简要总结
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.

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.
The following were measured as secondary variables: the degree of motor block, the reduction in the consumption of opioid drugs, the ease of performing the technique, the degree of patient satisfaction, the appearance of adverse effects and complications related to the technique.
A total of 57 patients were included in the study (19 scopic group and 38 US group). Both techniques were shown to be effective for the control of chronic knee pain. There was a statistically significant reduction in pain intensity at 3, 6 and 12 months (3 [1-5] vs 2 [0-3]; p=0.02 / 3 [2-5] vs 2 [0-3]; p=0.00 / 4 [2-5] vs 2 [1-3]; p=0.00), as well as a reduction in minor opioid requirements (52.6% vs 18.4% p=0.001) in the ultrasound-guided group. No statistical differences were observed between the two groups in terms of the consumption of major opioids or complications of the technique, except for a higher incidence of motor block in the ultrasound-guided group (Bromage scale II: 0% vs 13.2%, p=0.15), which was not clinically relevant.
