Ultra Sound Guided Genicular Nerves Cooled Radiofrequency Ablation in Total Knee Replacement Surgeries

August 4, 2026 updated by: Ain Shams University
Total Knee Replacement surgery is common procedure that is usually done for patients suffering from persistent pain with limitation of movement. Unfortunately, they do suffer after the operation as it is associated still with significant pain that affect the rehabilitation plan, hospital length of stay, life style and patient satisfaction. New approaches are rising every day to add to the multimodal management plan. Genicular nerves cooled radiofrequency ablation is a new approach that can be simply done U.S. guided with little side effects, if any, and great results.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
o Epidural rescue doses
Time Frame: 1st 48 hours
rescue doses reflects degree of pain control
1st 48 hours

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
WOMAC score
Time Frame: baseline preoperative, and the at 2, 6 and 12 weeks postoperative
assessment of the functional state of the patient and degree of pain and limitation of movement
baseline preoperative, and the at 2, 6 and 12 weeks postoperative
Knee range of motion
Time Frame: Assessed weekly for 3 weeks postoperatively (Weeks 1, 2, and 3)
Time to achieve full knee range of motion will be assessed by measuring active knee flexion and extension in degrees (°) using a universal goniometer during weekly postoperative assessments. The outcome will be reported as the number of days or weeks required to achieve full range of motion, as defined in the study protocol.
Assessed weekly for 3 weeks postoperatively (Weeks 1, 2, and 3)
Postoperative inflammatory signs assessed by clinical examination
Time Frame: Assessed weekly for 3 weeks postoperatively (Weeks 1, 2, and 3).
Postoperative inflammatory signs, including redness (erythema), local warmth, and swelling around the operated knee, will be assessed by clinical examination. Each sign will be recorded as present or absent. The outcome will be reported as the number of participants with each inflammatory sign at each assessment.
Assessed weekly for 3 weeks postoperatively (Weeks 1, 2, and 3).
