Background and Aims:
Pulsed radiofrequency is the application of a high-frequency current with microseconds pause. This modality is a non-invasive one and it does not produce pain.
Methods:
We describe 3 cases of knee pain in elderly patients where the Surgery had been dismissed. We measured the efficacy in reducing the pain and how long did it last.
Results
2 of them experienced a reduction of more than 90 % of the pain. The other one only experienced an improvement of 50 % of the pain. The pain improvement lasted mínimum three months with the option to repeat this therapy.
Conclusions:
Transcutaneous pulsed radiofrequency can be a non-invasive treatment for the painful knee with a high effectivity. More research might be conducted.
