be done using the Neurotherm NT1100 re-generator. The 3 entry sites will be detected under fluoroscopy then local anesthesia will be performed using lidocaine 2% followed by the insertion of the 3 radiofrequency cannulas (STRYKER 20 G, 9 cm with 1 cm active tip) targeting the 3 main nerves ( superior medial genicular, superior lateral genicular and the inferior medial genicular nerves ) .
A confirmation of the targeted sites is done under fluoroscopy in both A-P and lateral views then a motor stimulation will be done to ensure no undesirable motor response followed by lidocaine 1 % injection and placing of the radiofrequency cables and ablation was done at 80 degrees for 90 seconds . The procedure will be repeated 3 times at different levels in the lateral view separated by 0,5 cm to ensure successful targeting. Then remove the needles.
genicular nerve ablation by thermal radiofrequency plus alcohol neurolysisProcedure or surgery
radio-frequency will be done using the Neurotherm NT1100 re-generator. The 3 entry sites will be detected under fluoroscopy then local anesthesia will be performed using lidocaine 2% followed by the insertion of the 3 radiofrequency cannulas (STRYKER 20 G, 9 cm with 1 cm active tip) targeting the 3 main nerves of the knee.
A confirmation of the targeted sites is done under fluoroscopy in both A-P and lateral views then a motor stimulation will be done to ensure no undesirable motor response followed by lidocaine 1 % injection and placing of the radio-frequency cables and ablation was done at 80 degrees for 90 seconds . The procedure will be repeated 3 times at different levels in the lateral view. After the radiofrequency is done at each level a 1 ml of 70% alcohol will be injected making a total of 3 ml injection to each nerve Then remove the needles.
| Study group | Role | What they receive |
|---|---|---|
| control group | Active comparator | The patients are placed in supine position with knee preparation using an iodine-based product and drape in a sterile manner Then the ground pad of the radio frequency machine will be placed in the other leg (we used the Neurotherm NT1100 re generator) All the patients will be monitored by ECG, noninvasive blood pressure and pulse oximetry The 3 entry sites will be detected under fluoroscopy then local anesthesia will be performed using lidocaine 2% followed by the insertion of the 3 radiofrequency cannulas (STRYKER 20 G, 9 cm with 1 cm active tip) targeting the 3 main nerves ( superior medial genicular, superior lateral genicular and the inferior medial genicular nerves ). this group will receive radio frequency alone .

| study group | Experimental | this group will pass through the all steps but after the radiofrequency is done at each level a 1 ml of 70% alcohol will be injected making a total of 3 ml injection to each nerve. Receives: Procedure: genicular nerve ablation by thermal radiofrequency; Procedure: genicular nerve ablation by thermal radiofrequency plus alcohol neurolysis |
What is being measured

Questions about this trial
What is this clinical trial studying?
A study testing genicular nerve ablation by thermal radiofrequency and genicular nerve ablation by thermal radiofrequency plus alcohol neurolysis in people with Knee Osteoarthritis, run by Ain Shams University at 1 site in Egypt.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

The record says: status not confirmed, as of the sponsor's last update on 8 Aug 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Egypt. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Lydia E Zakhary, MD (00201222555128, lydia_zakhary@med.asu.edu.eg), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
pain relief after 1 month (time frame: 1 month). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05980338, which also lists 3 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Aug 2023; AzTrials last refreshed its copy on 7 Nov 2026.
