Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Radiofrequency (RF) treatment has been used for several painful conditions such as trigeminal neuralgia, cancer pain, and spinal pain. To destroy nerves or disrupt the transmission of pain signals, originally using producing heat lesions, RF current is applied to the trigeminal ganglion, the spinothalamic tracts of the spinal cord, the medial branches of posterior rami, and the dorsal root ganglion. In addition to these, there have been a few attempts to apply RF current for the treatment of painful conditions of joints of the extremities.
Percutaneous radiofrequency ablation (RFA) of articular sensory nerves has recently emerged as an attractive and minimally invasive approach to treat chronic pain due to large-joint osteoarthritis in select patients.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Percutaneous radiofrequency group
Patients will receive percutaneous radiofrequency.
Percutaneous radiofrequency
For the percutaneous radiofrequency treatment, a medium electrode size will be placed on either side of the knee: one skin electrode on the inside and one on the outside of the knee for 15 minutes.
Conventional radiofrequency group
Patients will receive conventional radiofrequency.
Conventional radiofrequency
For the conventional radiofrequency treatment, a 50 Hz sensory stimulation will be performed with a 10 cm, 22 gauge, 10 mm active tip radiofrequency cannula. After receiving the appropriate sensory and motor stimuli, a radiofrequency of 90°C will be applied for 90 s.
