Despite numerous pharmaceutical options, the majority of patients still experience long-term pain. Genicular nerve (GN) radiofrequency has become increasingly popular as a treatment for knee pain. This retrospective study aimed to evaluate the effects of pulse dose radiofrequency (PDRF) in patients with chronic knee OA pain.PatientsandMethods: Propensity score matching analysis was performed in a retrospective cohort of 78 patients with moderate-severe knee OA pain unresponsive to conservative treatment who underwent PDRF GN or intra-articular (IA) and PDRF GN.Pain relief was measured using the numeric rating scale (NRS), Western Ontarioand McMaster Universities Osteoarthritis Index(WOMAC) and Patient Global Impression of Change (PGIC) at 3 and 6 months post-intervention.Results: A significant reduction in NRS scores was reported at 3 (p< 0.001) and 6 months (p< 0.001) after PDRF in both groups. NRS was lower in PDRF IA + GN than PDRF GN (p< 0.0001). WOMAC pain was significantly reduced at 3 months in PDRF IA + GN group (baseline: 10.12± 3.14, 3 months: 6.25± 2.44, p=0.0001). WOMAC stiffness and function were improved only at 3 months in PDRF IA + GN compared to baseline (p=0.007 and p=0.006, respectively).A longer period of pain relief was reported after PDRF IA + GN (6.75± 2.42 months) compared to PDRF GN (4.31± 2.85 months, p< 0.001) in association with higher PGIC scores.Conclusion: This is the first study that compared two different PDRF techniques. PDRF GN and PDRF IA + GN were both effective in reducing pain at 3 and 6 months follow-up. However, only PDRF IA + GN was able to improve WOMAC scores at 3 months after the treatment with a longer period of efficacy compared to PDRF GN alone.Keywords: knee pain, pulse dose radiofrequency; PDRF, radiofrequency; genicular nerve, osteoarthritis, chronic pain, WOMAC, interventional pain management |
