An interventional study of RF treatment and radiofrequency ablation in Painful Osteoarthritis of the Knee, sponsored by Hospital General de Jerez de la Frontera. Completed at 1 site in Spain. Per ClinicalTrials.gov, last updated 2016-02-23.

Pharmacological treatment of pain due to osteoarthritis of the knee often proves to be inadequate and/or cause intolerable side effects. Arthroplasty of the knee may offer a solution, but waiting lists may be long or certain patients may not be apt for a surgical intervention. Therefore an alternative pain treatment that is effective and has little side effects allowing to offer pain relief to those difficult to manage patients would be an added value in the therapeutic options.
We studies the short and long-term effects of radio frequency treatment of the genicular nerves in patients with severe pain due to osteoarthritis of the knee.
Radio frequency treatment (RF) of the genicular nerves was found to be effective in a randomized controlled trial. Because of the blinding patients were allowed to continue pre-intervention pharmacological treatment, which may have interfered with the outcome. The short follow-up (12 weeks) does not allow drawing conclusion on the duration of the effect.
We aimed at assessing the pain reducing effect of RF of the genicular nerves and the duration of the effect.
4,398 studies on the registry are indexed under Osteoarthritis; 582 are open to participants now.

Exclusion Criteria:
Patients treated with radio frequency of the genicular nerves
Procedure: RF treatment · Radiation: radiofrequency ablation · Device: ultrasound
the genicular nerves are identified with the help of landmarks, ultrasound and nerve stimulation. Once the needle is correctly placed high frequency current is passed through the probe during 90 seconds at 20 V with tip temperature put to 80°C.
Pain reduction
Pain intensity is measured using a 10-point VAS score
Time frame: 1, 6 and 12 months
Global patient satisfaction
Satisfaction is scored on a 4-point Likert scale: 1 (poor), 2 (average), 3 (good) and 4 (very good)
Time frame: 1,6 and 12 months
Improvement of quality of life
evaluated using the Western Ontario and MacMaster Universities Index of Osteoarthrosis (WOMAC)
Time frame: 1,6 and 12 months
