Posted 07 Feb, 2019 [ssba]

Advanced age usually suffer from painful osteoarthritis of knee (OA). Treatment of OA pain by non- steroidal anti-inflammatory is of restricted benefit and surgery is challenging in many patients due to associated medical problems. In this study we used either intraarticular PRF or radiofrequency neurotomy to control pain in patients with chronic knee pain.

Aim: The primary outcome of the study was the pain score 10 cm Visual Analog Scale (VAS). The secondary outcome of the study was (1) WOMAC scores (2) Amount of analgesic medications.

Methods: This study was conducted on 100 adult patients more than 60 years with chronic knee pain (grade 3 or grade 4) osteoarthritis. Patients were divided into two groups each group contain 50 patients. In group I (intraarticular PRF), patients were treated with PRF where patient was placed in a supine position on the fluoroscopy table, knee joint was flexed to 15°, No genicular block tests were performed. Group 2 (radiofrequency neurotomy), patients were treated with radiofrequency neurotomy. Where patients were placed in a supine position on the fluoroscopy table, knee joint was flexed to 15° and genicular block tests were performed.
