Brief summary (from the registry)
Knee osteoarthritis is one of the most common joint conditions in the elderly population, characterized by causing pain, stiffness and functional disability in a significant number of cases. Retrospective, non-randomized observational study, between January 2019 and January 2024, comparing the analgesic effectiveness of conventional radiofrequency of the geniculate nerves performed in a cohort of patients with a scopy-guided technique (scopic group, N=19) versus the ultrasound-guided technique (US group, N=38) in patients referred to the pain unit for chronic gonalgia of moderate-severe intensity after knee surgery. The main variable studied was the measurement of pain intensity according to the numerical rating scale (NRS) before performing the technique and at 3, 6 and 12 months after radiofrequency denervation of the geniculate nerves. Conventional radiofrequency of the geniculate nerves of the knee significantly reduces pain intensity over a period of at least 6 to 12 months in patients with chronic postoperative gonalgia, with the ultrasound-guided technique presenting the lowest scores on the numerical pain scale. It is a simple technique to perform and with few adverse effects, which allows patients to reduce the dose of opioid drugs they take chronically.
