- Brief Summary
This study aims to compare percutaneous and conventional radiofrequency applications for the treatment of knee osteoarthritic pain.
- Detailed Description
Osteoarthritis (OA) is a progressive degenerative joint disease that affects the joint cartilage and surrounding tissues. It mostly affects the weight-bearing joints, and in this respect, the knee joint is one of the joints that is most affected.
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.

Group Intervention Description Conventional radiofrequency group Conventional radiofrequency Patients will receive conventional radiofrequency. Percutaneous radiofrequency group Percutaneous radiofrequency Patients will receive percutaneous radiofrequency.
- Primary Outcome Measures
Name Time Method Degree of pain 12th week post-procedure Degree of pain will be assessed using visual analog scale (VAS). Each patient will obtain a score between 0 and 10 (Zero means no pain, and ten means the worst pain). VAS will be assessed pre-procedure and post-procedure 2nd, 6th, and 12th week.
- Secondary Outcome Measures
Name Time Method Incidence of adverse events 12th week post-procedure Incidence of adverse events such as bleeding, neurological damage, infection, abnormal proprioception, numbness, paresthesia, and motor weakness will be recorded.
Patient satisfaction 12th week post-procedure Degree of patient satisfaction will be assessed on a 5-point Likert scale Patient satisfaction (1, extremely dissatisfied; 2, unsatisfied; 3, neutral; 4, satisfied ; 5, extremely satisfied). It will be assessed pre-procedure and post-procedure 1, 4, and 12th week.
Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores 12th week post-procedure Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores: range from 0 to 96 (0 represents the best health status and 96 the worst possible status). The higher the score, the poorer the function. It will be assessed pre-procedure and post-procedure 1, 4, and 12th week.
